==============================CHAIRMAN'S MESSAGE================================

DEAR FELLOW SHAREHOLDERS:

The Year 2000 is fast approaching and people around the world are getting ready
to celebrate this historic transition to a new millennium. At John Hancock
Funds, we share the excitement, but we aren't popping the champagne corks just
yet. Rather, we are staying on the course that we set more than two years ago to
ensure that the transition to a new millennium is a smooth one for our
shareholders.

As many already know, the Year 2000 has created more than the prospect of New
Year's festivities of epic proportions. It has also presented the world with a
challenge: making sure that older computers, and any equipment powered by
computer chips, can properly read and process the date "00" as 2000, not 1900.
Much has been written about how the world will weather the change. Some view it
as a non-event, while others see the potential for disruptions. How much
disruption, and for how long, depends on whom you talk to.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief Executive
Officer, flush right next to second paragraph.]
- --------------------------------------------------------------------------------

As a company, we recognize that the Year 2000 ("Y2K") phenomenon is an important
issue to be dealt with and we have made it a top priority. Two years ago, John
Hancock Funds put a full-time team of experts on the case and established a
company-wide program to evaluate all computer applications and to modify or
replace those that needed changing.

These modifications and replacements are nearly done, and the tests of all our
systems are on schedule for completion by the end of July. The rest of 1999 will
be spent testing with our business partners and continuing to participate in
industry testing. We have also established additional contingency plans beyond
our regular ones to prepare for any challenges that the Year 2000 might present.
In the end, John Hancock will spend approximately $90-$95 million to ensure we
make a successful transition to the Year 2000.

Throughout 1999, each of our quarterly "Fundamentals" newsletters is featuring
articles with more detailed information on Y2K matters of importance to our
shareholders. I encourage you to read them, or contact one of our Customer
Service Representatives at 1-800-225-5291 for another copy. For your own peace
of mind, we also recommend that you save your 1999 statements, especially those
you receive between October and December, so that you are able to check them
against the first one you receive in 2000. It's a measure of prudence, not
panic. Good record keeping is part of good planning.

No one knows how the dawning of the new millennium will unfold. Although we
cannot make any ironclad assurances, we are confident that the steps we have
taken will provide shareholders with as smooth a transition as possible. Once
that occurs, we will happily raise our glasses to toast the New Year, future
prosperity and our hopes to serve you well into the 2000's. Sincerely,

/s/Edward J. Boudreau, Jr.

                               Portfolio Managers

                             Large Cap Growth Fund

                         Fund posts double-digit gains
                         -----------------------------

Effective June 1, 1999, John Hancock Growth Fund was renamed John Hancock Large
Cap Growth Fund to better describe how the Fund invests.

Recently, David Eisenberg, senior vice president and chief equity strategist for
John Hancock Funds, assumed leadership of the Fund's management team on an
interim basis, joining fund management team members Geoffrey Plume and John
Golden.

The turmoil in the global financial markets during the late summer and early
fall of 1998 began to dissipate as the John Hancock Large Cap Growth Fund began
fiscal 1999 in November. By the time the Federal Reserve Board enacted its third
consecutive interest-rate cut on November 17, investors were beginning to have a
more positive outlook for U.S. economic growth and corporate profitability. When
the economic statistics for the fourth quarter of 1998 were tallied early in the
new year -- GDP rose a stellar 6%, unemployment hit a 29-year low and inflation
remained historically low -- the results were enough to power the market upward
to record heights during the first four months of 1999.

         The Dow Jones Industrial Average surged across the 10,000 point mark on
March 29 and rushed headlong toward the 11,000 point mark by the close of the
Fund's semiannual period. The S&P 500 Index also hit record levels in recent
months. In all the euphoria, it was easy to lose sight of the fact that until
April, the market's advance was largely due to the performance of a narrow band
of stocks -- the mega-capitalization stocks, such as Microsoft and America

Online. An astonishing fact: the 100 largest stocks in the S&P 500 provided 93%
of the Index's return in the first calendar quarter of 1999.

         For the six months ended April 30, 1999, John Hancock Large Cap Growth
Fund posted total returns of 24.37%, 23.93% and 23.89% for Class A, Class B and
Class C shares, respectively, at net asset value. This return compares with the
23.07% return of the average growth fund, according to Lipper, Inc.1 Keep in
mind that your net asset value return will be different from the Fund's stated
performance if you were not invested in the Fund for the entire period and did
not reinvest all distributions. Longer-term performance information can be found
on pages six and seven.

Shift toward accelerated earnings growth

In our last report, we discussed how we had targeted companies exhibiting
resilient earnings growth. That proved to be a profitable strategy

last summer, given the uncertainty about a global recession and extreme
volatility at that time.

         Early in fiscal 1999, as recession fears dissipated and markets settled
down, we shifted our focus to companies demonstrating accelerating earnings
growth. We did so believing that the dramatic change in investor psychology,
combined with the strong fundamentals of the U.S. economy -- high productivity
and low interest rates, inflation and unemployment -- bode well for companies in
certain industries that have the ability to grow their earnings more rapidly
than traditional stable-growth players. Our prime targets were companies that
have always exhibited consistent earnings growth, but where we believed there
was some catalyst, such as increased product demand, a new market or the
selling-off of marginal business operations, that would accelerate their
earnings growth potential.

Financial and telecom exposure increased

Three industry sectors that have accelerated earnings growth potential are
technology, telecommunications and finance, and the Fund benefited from our
increased emphasis on stocks in these sectors. Within the first few months of
fiscal 1999, we decreased the Fund's exposure to health-care stocks and switched
our concentration within the retail arena as selected stable-growth holdings
reached our near-term price objectives. We sold many issues at considerable
profit, including such noteworthy names as Warner-Lambert, Abbott Laboratories,
Colgate-Palmolive, Walgreen and Kroger. We moved money instead into such
retailers as Wal-Mart Stores, Costco, Lowe's and Home Depot, which stand to
benefit from a robust employment market, subdued inflation, the current

import/export picture and a strong housing market.

