===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:

I am delighted that one of my first official duties at John Hancock Funds is to
welcome you to the New Millennium! I wish you all the best for a century filled
with momentous occasions.

Every New Year, of course, provides us with a built-in opportunity to make new
resolutions, or re-commit to old ones. It seems fitting, therefore, that this
special New Year 2000 coincides with a very important, although certainly less
exotic, event.

Starting last October, personalized Social Security statements are being sent to
125 million workers over age 25, showing estimates of the retirement, disability
and survivor benefits that they and their families are eligible to receive now
and in the future.

The statements, to be sent out annually, will provide people with a glimpse of
what they can expect from the government when they retire. This should be
comforting to those who feared that Social Security wouldn't be there for them
at all. But many people also already know that government benefits will only
fulfill a small piece of their retirement needs.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman and Chief Executive Officer,
flush right next to fourth paragraph.]
- --------------------------------------------------------------------------------

The best thing about this massive mailing is that it can serve as a wake-up call
to encourage families to focus more on planning for their financial future.

When you receive your statement, expected to be within three months of your next
birthday, we urge you to read it carefully for accuracy, making sure your annual
earnings history and amounts you have contributed over the years are correct.
Keep in mind that the estimated benefits are precisely that, and that rules and
regulations may change by the time you retire. Also remember that they are not
inflation adjusted, so it would be unrealistic to expect them to have the same
purchasing power in the future as they would today.

We also encourage you to use this mailing as a reason to contact your investment
professional, or to select one if you are not working with somebody. He or she
can help you focus on establishing and maintaining a sound plan to achieve a
comfortable retirement. Together, you should make sure to maximize your
participation in tax-advantaged programs like IRAs and 401(k)s.

The stakes are too high to leave your retirement lifestyle to chance. Congress'
awareness-raising effort is commendable. The next step is yours. Mark the
beginning of the New Millennium by taking it.

Sincerely,


/s/ Maureen R. Ford

                                  John Hancock
                              Large Cap Growth Fund

          Last fiscal year of 20th century ends with substantial gains

We view fiscal 1999 as having two distinct phases. In the first six months of
the period, investors overcame their fears caused by last summer's near-global
financial meltdown. By April's end, however, the mood of the market had changed
to uncertainty. As it became clear that there was nascent global recovery,
leadership broadened to include economically sensitive value stocks,
small-capitalization companies and energy-related issues. This led to concerns
about an overheating domestic economy and the possibility of the Federal
Reserve's intervention to curtail inflation, both of which pushed interest rates
higher and increased market volatility. Economic growth continued to accelerate
and the Fed raised short-term interest rates twice over the summer. As the
second half of the fiscal year came to a close, the market had narrowed, with
select large-cap growth stocks again taking center stage, driving the market as
they have for much of the last three years.

Solid performance results

For the 12 months ended October 31, 1999, John Hancock Large Cap Growth Fund
returned a total of 27.58%, 26.70% and 26.72% for Class A, Class B and Class C
shares, respectively. These returns compare with the 25.67% return of the S&P
500 Index and the 29.12% 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.

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

Technology and telecom dominate

Throughout the period, we maintained a heavy weighting in technology-related and
communication services stocks, which include telecommunication equipment
companies and wireless service providers. In the year's first half, we
emphasized hardware firms, adding companies like Sun Microsystems and bolstering
our position in others, such as EMC. By midyear, valuations in the software
arena had reached extremely attractive levels as Y2K concerns grew. Believing
that fears were overdone, we selectively increased our exposure to certain
software companies, including BMC Software and Computer Associates
International, that are poised to resume their upward momentum once Y2K is
hurdled.

Expanded avenues of growth

The explosive popularity of the Internet and the revolution in how we work and
communicate with one another has succeeded in erasing the fine lines between
technology's sub-sectors, so that many companies offer tremendous growth
potential on several fronts. Portfolio holdings such as Cisco Systems and Lucent
Technologies are prime examples of companies benefiting from the expansion of
not only the Internet, but also global telecommunications. MCI WorldCom, Bell
Atlantic, Sprint PCS and Nextel Communications are communication service
providers whose avenues of growth are also rapidly expanding as deregulation
continues to exert a positive influence.