         In keeping with our accelerated earnings focus, we redirected our
attention within the technology arena from software to hardware firms,
increasing the Fund's position in companies such as EMC Corp. and adding
companies like Sun Microsystems. With telecommunications, we either added to, or
initiated positions in, such names as MCI WorldCom, Lucent Technologies, Tellabs
and Sprint.

         Financial stocks garnered our attention after being beaten down in
price during last year's global turmoil. Favorable demographics and market
trends give the sector strong rebound potential with the prospect of higher
earnings-per-share growth. We increased the Fund's weighting in financial
intermediaries, adding stakes in American Express, Citigroup, Bank of America,
Merrill Lynch and Providian Financial. Brisk merger and acquisition activity
across the industry should also give an upward bias to stock prices.


Select Industrials

In response to a broadening of the market late in the period, we purchased
several large growth conglomerates that are positioned to capitalize on the
resiliency of the U.S. economy and rebounding world economies. New holdings
include Textron, AlliedSignal and United Technologies -- all of which look
extremely attractive on a risk/reward basis given their proven ability to adapt
to changing market environments.

Outlook

We approach the final months of 1999 with a positive view, although we are not
without caution, given the market's recent preference for more economically
sensitive value stocks over certain of the growth stocks that have led the
market in the recent past. While we make no guarantees, our research suggests
that the U.S. economy should continue to post strong growth with no inflationary
forces on the near-term horizon. This should allow corporate earnings to remain
positive, particularly as the economies of Asia have begun to stabilize and
recover. While this may result in a more favorable environment than the past two
years for economically sensitive value stocks, it is also a great environment to
continue investing in growth stocks, especially those with international
customers and operations.

"...a positive view, although we are not without caution..."

                             A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Large Cap Growth Fund.  Total return measures
the change in value of an investment  from the beginning to the end of a period,
assuming all  distributions  were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 5%. Class B performance reflects a maximum contingent deferred sales
charge (maximum 5% and declining to 0% over six years). Class C performance
includes a contingent deferred sales charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

                   John Hancock Funds - Large Cap Growth Fund

(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Investment Trust III (the "Trust") is an open-end management
investment company, registered under the Investment Company Act of 1940. The
Trust consists of five series: John Hancock Large Cap Growth Fund (the "Fund"),
John Hancock Global Fund, John Hancock Short-Term Strategic Income Fund, John
Hancock Mid Cap Growth Fund and John Hancock International Fund. Prior to June
1, 1999, the Fund was known as John Hancock Growth Fund and the John Hancock Mid
Cap Growth Fund was known as John Hancock Special Opportunities Fund. The other
four series of the Trust are reported in separate financial statements. The
investment objective of the Fund is to seek long-term capital appreciation.

         The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that certain expenses, subject to the approval of the Trustees, may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission and the Internal Revenue
Service. Shareholders of a class which bears distribution and service expenses
under terms of a distribution plan have exclusive voting rights to that
distribution plan.

Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement transaction. Aggregate
cash balances are invested in one or more repurchase agreements, whose
underlying securities are obligations of the U.S. government and/or its
agencies. The Fund's custodian bank receives delivery of the underlying
securities for the joint account on the Fund's behalf. The Adviser is
responsible for ensuring that the agreement is fully collateralized at all
times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis for both financial
reporting and federal income tax purposes.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required.

DIVIDENDS, INTEREST AND DISTRIBUTIONS Dividend income on investment securities
is recorded on the ex-dividend date. Interest income on investment securities is
recorded on the accrual basis. Foreign income may be subject to foreign
withholding taxes, which are accrued as applicable.

         The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the relative net assets of the respective classes. Distribution
and service fees, if any, are calculated daily at the class level based on the
appropriate net assets of each class and the specific expense rate(s) applicable
to each class.

==========================NOTES TO FINANCIAL STATEMENTS=========================

                   John Hancock Funds - Large Cap Growth Fund

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative size of the funds.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. Effective March 12, 1999,
the Fund entered into a syndicated line of credit agreement with various banks,
and the agreements previously in effect were terminated. This agreement enables
the Fund to participate with other funds managed by the Advisor in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The
maximum loan balance outstanding during the period amounted to $6,579,000. The
annualized interest rate charged during the period ranged from 5.375% thru
5.625%. At April 30, 1999, the borrowings outstanding amounted to $6,271,000.

NOTE B -
MANAGEMENT FEE AND TRANSACTIONS WITH
AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of: (a) 0.75% of the first $750,000,000 of the
Fund's average daily net asset value and (b) 0.70% of the Fund's average daily
net asset value in excess of $750,000,000.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
April 30, 1999, net sales charges received with regard to sales of Class A
shares amounted to $305,858. Out of this amount, $39,847 was retained and used
for printing prospectuses, advertising, sales literature and other purposes,
$152,131 was paid as sales commissions to unrelated broker-dealers and $113,880
was paid as sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. The Adviser's indirect parent, John Hancock Mutual Life
Insurance Company ("JHMLICo"), is the indirect sole shareholder of Signator
Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended April 30, 1999,
contingent deferred sales charges amounted to $277,134.

         Class C shares which are redeemed within one year of purchase will be
subject to a contingent deferred sales charge ("CDSC") at a rate of 1.00% of the
lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSC are paid to
JH Funds and are used in whole or in part to defray its expenses related to
providing distribution related services to the Fund in connection with the sale
of Class C shares. For the period ended April 30, 1999, there were no contingent
deferred sales charges.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.30% of Class A average daily

==========================NOTES TO FINANCIAL STATEMENTS=========================

                   John Hancock Funds - Large Cap Growth Fund

net assets and 1.00% of Class B and Class C average daily net assets to
reimburse JH Funds for its distribution and service costs. Up to a maximum of
0.25% of such payments may be service fees as defined by the amended Rules of
Fair Practice of the National Association of Securities Dealers. Under the
amended Rules of Fair Practice, curtailment of a portion of the Fund's 12b-1
payments could occur under certain circumstances.

         The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

         The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Edward J. Boudreau, Jr., Mr. Stephen L. Brown, Ms. Anne C. Hodsdon
and Mr. Richard S. Scipione are directors and/or officers of the Adviser and/or
its affiliates, as well as Trustees of the Fund. The compensation of
unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect
to defer, for tax purposes, their receipt of this compensation under the John
Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments
into other John Hancock funds, as applicable, to cover its liability for the
deferred compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The deferred
compensation liability and the related other asset are always equal and are
marked to market on a periodic basis to reflect any income earned by the
investment as well as any unrealized gains or losses. At April 30, 1999, the
Fund's investments to cover the deferred compensation liability had unrealized
appreciation of $2,782.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than obligations of the
U.S. government and its agencies and short-term obligations, during the period
ended April 30, 1999, aggregated $765,383,107 and $760,494,076, respectively.

         The cost of investments owned at April 30, 1999 for federal income tax
purposes was $555,885,940. Gross unrealized appreciation and depreciation of
investments aggregated $186,033,952 and $6,730,510, respectively, resulting in
net unrealized appreciation of $179,303,442.

NOTE D -
REORGANIZATION

On November 12, 1997, the shareholders of John Hancock Disciplined Growth Fund
(JHDGF) and John Hancock Discover Fund (JHDF) approved a plan of reorganization
between JHDGF and the Fund and JHDF and the Fund, providing for the transfer of
substantially all of the assets and liabilities of JHDGF and JHDF to the Fund in
exchange solely for Class A and Class B shares of the Fund. The acquisition of
JHDGF was accounted for as a tax free exchange of 1,825,089 Class A shares and
5,012,295 Class B shares of the Fund (valued at $38,166,628 and $101,229,305,
respectively) for the 2,318,348 Class A shares and 6,305,496 Class B shares of
JHDGF, including $42,164,993 of unrealized appreciation, after the close of
business at December 5, 1997. The acquisition of JHDF was accounted for as a tax
free exchange of 2,067,272 Class A shares and 4,467,464 Class B shares of the

Class A shares and 5,636,912 Class B shares of JHDF, including $31,282,553 of
unrealized appreciation, after the close of business at December 5, 1997. The
aggregate net assets of JHDGF, JHDF and the Fund were $139,395,933, $133,457,006
and $350,721,840, respectively, immediately before the acquisition.

===============================CHAIRMAN'S MESSAGE===============================

DEAR FELLOW SHAREHOLDERS:

The Year 2000 is fast approaching and people around the world are getting ready
to celebrate this historic transition to a new millennium. At John Hancock
Funds, we share the excitement, but we aren't popping the champagne corks just
yet. Rather, we are staying on the course that we set more than two years ago to
ensure that the transition to a new millennium is a smooth one for our
shareholders.

As many already know, the Year 2000 has created more than the prospect of New
Year's festivities of epic proportions. It has also presented the world with a
challenge: making sure that older computers, and any equipment powered by
computer chips, can properly read and process the date "00" as 2000, not 1900.
Much has been written about how the world will weather the change. Some view it
as a non-event, while others see the potential for disruptions. How much
disruption, and for how long, depends on whom you talk to.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief Executive
Officer, flush right next to second paragraph.]
- --------------------------------------------------------------------------------

As a company, we recognize that the Year 2000 ("Y2K") phenomenon is an important
issue to be dealt with and we have made it a top priority. Two years ago, John
Hancock Funds put a full-time team of experts on the case and established a
company-wide program to evaluate all computer applications and to modify or
replace those that needed changing.

These modifications and replacements are nearly done, and the tests of all our
systems are on schedule for completion by the end of July. The rest of 1999 will
be spent testing with our business partners and continuing to participate in
industry testing. We have also established additional contingency plans beyond
our regular ones to prepare for any challenges that the Year 2000 might present.
In the end, John Hancock will spend approximately $90-$95 million to ensure we
make a successful transition to the Year 2000.

Throughout 1999, each of our quarterly "Fundamentals" newsletters is featuring
articles with more detailed information on Y2K matters of importance to our
shareholders. I encourage you to read them, or contact one of our Customer
Service Representatives at 1-800-225-5291 for another copy. For your own peace
of mind, we also recommend that you save your 1999 statements, especially those
you receive between October and December, so that you are able to check them
against the first one you receive in 2000. It's a measure of prudence, not
panic. Good record keeping is part of good planning.

No one knows how the dawning of the new millennium will unfold. Although we
cannot make any ironclad assurances, we are confident that the steps we have
taken will provide shareholders with as smooth a transition as possible. Once
that occurs, we will happily raise our glasses to toast the New Year, future
prosperity and our hopes to serve you well into the 2000's.

Sincerely,

/s/Edward J. Boudreau, Jr.

            Foreign stock markets advance as global turmoil subsides
            --------------------------------------------------------

Overseas markets gained ground over the last six months, as last summer's global
economic turmoil began to subside. The move up was volatile, however, while
investors sorted through the economic developments and market leadership changed
hands. Perhaps the biggest story during the period was the resurgence in March
and April of Japan and the recession ravaged emerging Asian and Latin American
stock markets. In Japan, foreign investors long underweighted in the second
largest market began pouring money back in after a bank rescue program was
implemented and several large corporate restructurings were announced.

         Brazil's ability to control the effects of its currency's devaluation
in January was the spark for renewed investor confidence that emerging markets
worldwide were coming out of last summer's woods. A strong U.S. economy and
stock market, and rising commodity prices also helped the commodity-dependent
emerging markets of Latin America stage their dramatic rebound. The rally was
still not enough, however, to bring them back to their levels of a year ago.
Europe, which had dominated overseas markets last year, took a breather in the
last several months because of a slowdown in economic growth and the unexpected
decline in value of the new euro common currency since its January 1 debut.

Stability: A mixed blessing

For the six months ended April 30, 1999, John Hancock International Fund's Class
A, Class B and Class C shares posted total returns of

13.62%, 13.22% and 13.22%, respectively, at net asset value. By comparison, the
Morgan Stanley Capital International (MSCI) All Country World Free Ex-U.S. Index
returned 17.17% and the average international fund returned 15.11%, according to
Lipper, Inc.1 Keep in mind that your net asset value return will be different
from the Fund's performance if you were not invested in the Fund for the entire
period and did not reinvest all distributions. Historical performance
information can be found on pages six and seven.