Renewed interest in pharmaceuticals

Early in the fiscal year, we decreased our exposure to health-care stocks --
pharmaceuticals in particular. Our decision proved advantageous as Medicare
reform and patent expiration concerns dampened the performance of many drug
stocks. For defensive and opportunistic reasons, however, we recently renewed
our interest in certain fundamentally sound companies, such as Schering-Plough,
Pharmacia & Upjohn and Warner-Lambert. Not only had their stock prices become
attractive, but the possibility of an economic slowdown should also create a
favorable backdrop for these stable-growth players.

Financial holdings pared

Financial stocks such as Providian, Wells Fargo, Bank of America, American
Express and Citigroup contributed significantly to the Fund's performance in the
early months of 1999. Despite the fact that the earnings of financial companies
are not as vulnerable to rising interest rates as is widely believed, many of
our holdings came under pressure as rates began to rise this past spring. By
August, we had halved the Fund's weighting in the financial arena to sidestep
the possibility of further downturns as rates continued to rise through period's
end. We've held on to a few sound bank and consumer

finance stocks, including Citigroup and Associates First Capital, believing that
once rates stabilize, investors will renew their interest in this sector. In
view of imminent financial reform legislation, which should lead to
consolidation, we recently added quality life insurer American General to the
portfolio.

Rotation in retail

The strength of the U.S. economy gave consumers confidence, and thereby many
retailers a strong boost this past year. Early on, we sold consumer staple
stocks such as Kroger, a supermarket retailer, to invest in more cyclically
oriented retailers that offered greater earnings and price appreciation
potential. Included in this category were Home Depot, Costco, Lowe's and
Wal-Mart Stores -- all of which experienced strong run-ups in price. By late
summer, the outlook for the economy pointed toward a slight slowdown and we
reduced or cut these positions to re-deploy assets back into the more defensive
consumer-staple sector. We re-introduced Kroger and added CVS and Safeway. In
hindsight, our move may have been a bit premature, as these stocks suffered
along with many others late in the period. However, business conditions at these
companies remain robust and we find their valuations compelling.

A tri-fold approach to fiscal 2000

Despite the advances of a narrow band of large-cap stocks, the average S&P 500
stock is currently down 25% from its high this past year. As a result, we enter
fiscal 2000 with many investment opportunities ahead. Selectivity, however, will
be the key, as these opportunities may not lie in the narrow band of stocks that
have dominated the market's performance this past year.

      We will continue to focus on technology-related companies that exhibit
strong secular growth potential both in the U.S. and abroad, regardless of
economic and market conditions.

      We will also keep our sights on companies that stand to benefit from the
recovery in the world's economies. These would be the multinational corporations
and diversified industrial firms that can participate in growth overseas and
thereby offer earnings stability should the economy slow at home.

      Finally, we believe a modest slowdown in the economy is likely in the
months ahead, whether or not the Fed chooses to increase short-term interest
rates again. As a result, we will look to further position part of the portfolio
a bit defensively by investing in more stable growth companies that investors
historically turn to during uncertain times.

"Selectivity, however, will be the key..."

                              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 the 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.

                    WHAT HAPPENED TO A $10,000 INVESTMENT...
- --------------------------------------------------------------------------------

The charts on the right show how much a $10,000 investment in the John Hancock
Large 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 the Standard & Poor's 500 Index. The Standard & Poor's 500 Index
is an unmanaged index that includes 500 widely traded common stocks and is a
commonly used measure of stock market performance. It is not possible to invest
in an index. Past performance is not indicative of future results.

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

                   John Hancock Funds - Large Cap Growth Fund

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 four series: John Hancock Large Cap Growth Fund (the "Fund"),
John Hancock Global Fund, John Hancock Mid Cap Growth Fund and John Hancock
International Fund. The other three 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.

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.

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

                   John Hancock Funds - Large Cap Growth 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 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 year amounted to $6,579,000. The
annualized interest rate charged during the year ranged from 5.375% through
5.625%. At October 31, 1999, there were no outstanding borrowings.

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 October 31, 1999, the Fund
loaned securities having a market value of $28,259,763 collateralized by
securities in the amount of $29,548,505.

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 year ended October
31, 1999, net sales charges received with regard to sales of Class A shares
amounted to $599,985. Out of this amount, $77,978 was retained and used for
printing prospectuses, advertising, sales literature and other purposes,
$266,548 was paid as sales commissions to unrelated broker-dealers and $255,459
was paid as sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. 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 year ended October 31, 1999,
contingent deferred sales charges amounted to $607,273.

      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 related to providing distribution related
services to the Fund in connection with the sale of Class C shares. For the year
ended October 31, 1999, contingent deferred sales charges amounted to $29.