         Given the fluctuating world markets over the last year, we sought to
maintain a portfolio that represented stability in a volatile world. As a
result, we kept an overweighting in Europe and in the blue-chip names. While
this helped the Fund in the first half of the period, it detracted from our
performance in 1999, when Europe's economic growth slowed and the value of the
euro fell by 12% versus the dollar. At the sector

level, our overweighting in European utility, food and household product
companies such as Danone and Nestle held us back. Food companies were hurt by
their exposure to slowing emerging markets, and utility companies lagged when
good economic news sent investors into less defensive sectors.

Europe stays overweighted

Nevertheless, we are maintaining an overweighting in Europe, because we still
believe in the long-term opportunities stemming from corporate restructuring.
Indeed our European companies involved in restructurings or mergers continued to
be our top performers. These included Royal Philips Electronics, Mannesmann and
Vodafone. Our top holding, Nokia, was also our top performer, given its dominant
position in the fast-growing cellular phone market. We pared our European
holdings slightly to take advantage of opportunities in Japan and to move out of
weaker markets. While we still like France, we slightly reduced our
overweighting there, and moved out of Belgium's more defensive utility
companies. We also cut our stake in Germany, given its heavy emphasis on
manufacturing and exports, which could be stung by the Continent's slowdown.
That said, we have increased our stake in the U.K. because of signs of a growing
economy and the enhanced prospects of its joining the European commission, which
bodes well for lower interest rates.

Make room for Japan, Hong Kong

Following our cautious approach, we increased our stake in Japan gradually over
the period, yet we still moved from an 8% position last November to 20% of the
Fund's net assets by the end of April, through a combination of additional
purchases and good performance. Announcements

of several important corporate restructurings, including Fund holdings Sony and
NTT Data Corp., suggest that Japan is finally moving in the right direction by
placing more emphasis on shareholder value. We increased our stake in these and
other companies proactively pursuing restructurings. We also upped our holdings
in financial stocks, introducing a position in Sakura Bank and adding to our
positions in Bank of Tokyo-Mitsubishi and Nomura Securities, given the positive
implications of the bank recapitalization program. Another sector we targeted
was housing and construction, including Daiwa House Industry and Sekisui House,
since they are benefiting from government efforts to stimulate the economy.

         During the period, we re-established an underweighted 1% position in
Hong Kong, with the purchase of several blue-chip real estate and conglomerate
companies that are representative of the market. We are returning slowly to the
emerging markets, only after careful analysis and deliberation. This period, we
re-entered Brazil with our purchase of its high-quality Telecomunicacoes
Brasileiras communications company.

Positive outlook

Our optimism is growing about the prospects for international equities.
Better-than-expected world economic growth and the re-emergence of Asia and the
emerging markets are bolstering our enthusiasm. We will maintain a strong
presence in Europe, where we see the recent pullback as simply a normal market
correction following a period of sustained strength. Our belief in this region
has been reinforced by the European Central Bank's recent interest-rate cuts and
by current economic forecasts of stronger growth later this year. Now that we
have risen to a more average weighting in Japan, we will keep it fairly steady,
with a diverse portfolio that emphasizes companies that are restructuring or
will benefit from any domestic economic recovery. In Latin America, it appears
the economic slowdown will be less pronounced than expected. This, plus the
speed of reforms taking place there and in Asia, leaves us more favorably
inclined toward these markets.

- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock International Fund. Total return measures the
change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 5%. Class B performance reflects a maximum contingent deferred sales
charge (maximum 5% and declining to 0% over six years). Class C performance
includes a contingent deferred sales charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus for a discussion of the risks associated with international
investing, including currency and political risks and differences in accounting
standards and financial reporting, before you invest or send money.

Notes to Performance

(1) Effective January 3, 1994, the Adviser has temporarily voluntarily
    undertaken to limit the Fund's expenses, including the management fee
    (but not including the transfer agent fee and 12b-1 fee) to 0.90% of
    the Fund's daily net asset value. Without the limitations of expenses,
    the average annual total return for the one-year period, five-year
    period and since inception would have been (2.54%), 1.74% and 0.23% for
    Class A shares and (3.03%), 1.69% and 0.33% for Class B shares. The
    cumulative total return since inception would have been (0.72%) for
    Class C shares.

                    John Hancock Funds - International Fund



(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Investment Trust III (the "Trust") is a diversified open-end
management investment company, registered under the Investment Company Act of
1940. The Trust consists of five series: John Hancock International Fund (the
"Fund"), John Hancock Global Fund, John Hancock Large Cap Growth Fund, John
Hancock Mid Cap Growth Fund and John Hancock Short-Term Strategic Income Fund.
Prior to June 1, 1999, John Hancock Large Cap Growth Fund was known as John
Hancock Growth Fund and John Hancock Mid Cap Growth Fund was known as John
Hancock Special Opportunities Fund. The other four series of the Trust are
reported in separate financial statements. The investment objective of the Fund
is long-term growth of capital.

         The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that certain expenses, subject to the approval of the Trustees, may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission and the Internal Revenue
Service. Shareholders of a class which bears distribution and service expenses
under terms of a distribution plan have exclusive voting rights to that
distribution plan.

         Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value. All portfolio
transactions initially expressed in terms of foreign currencies have been
translated into U.S. dollars as described in "Foreign Currency Translation"
below.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. Aggregate cash balances
are invested in one or more repurchase agreements, whose underlying securities
are obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

         Capital gains realized on some foreign securities are subject to
foreign taxes and are accrued, as applicable.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Dividend income on investment securities
is recorded on the ex-dividend date or, in the case of some foreign securities,
on the date thereafter when the Fund identifies the dividend. Interest income on
investment securities is recorded on the accrual basis. Foreign income may be
subject to foreign withholding taxes, which are accrued as applicable.

         The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

CLASS ALLOCATIONS Income, common expenses, and realized and unrealized gains
(losses) are calculated at the Fund level and allocated daily

                                       18

===========================NOTES TO FINANCIAL STATEMENTS========================

                    John Hancock Funds - International Fund


to each class of shares based on the appropriate net assets of the respective
classes. Distribution and service fees if any, are calculated daily at the class
level based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative sizes of the funds.