      In addition, to reimburse JH Funds for the services it provides as
distributors 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

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

                   John Hancock Funds - Large Cap Growth Fund

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. A maximum of 0.25% of such payments may be
service fees as defined by the Conduct Rules of the National Association of
Securities Dealers. Under the Conduct Rules, 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,
accounting and legal services for the Fund. The compensation for the year 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. Maureen R. Ford,
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 through
December 31, 1999. 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. The investment had no impact on the operations of the Fund.

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 year
ended October 31, 1999, aggregated $1,401,862,406 and $1,358,911,682,
respectively.

      The cost of investments owned at October 31, 1999 (excluding the corporate
savings account) for federal income tax purposes was $652,965,739. Gross
unrealized appreciation and depreciation of investments aggregated $194,148,479
and $19,363,905, respectively, resulting in net unrealized appreciation of
$174,784,574.

NOTE D -
REORGANIZATION

On November 12, 1997, the shareholders of John Hancock Disciplined Growth Fund
(JHDGF) and John Hancock Discovery 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
Fund (valued at $43,231,211 and $90,225,795, respectively) for 2,567,733 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.

NOTE E -
RECLASSIFICATION OF ACCOUNTS

During the year ended October 31, 1999, the Fund has reclassified amounts to
reflect a decrease in accumulated net realized gain on investments of
$31,127,453, a decrease in accumulated net investment loss of $7,143,185 and an
increase in capital paid-in of $23,984,268. This represents the amount necessary
to report these balances on a tax basis, excluding certain temporary
differences, as of October 31, 1999. Additional adjustments may be needed in
subsequent reporting periods. These reclassifications, which have no impact on
the net asset value of the Fund, are primarily attributable to the treatment of
net operating losses in the computation of distributable income and capital
gains under federal tax rules versus generally accepted accounting priciples and
the Fund's use of the tax accounting practice known as equalization. The
calculation of net investment income per share in the financial highlights
excludes these adjustments.

===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:

I am delighted that one of my first official duties at John Hancock Funds is to
welcome you to the New Millennium! I wish you all the best for a century filled
with momentous occasions.

Every New Year, of course, provides us with a built-in opportunity to make new
resolutions, or re-commit to old ones. It seems fitting, therefore, that this
special New Year 2000 coincides with a very important, although certainly less
exotic, event.

Starting last October, personalized Social Security statements are being sent to
125 million workers over age 25, showing estimates of the retirement, disability
and survivor benefits that they and their families are eligible to receive now
and in the future.

The statements, to be sent out annually, will provide people with a glimpse of
what they can expect from the government when they retire. This should be
comforting to those who feared that Social Security wouldn't be there for them
at all. But many people also already know that government benefits will only
fulfill a small piece of their retirement needs.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman and Chief Executive Officer,
flush right next to fourth paragraph.]
- --------------------------------------------------------------------------------

The best thing about this massive mailing is that it can serve as a wake-up call
to encourage families to focus more on planning for their financial future.

When you receive your statement, expected to be within three months of your next
birthday, we urge you to read it carefully for accuracy, making sure your annual
earnings history and amounts you have contributed over the years are correct.
Keep in mind that the estimated benefits are precisely that, and that rules and
regulations may change by the time you retire. Also remember that they are not
inflation adjusted, so it would be unrealistic to expect them to have the same
purchasing power in the future as they would today.

We also encourage you to use this mailing as a reason to contact your investment
professional, or to select one if you are not working with somebody. He or she
can help you focus on establishing and maintaining a sound plan to achieve a
comfortable retirement. Together, you should make sure to maximize your
participation in tax-advantaged programs like IRAs and 401(k)s.

The stakes are too high to leave your retirement lifestyle to chance. Congress'
awareness-raising effort is commendable. The next step is yours. Mark the
beginning of the New Millennium by taking it.

Sincerely,


/s/ Maureen R. Ford

           BY MIREN ETCHEVERRY AND JOHN L.F. WILLS, PORTFOLIO MANAGERS

                                  John Hancock
                               International Fund

                         Japan and emerging markets top
                       international performance this year

Recently, shareholders voted to approve a new subadvisory investment management
contract with Indocam International Investment Services, effective January 1,
2000.