ORGANIZATION EXPENSES Expenses incurred in connection with the organization of
the Fund have been capitalized and are being charged to the Fund's operations
ratably over a five-year period that commenced with the investment operations of
the Fund.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. Effective March 12, 1999,
the Fund entered into a syndicated line of credit agreement with various banks,
and the agreements previously in effect were terminated. This agreement enables
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the period ended April 30, 1999.

SECURITIES LENDING The Fund may lend its securities to certain qualified brokers
who pay the Fund negotiated lender fees. These fees are included in interest
income. The loans are collateralized at all times with cash or securities with a
market value at least equal to the market value of the securities on loan. As
with other extensions of credit, the Fund may bear the risk of delay of the
loaned securities in recovery or even loss of rights in the collateral should
the borrower of the securities fail financially. At April 30, 1999, the Fund
loaned securities having a market value of $2,800,984 collateralized by cash and
securities in the amount of $2,918,718. The cash portion of the collateral was
invested in a short-term instrument.

FOREIGN CURRENCY TRANSLATION All assets and liabilities initially expressed in
terms of foreign currencies are translated into U.S. dollars based on London
currency exchange quotations as of 5:00 p.m., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain/(loss) on investments are
translated at the rates prevailing at the dates of the transactions.

         The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss from
investments.

         Reported net realized foreign exchange gains or losses arise from sales
of foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains or losses arise from changes in the
value of assets and liabilities other than investments in securities at fiscal
year end, resulting from changes in the exchange rate.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS The Fund may enter into forward
foreign currency exchange contracts as a hedge against the effect of
fluctuations in currency exchange rates. A forward foreign currency exchange
contract involves an obligation to purchase or sell a specific currency at a
future date at a set price. The aggregate principal amounts of the contracts are
marked to market daily at the applicable foreign currency exchange rates. Any
resulting unrealized gains and losses are included in the determination of the
Fund's daily net assets. The Fund records realized gains and losses at the time
the forward foreign currency contract is closed out or offset by a matching
contract. Risks may arise upon entering these contracts from potential inability
of


                                       19

counterparties to meet the terms of the contract and from unanticipated
movements in the value of a foreign currency relative to the U.S. dollar.

         These contracts involve market or credit risk in excess of the
unrealized gain or loss reflected in the Fund's Statement of Assets and
Liabilities. The Fund may also purchase and sell forward contracts to facilitate
the settlement of foreign currency denominated portfolio transactions, under
which it intends to take delivery of the foreign currency. Such contracts
normally involve no market risk if they are offset by the currency amount of the
underlying transaction.

         At April 30, 1999, the Fund had no open forward foreign currency
exchange contracts.

NOTE B -
MANAGEMENT FEE AND TRANSACTIONS
WITH AFFILIATES AND OTHERS

The Adviser is solely responsible for advising the Fund with respect to
investments in the United States and Canada. The Fund and the Adviser also have
a sub-investment management contract with John Hancock Advisers International
Limited (the "Sub-Adviser"), a wholly owned subsidiary of the Adviser, under
which the Sub-Adviser, subject to the review of the Trustees and overall
supervision of the Adviser, provides the Fund with investment management
services and advice with respect to the portion of the Fund's assets invested in
countries other than the United States and Canada.

         Under the present investment management contract, the Fund pays a
monthly management fee to the Adviser for a continuous investment program
equivalent, on an annual basis, to the sum of (a) 1.00% of the first
$250,000,000 of the Fund's average daily net asset value, (b) 0.80% of the next
$250,000,000, (c) 0.75% of the next $250,000,000 and (d) 0.625% of the Fund's
average daily net asset value in excess of $750,000,000. The Adviser pays the
Sub-Adviser a fee equivalent, on an annual basis, to the sum of (a) 0.70% of the
first $200,000,000 of the Fund's average daily net asset value and (b) 0.6375%
of the Fund's average daily net asset value in excess of $200,000,000. The Fund
is not responsible for the payment of the Sub-Adviser's fee.

         The Adviser has agreed to limit Fund expenses, including the management
fee (but not including transfer agent and 12b-1 expenses), to 0.90% of the
Fund's average daily net assets. Accordingly, the reduction in the Adviser's fee
amounted to $154,298 for the period ended April 30, 1999. The Adviser reserves
the right to terminate this limitation in the future.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
April 30, 1999, net sales charges received with regard to sales of Class A
shares amounted to $10,025. Out of this amount, $1,218 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $6,462
was paid as sales commissions to unrelated broker-dealers and $2,345 was paid as
sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. The Adviser's indirect parent, John Hancock Mutual Life
Insurance Company ("JHMLICo"), is the indirect sole shareholder of Signator
Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended April 30, 1999,
contingent deferred sales charges paid to JH Funds amounted to $54,899.

         Class C shares which are redeemed within one year of purchase will be
subject to a CDSC at a rate of 1.00% of the lesser of the current market value
at the time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from the CDSC are paid to JH Funds and are used in whole or
in part to defray its expenses for providing distribution related services to
the Fund in connection with the sale of Class C shares. For the period ended
April 30, 1999, contingent deferred sales charges paid to JH Funds amounted to
$480.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution

Plan with respect to Class A, Class B and Class C pursuant to Rule 12b-1 under
the Investment Company Act of 1940. Accordingly, the Fund will make payments to
JH Funds for distribution and service expenses, at an annual rate not to exceed
0.30% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. Up to a maximum of 0.25% of such payments may be service fees as defined
by the amended Rules of Fair Practice of the National Association of Securities
Dealers. Under the amended Rules of Fair Practice, curtailment of a portion of
the Fund's 12b-1 payments could occur under certain circumstances.

         The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

         The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Edward J. Boudreau, Jr., Mr. Stephen L. Brown, Ms. Anne C. Hodsdon
and Mr. Richard S. Scipione are directors and/or officers of the Adviser and/or
its affiliates, as well as Trustees of the Fund. The compensation of
unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect
to defer for tax purposes their receipt of this compensation under the John
Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments
into other John Hancock funds, as applicable, to cover its liability for the
deferred compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The deferred
compensation liability and the related other asset are always equal and are
marked to market on a periodic basis to reflect any income earned by the
investment as well as any unrealized gains or losses. At April 30, 1999, the
Fund's investments to cover the deferred compensation liability had unrealized
appreciation of $50.


NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than obligations of the
U.S. government and its agencies and short-term securities, during the period
ended April 30, 1999, aggregated $5,669,471 and $1,220,818, respectively. There
were no purchases or sales of obligations of the U.S. government and its
agencies during the period ended April 30, 1999.

         The cost of investments owned at April 30, 1999 (including short-term
investments) for federal income tax purposes was $16,794,639. Gross unrealized
appreciation and depreciation of investments aggregated $2,279,246 and $540,254,
respectively, resulting in net unrealized appreciation of $1,738,992.

==============================CHAIRMAN'S MESSAGE================================

DEAR FELLOW SHAREHOLDERS:

The Year 2000 is fast approaching and people around the world are getting ready
to celebrate this historic transition to a new millennium. At John Hancock
Funds, we share the excitement, but we aren't popping the champagne corks just
yet. Rather, we are staying on the course that we set more than two years ago to
ensure that the transition to a new millennium is a smooth one for our
shareholders.

As many already know, the Year 2000 has created more than the prospect of New
Year's festivities of epic proportions. It has also presented the world with a
challenge: making sure that older computers, and any equipment powered by
computer chips, can properly read and process the date "00" as 2000, not 1900.
Much has been written about how the world will weather the change. Some view it
as a non-event, while others see the potential for disruptions. How much
disruption, and for how long, depends on whom you talk to.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief Executive
Officer, flush right next to second paragraph.]
- --------------------------------------------------------------------------------

As a company, we recognize that the Year 2000 ("Y2K") phenomenon is an important
issue to be dealt with and we have made it a top priority. Two years ago, John
Hancock Funds put a full-time team of experts on the case and established a
company-wide program to evaluate all computer applications and to modify or
replace those that needed changing.

These modifications and replacements are nearly done, and the tests of all our
systems are on schedule for completion by the end of July. The rest of 1999 will
be spent testing with our business partners and continuing to participate in
industry testing. We have also established additional contingency plans beyond
our regular ones to prepare for any challenges that the Year 2000 might present.
In the end, John Hancock will spend approximately $90-$95 million to ensure we
make a successful transition to the Year 2000.

Throughout 1999, each of our quarterly "Fundamentals" newsletters is featuring
articles with more detailed information on Y2K matters of importance to our
shareholders. I encourage you to read them, or contact one of our Customer
Service Representatives at 1-800-225-5291 for another copy. For your own peace
of mind, we also recommend that you save your 1999 statements, especially those
you receive between October and December, so that you are able to check them
against the first one you receive in 2000. It's a measure of prudence, not
panic. Good record keeping is part of good planning.

No one knows how the dawning of the new millennium will unfold. Although we
cannot make any ironclad assurances, we are confident that the steps we have
taken will provide shareholders with as smooth a transition as possible. Once
that occurs, we will happily raise our glasses to toast the New Year, future
prosperity and our hopes to serve you well into the 2000's.

Sincerely,

/s/Edward J. Boudreau, Jr.

              Healthy economy drives U.S. stocks to strong finish
              ---------------------------------------------------

Effective June 1, 1999, John Hancock Special Opportunities Fund was renamed John
Hancock Mid Cap Growth Fund to better describe how the Fund invests.

U.S. stocks began to rebound last fall, following the Federal Reserve's decision
to  cut  short-term  interest  rates.  Strong  economic  growth,  continued  low
inflation  levels and stable  interest  rates kept stocks  climbing into the new
year.  Signs that the economy might be weakening caused the market to stumble in
February.  But the market  regained  its momentum in March and April as economic
growth  remained  steady  and  most  corporations  reported  high  first-quarter
profits.  Reassured  investors began expanding their investment  horizons beyond
the  select  group of  large-company  stocks  that had led the  market's  uphill
charge.  This helped the Russell  Midcap  Growth  Index  return  27.38%  between
October  31,  1998 and April 30,  1999.

Performance and strategy review

John Hancock Mid Cap Growth Fund's Class A, Class B and Class C shares returned
23.71%, 23.28% and 23.17%, respectively, at net asset value, for the six months
ended April 30, 1999. For the same period, the average mid-cap fund gained
23.15%, according to Lipper, Inc.1 Keep in mind that your net asset value return
will differ from the Fund's performance if you were not invested in the Fund for
the entire period and did not reinvest all distributions. Please see pages six
and seven for longer-term performance information.

         Strong stock selection helped us keep pace with other mid-cap funds,
many of which invested a portion of their assets in top-performing large-company
stocks. By contrast, the Fund maintained its strategy of focusing on true
mid-cap stocks - although during the period we did shift some of our investments
toward the larger end of the mid-cap market.

Technology winners

Some of the Fund's best performers were technology stocks, which represented 44%
of net assets. In particular, we invested heavily in telecommunications
equipment and service companies - many of which are involved in building
fiber-optic networks for Internet as well as data transmission services.
NEXTLINK Communications, a company that is building networks in major
metropolitan areas and offers better service than the local Bell operating
companies, saw its stock gain 186% during the

period. Similarly, the stock of Global Crossing, a company positioned to offer
contiguous service from New England across the Atlantic and into Europe, rose
nearly 300% between October 31, 1998, and the time we sold it in March. In its
place, we bought Frontier Corp., a U.S. telecommunications firm that Global is
buying. Frontier's stock, which is tied to Global's through the acquisition, was
available at a discount. Other top performers included Ascend Communications, a
leading telecommunications equipment manufacturer that Lucent Technologies is
buying, and Qwest Communications International, a company that is laying a
fiber-optic network across the United States.