The last 12 months were productive for overseas investors, as world financial
markets settled down after last year's global economic turmoil. Japan and the
emerging markets of Asia provided the largest returns, as many of the Southeast
Asian countries that sparked the problems in 1997 showed particularly strong
signs of recovery. Lower interest rates and a pickup in exports and growth
produced especially strong results in South Korea, Thailand and Malaysia. Japan,
whose signs of economic recovery remain more tentative, benefited from a bank
re-capitalization plan and several major corporate restructurings. These served
as signals for foreign investors to re-enter the Japanese market and also caused
the yen to strengthen versus the dollar.

      In Europe, a slowdown in economic growth for most of the period, the
decline of the new euro common currency and rising interest rates in the second
half of the fiscal year caused those markets to cool, yet the region still
managed to return 10% overall. Although still in recession in 1999, Latin
American markets also produced positive results due to the rise in commodity
prices, which helped these commodity-dependent markets. Several individual
country concerns held the Latin markets back as the year progressed.

      Even though the second half of the fiscal period became more turbulent as
concerns about rising U.S. interest rates filtered through foreign markets, the
world as a whole kept pace with the United States. Our benchmark Morgan Stanley
Capital International (MSCI) All Country World Free Ex-U.S. Index returned
25.26% for the year ended October 31, 1999, compared to the 25.67% return of the
Standard & Poor's 500 Index.

Fund performance

John Hancock International Fund participated in the strength of overseas markets
to much the same degree as our peers. For the year ended October 31, 1999, the
Fund's Class A, Class B and Class C shares posted total returns of 24.29%,
23.39% and 23.63%, respectively, at net asset value. That compared to the 25.53%

mind that your net asset value return will be different from the Fund's

on pages six and seven.

Shifting assets to Asia, emerging markets

Starting in the spring, as we grew more confident in the improved prospects for
recoveries in Japan and the emerging markets, we repositioned the portfolio to
up our stakes in those regions. In so doing, the Fund moved to a more average
weight in continential Europe and the United Kingdom -- 54%, down from 84% a
year ago -- and became more regionally balanced. After re-entering Hong Kong and
Brazil in the first half of the year, we re-established positions in South
Korea, Taiwan, Indonesia, China and Thailand in the second half. This, along
with an increase in Japan, caused our Asian exposure to rise from 11% a year ago
to 39% at the end of October. We also re-established a small foothold in Mexico
in the second half of the year.

Japan grows

During the course of the year, Japan grew from 8% to 27% of the Fund's net
assets through a combination of additional names and strong performance, so that
we ended the year slightly overweighted versus our benchmark and peers. Japan
was also the biggest contributor to the Fund's performance. The best performers
there included Sony, which announced a major corporate restructuring, and Sakura
Bank and Nomura Securities, both of which rebounded after the proposed merger of
three large banks further bolstered confidence in the financial sector. Fujitsu,
one of the largest manufacturers of computer and electronics components, is also
thriving on the telecom equipment boom.

   The two fundamental themes driving the Japanese markets are the prospects for
economic recovery and the potential for corporate restructuring. Our Japanese
portfolio is composed of blue-chip companies benefiting from those themes, as
well as from the government's bank re-capitalization plan and the re-emergence
of the Japanese consumer.

Europe: cut but still important

We got to our reduced focus in Europe by cutting our overweighting in France and
lowering our stakes in the U.K., Switzerland and Belgium. Nonetheless, we plan
to keep an important position in Europe because of the opportunities that still
abound around corporate restructurings and industry consolidation. What's more,
despite rising interest rates late in the

period, Europe's growth rate began to rebound without signs of inflation, due to
a pickup in demand fueled by Asia's recovery and a weak euro that helped
exporters.

      Europe still produced some of our biggest winners, such as leading
cellular-phone manufacturer Nokia and and Royal Philips Electronics. There were
also disappointments, however, including Allied Irish Banks, which was unduly
hit by concerns over its recent merger with a Singapore bank, and
DaimlerChrysler, which the market punished for not moving fast enough to realize
the synergies of its famous merger.

Cautious optimism ahead

We remain encouraged about the long-term prospects for international equities,
while being alert to the growing potential for uncertainties in the nearer term.
These include year 2000 computer concerns ("Y2K") and the potential for rising
U.S. interest rates and persistent robust growth, which could slow down
worldwide growth.

      The fundamentals of Europe and Japan are strong. In Europe, the impending
pickup in economic growth should help corporate earnings growth, while major
alliances continue to accelerate. While Japan is still sending contrasting
signals, consumer spending is growing at a sustained pace, despite a fall in
income and the ongoing deterioration of the labor market. Japan is also
benefiting from a rebound in external demand coming from its strengthening Asian
neighbors.