         Another area that boosted performance was Internet stocks. We started
building our stake in December, adding to it in February. By mid-April, our
Internet investments accounted for over 10% of net assets, including
well-recognized names like Yahoo! and Amazon.com. Prices on Internet stocks
climbed so high that we decided to lock in gains and trimmed our stake to about
4% by period end. Although we expect the Internet to be a vibrant force in the
economy, there will most likely be better buying opportunities ahead. Our
semiconductor stocks also appreciated nicely. The stock of Conexant Systems, a
leading supplier of semiconductors to the high-growth communications industry,
climbed 152% from the time we bought it in January through the end of April.
During the period, we also bought shares in Best Buy and Circuit City Stores,
retailers that sell technology products like PCs and digital VCRs. These stocks
did well amidst strong consumer spending. Finally, core holdings like Lexmark
International Group, which makes low-cost printers, and EMC Corp., a
manufacturer of data storage

devices, delivered returns in excess of 75% for the period.

Finance and health-care cuts

We trimmed our finance stake to about 15% of net assets, paring our investments
in the banking and insurance sectors while adding to financial services. Our
biggest new investments were in brokerage stocks, which have benefited from the
rising market as well as increased on-line trading. Among the names we added
were market leaders like Charles Schwab, as well as Donaldson, Lufkin & Jenrette
and E*TRADE Group. We also cut back on our investment in health-care stocks,
especially service providers, because of concerns that tightened Medicare
reimbursement policies would hurt profit margins. By late April, however, these
stocks had declined to such low levels that we started adding selectively to
names like Omnicare, a company that supplies drugs to nursing homes whose
prospects remained strong. We also added to Guidant, a medical device
manufacturer that has developed a superior stent with the potential to cut down
on open-heart surgery by making it easier to open up blocked arteries.

Looking ahead

We remain cautiously optimistic about the stock market's prospects for several
reasons. Even if the market takes a breather or economic growth slows, the U.S.
economy will most likely remain healthy, inflation low and interest rates around
current levels. Year-end 1998 and first-quarter 1999 earnings were on target or
better than expected at most companies, reaffirming the strength of corporate
America. Economies in Brazil and Asia have begun to stabilize, while growth in
Europe appears to be accelerating modestly. All of this bodes well for stock
investors, especially those with a long-term investment horizon who are willing
to ride out near-term volatility. We're particularly optimistic about the
mid-cap sector of the market, which continues to offer strong earnings growth
prospects and attractive valuations relative to larger-cap names.

A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Mid Cap Growth Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 5%. Class B performance reflects a maximum contingent deferred sales
charge (maximum 5% and declining to 0% over six years). Class C performance
includes a contingent deferred sales charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

The charts on the right show how much a $10,000 investment in the John Hancock
Mid Cap Growth Fund would be worth, assuming all distributions were reinvested
for the period indicated. For comparison, we've shown the same $10,000
investment in both the Standard & Poor's 500 Stock Index and the Russell Midcap
Growth Index. The Standard & Poor's 500 Stock Index is an unmanaged index that
includes 500 widely traded common stocks and is a commonly used measure of stock
market performance. The Russell Midcap Growth Index is an unmanaged index that
contains those securities from the Russell Midcap Index with a
greater-than-average growth orientation. Past performance is not indicative of
future results.

The Statement of Changes in Net Assets shows how the value of the Fund's net
assets has changed since the end of the previous period. The difference reflects
earnings less expenses, any investment gains and losses, distributions paid to
shareholders and any increase or decrease in money shareholders invested in the
Fund. The footnote illustrates the number of Fund shares sold, reinvested and
repurchased during the last two periods, along with the corresponding dollar
value.

                    John Hancock Funds - Mid Cap Growth Fund

(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Investment Trust III is an open-end management investment company,
registered under the Investment Company Act of 1940. The Trust consists of five
series: John Hancock Mid Cap Growth Fund (the "Fund"), John Hancock Global Fund,
John Hancock Short-Term Strategic Income Fund, John Hancock Large Cap Growth
Fund and John Hancock International Fund. Prior to June 1, 1999, the Fund was
known as John Hancock Special Opportunities Fund and the John Hancock Large Cap
Growth Fund was known as John Hancock Growth Fund. The other four series of the
Trust are reported in separate financial statements. The investment objective of
the Fund is long-term capital appreciation.

         The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that certain expenses, subject to the approval of the Trustees, may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission and the Internal Revenue
Service. Shareholders of a class which bears distribution and service expenses
under terms of a distribution plan have exclusive voting rights to that
distribution plan.

  Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value. All portfolio
transactions initially expressed in terms of foreign currencies have been
translated into U.S. dollars as described in "Foreign Currency Translation."

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement transaction. Aggregate
cash balances are invested in one or more repurchase agreements, whose
underlying securities are obligations of the U.S. government and/or its
agencies. The Fund's custodian bank receives delivery of the underlying
securities for the joint account on the Fund's behalf. The Adviser is
responsible for ensuring that the agreement is fully collateralized at all
times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis for both financial
reporting and federal income tax purposes. Capital gains realized on some
foreign securities are subject to foreign taxes and are accrued, as applicable.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, at April 30, 1999, the fund has $8,860,270 of
capital loss carryforwards available, to the extent provided by regulations, to
offset future net realized capital gains. If such carryforwards are used by the
Fund, no capital gain distributions will be made. The Fund's carryforwards
expire as follows: October 31, 1999 - $1,297,087, October 31, 2000 - $12,856,
October 31, 2001 - $3,094,744 and October 31, 2002 - $4,455,583. Availability of
a certain amount of loss carryforwards which were acquired on September 6, 1996
and December 16, 1994 in mergers, may be limited in a given year.

DIVIDENDS, INTEREST AND DISTRIBUTIONS Dividend income on investment securities
is recorded on the ex-dividend date or, in the case of some foreign securities,
on the date thereafter when the Fund is made aware of the dividend. Interest
income on investment securities is recorded on the accrual basis. Foreign income
may be subject to foreign withholding taxes, which are accrued as applicable.

         The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such

                    John Hancock Funds - Mid Cap Growth Fund

distributions are determined in conformity with income tax regulations, which
may differ from generally accepted accounting principles. Dividends paid by the
Fund with respect to each class of shares will be calculated in the same manner,
at the same time and will be in the same amount, except for the effect of
expenses that may be applied differently to each class.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the relative net assets of the respective classes. Distribution
and service fees, if any, are calculated daily at the class level based on the
appropriate net assets of each class and the specific expense rate(s) applicable
to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative size of the funds.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. Effective March 12, 1999,
the Fund entered into a syndicated line of credit agreement with various banks
and the agreements previously in effect were terminated. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund, based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the period ended April 30, 1999.

FOREIGN CURRENCY TRANSLATION All assets and liabilities initially expressed in
terms of foreign currencies are translated into U.S. dollars based on London
currency exchange quotations as of 5:00 p.m., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain/(loss) on investments are
translated at the rates prevailing at the dates of the transactions.

         The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss from
investments.

         Reported net realized foreign exchange gains or losses arise from sales
of foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains or losses arise from changes in the
value of assets and liabilities other than investments in securities at fiscal
year end, resulting from changes in the exchange rate.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS The Fund may enter into forward
foreign currency exchange contracts as a hedge against the effect of
fluctuations in currency exchange rates. A forward foreign currency exchange
contract involves an obligation to purchase or sell a specific currency at a
future date at a set price. The aggregate principal amounts of the contracts are
marked to market daily at the applicable foreign currency exchange rates. Any
resulting unrealized gains and losses are included in the determination of the
Fund's daily net assets. The Fund records realized gains and losses at the time
the forward foreign currency contract is closed out or offset by a matching
contract. Risks may arise upon entering these contracts from potential inability
of counterparties to meet the terms of the contract and from unanticipated
movements in the value of a foreign currency relative to the U.S. dollar.

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - Mid Cap Growth Fund


         These contracts involve market or credit risk in excess of the
unrealized gain or loss reflected in the Fund's Statement of Assets and
Liabilities. The Fund may also purchase and sell forward contracts to facilitate
the settlement of foreign currency denominated portfolio transactions, under
which it intends to take delivery of the foreign currency. Such contracts
normally involve no market risk if they are offset by the currency amount of the
underlying transaction.

         At April 30, 1999, there were no open forward foreign currency exchange
contracts.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative purposes and/or to hedge against the effects of
fluctuations in interest rates and other market conditions. Buying futures tends
to increase the Fund's exposure to the underlying instrument. Selling futures
tends to decrease the Fund's exposure to the underlying instrument or hedge
other Fund instruments. At the time the Fund enters into a financial futures
contract, it is required to deposit with its custodian a specified amount of
cash or U.S. government securities, known as "initial margin," equal to a
certain percentage of the value of the financial futures contract being traded.
Each day, the futures contract is valued at the official settlement price of the
board of trade or U.S. commodities exchange on which it trades. Subsequent
payments, known as "variation margin," to and from the broker are made on a
daily basis as the market price of the financial futures contract fluctuates.
Daily variation margin adjustments, arising from this "mark to market," are
recorded by the Fund as unrealized gains or losses.

         When the contracts are closed, the Fund recognizes a gain or loss.
Risks of entering into futures contracts include the possibility that there may
be an illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange.

         For federal income tax purposes, the amount, character and timing of
the Fund's gains and/or losses can be affected as a result of futures contracts.

         At April 30, 1999, there were no open positions in financial futures
contracts.

SHORT SALE POSITIONS The Fund, in "selling short," sells borrowed securities
which must at some date be repurchased and returned to the lender. The risk
associated with this practice is that, if the market value of securities sold
short increases, the Fund may realize losses upon repurchase at prices which may
exceed the prices used in determining the liability on the Statement of Assets
and Liabilities. Further, in unusual circumstances, the Fund may be unable to
repurchase securities to close its short positions except at prices above those
previously quoted in the market.

   At April 30, 1999, there were no open positions in short sales.

NOTE B -
MANAGEMENT FEE AND
TRANSACTIONS WITH AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of: (a) 0.80% of the first $500,000,000 of the
Fund's average daily net asset value, (b) 0.75% of the next $500,000,000 and (c)
0.70% of the Fund's average daily net asset value in excess of $1,000,000,000.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
April 30, 1999, net sales charges received with regard to sales of Class A
shares amounted to $39,917. Out of this amount, $6,296 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $628
was paid as sales commissions to unrelated broker-dealers and $32,993 was paid
as sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. The Adviser's indirect parent, John Hancock Mutual Life
Insurance Company ("JHMLICo"), is the indirect sole shareholder of Signator
Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the

time of redemption or the original purchase cost of the shares being redeemed.
Proceeds from the CDSC are paid to JH Funds and are used in whole or in part to
defray its expenses related to providing distribution related services to the
Fund in connection with the sale of Class B shares. For the period ended April
30, 1999, contingent deferred sales charges paid to JH Funds amounted to
$245,869.

         Class C shares which are redeemed within one year of purchase will be
subject to a contingent deferred sales charge ("CDSC") at a rate of 1.00% of the
lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSC are paid to
JH Funds and are used in whole or in part to defray its expenses related to
providing distribution related services to the Fund in connection with the sale
of Class C shares. For the period ended April 30, 1999, contingent deferred
sales charges paid to JH Funds amounted to $1,148.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.30% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. Up to a maximum of 0.25% of such payments may be service fees as defined
by the amended Rules of Fair Practice of the National Association of Securities
Dealers. Under the amended Rules of Fair Practice, curtailment of a portion of
the Fund's 12b-1 payments could occur under certain circumstances.

         The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

         The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Edward J. Boudreau, Jr., Mr. Stephen L. Brown, Ms. Anne C. Hodsdon
and Mr. Richard S. Scipione are directors and/or officers of the Adviser and/or
its affiliates, as well as Trustees of the Fund. The compensation of
unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect
to defer, for tax purposes, their receipt of this compensation under the John
Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments
into other John Hancock funds, as applicable, to cover its liability for the
deferred compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The deferred
compensation liability and the related other asset are always equal and are
marked to market on a periodic basis to reflect any income earned by the
investment as well as any unrealized gains or losses. At April 30, 1999, the
Fund's investments to cover the deferred compensation liability had unrealized
appreciation of $1,612.