      Barring a series of U.S. interest rates or major Y2K dislocations, which
we do not anticipate, we believe the outlook for emerging markets is also
positive. Latin America is expected to recover from its 1999 recession and grow
3% next year. Emerging Asian markets are expected to maintain a robust growth in
excess of 5%, even assuming modest growth in Japan, the region's economic
engine.

equities..."

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

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

Note to Performance

(1)   Effective January 3, 1994, the Adviser has voluntarily undertaken to
      temporarily 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 returns for the one-year period, five-year period and since
      inception would have been 19.47%, 1.64% and 0.95%, respectively, for Class
      A shares and 20.09%, 1.59% and 0.99%, respectively, for Class B shares.
      The average annual total returns for the one-year period and since
      inception would have been 24.09% and 3.27%, respectively, for Class C
      shares.

investment in the Morgan Stanley Capital International (MSCI) All Country World
Free Ex-U.S. Index, which measures the performance of a broad range of developed
and emerging stock markets around the world. The index represents "free"
securities that are traded freely on equity exchanges around the world. It is
not possible to invest in an index. Past performance is not indicative of future
results.

                     John Hancock Funds - International Fund

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 four series: John Hancock International Fund (the
"Fund"), John Hancock Global Fund, John Hancock Large Cap Growth Fund and John
Hancock Mid Cap Growth 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
three series of the Trust are reported in separate financial statements. The
investment objective of the Fund is long-term growth of capital through
investment primarily in stocks of foreign companies.

      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 to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees if any, are calculated daily

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

                     John Hancock Funds - International Fund

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 Funds 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 year ended October 31, 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 October 31, 1999, the Fund
loaned securities having a market value of $1,105,904 collateralized by cash in
the amount of $1,134,144, which 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 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 October 31, 1999, open forward foreign currency exchange contracts were
as follows:

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 the transfer agent fee and the 12b-1 fee), to 0.90% of
the Fund's average daily net assets. Accordingly, the reduction in the Adviser's
fee and other Fund expenses amounted to $294,784 for the year ended October 31,
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 year ended October
31, 1999, net sales charges received with regard to sales of Class A shares
amounted to $28,023. Out of this amount, $3,752 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $17,304
was paid as sales commissions to unrelated broker-dealers and $6,967 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 year ended October 31, 1999,
contingent deferred sales charges paid to JH Funds amounted to $70,804.

      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 year ended October 31, 1999, contingent deferred sales charges paid to JH
Funds amounted to $563.

      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. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, 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,
accounting and legal services for the Fund. The compensation for the year 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. Maureen R. Ford,
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 through
December 31, 1999. 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.

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 year
ended October 31, 1999, aggregated $17,561,172 and $20,438,012, respectively.
There were no purchases or sales of obligations of the U.S. government and its
agencies during the year ended October 31, 1999.

      The cost of investments owned at October 31, 1999 (including short-term
investments) for federal income tax purposes was $15,364,269. Gross unrealized
appreciation and depreciation of investments aggregated $3,077,002 and $447,304
respectively, resulting in net unrealized appreciation of $2,629,698.

NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended October 31, 1999, the Fund has reclassified amounts to
reflect a decrease in net realized gain on investments and foreign currency
transactions of $549,098, a decrease in accumulated net investment loss of
$42,060 and an increase in capital paid-in of $507,038. This represents the
amount necessary to report these balances on a tax basis, excluding certain
temporary difference, as of October 31, 1999. Additional adjustments may be
needed in subsequent reporting periods. These reclassifications, which have no
impact on the net asset value of the Fund, are primarily attributable to the net
operating loss, net realized loss on foreign currency transactions and Passive
Foreign Investment Companies in the computation of distributable income and
capital gains under federal tax rules versus generally accepted accounting
principles and the Fund's use of the tax accounting practice known as
equalization. The calculation of net investment income per share in the
financial highlights excludes these adjustments.

REPORT OF INDEPENDENT AUDITORS
To the Shareholders of John Hancock International Fund and
the Trustees of John Hancock Investment Trust III

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of John Hancock International Fund
(the "Fund") (a series of John Hancock Investment Trust III) at October 31,
1999, and the results of its operations, the changes in its net assets and the
financial highlights for the periods indicated, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and the significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities owned at October 31, 1999 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
