                               CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:


Educating shareholders has always been one of the most important
responsibilities of a mutual fund company. But that challenge has taken on new
significance in the past several years. Looking at the most recent statistics,
you can see why. According to the Investment Company Institute, the mutual fund
industry now manages more than $2.3 trillion for investors. More than half of
that money has come into mutual funds in just the last four years. Today, there
are more than 95 million mutual fund shareholder accounts. That's up from 12
million in 1980. These are people, like you, who are investing in mutual funds
to save for a home, to send their children to college or to build a nest egg for
a comfortable retirement. This explosive growth, coupled with the growing
complexity of the financial landscape, has made all of us in the mutual fund
industry work harder to inform our shareholders.

   At John Hancock Funds, we strive to educate you about all aspects of your
fund: the performance, the strategies and the holdings. We want you to fully
understand what you own. We want you to have realistic expectations of the
potential rewards as well as the potential risks of your investment. These
shareholder reports -- which we send you twice a year -- are the best way to
give you the most in-depth and up-to-date information.

   In the message that follows, the portfolio manager gives a candid commentary
on the market environment; the factors that affected performance; the fund's
current investment strategies; and the outlook for the months ahead. The ensuing
financial statements provide a comprehensive look at the fund's statistics and
holdings. We've included explanations of what each financial statement shows and
how it is used.

   We hope you find these shareholder reports a useful tool in evaluating your
investments. Of course, if you have any questions or need more information, feel
free to call one of our customer service representatives on our toll-free line
at 1-800-225-5291, from 8:00 a.m. to 8:00 p.m. eastern time, Monday through
Friday.

Sincerely,

/s/ Edward J. Boudreau, Jr.

                      MUNICIPAL BONDS TURN CORNER IN 1995;
                       SECOND HALF SHOULD REMAIN POSITIVE

Thomas C. Goggins is a member of the portfolio management team of John Hancock
Tax-Free Bond Fund. Mr. Goggins heads up Hancock's team of municipal bond
portfolio managers and analysts. He is also portfolio manager of John Hancock
Tax-Exempt Income Fund.

Municipal bonds reversed course during the first half of 1995 and enjoyed one of
their strongest periods of the decade. After being battered by higher interest
rates and weak demand during most of 1994, municipals turned the corner in
January. At that time, the economy appeared to be slowing and inflation was low.
As a result, investors became less worried that the Federal Reserve Board would
continue its 1994 policy of raising short-term interest rates. In addition,
demand for municipal bonds started to strengthen, bucking up against limited
supply. All in all, municipals were the top performing fixed-income category
during the first quarter.

   In the second quarter, however, municipals hit a few bumps. One was talk of a
flat tax in April, which, if enacted, would eliminate the tax-free advantage
municipals now enjoy. In our view, however, it's unlikely that a flat tax will
ever be enacted and the market appears to have overreacted. Later in the
quarter, voters in Orange County, California failed to pass a tax bill intended
to help pay for the county's 1994 investment losses. These events cast a slight

pall over the municipal market, but not enough to eliminate its earlier gains.

A LOOK AT PERFORMANCE

For the six months ended June 30, 1995, John Hancock Tax-Free Bond Fund's Class
A and Class B shares posted returns of 10.16% and 9.85%, respectively, at net
asset value. Those returns outpaced the average general municipal bond fund's
return of 9.01% for the same period, according to Lipper Analytical Services.1

   The primary reason for the Fund's outperformance was its relatively long
duration, particularly in the first quarter of the year. Duration measures a
fund's price volatility for a given change in interest rates. The longer a
fund's duration, the more sensitive its share price is to rising or falling
interest rates. When interest rates fell, the Fund's performance benefited.

   Toward the end of the second quarter, however, the difference in yield
between long- and short-term bonds narrowed -- which is known as a flattening
yield curve. As a result, there was little incentive for investors to take on
the added interest-rate risk of longer-term bonds. So we started to lock in
profits by selling longer-term bonds and buying shorter-term bonds. The net
effect was a shorter duration for the Fund. Going forward, we will actively
manage duration, shortening and lengthening as market conditions warrant.

FOCUS ON SECTORS

At 27% of the Fund's assets, health-care bonds made up our largest sector
concentration. While the health-care industry has recently been faced with a
number of competitive and cost pressures, we continue to maintain holdings in
many of its bonds, mainly because of their attractive yields. Using careful
analysis and research, we're looking for hospitals with strong participation
from health maintenance organizations and low cost structures. We think that
these factors are key to picking the hospitals that will be winners in a more
competitive environment.

   More recently, we've found opportunities in electric utility bonds. Many
investors shunned the bonds last year due to worries about less regulation and
increased competition. We purchased many of these bonds after they had fallen to
quite attractive levels. In our view, true competition is lot farther off than
the municipal market has taken into account. Central Maine Power and North
Carolina Eastern Municipal Power Agency were two additions to this sector.

OUTLOOK

Continued debate about various tax reform proposals could add volatility to the
municipal market in the months to come. But as we mentioned earlier, we don't
believe that the flat tax proposal -- the one which would most negatively impact
municipal bonds -- is likely to be enacted.

   Looking forward, we remain optimistic about the municipal bond market. One
reason is the long-term trend toward a diminished supply of municipal bonds.
That's because municipalities aren't planning as many capital projects as voters
become more reluctant to pay for them with higher taxes. What's more, many of
the municipalities that could refinance their borrowings of the high-flying `80s
at lower rates have already done so. Let's take a look at the numbers. In 1993,
municipal bond supply stood at $292 billion. By 1994, supply had fallen off by
about half the previous year's level and it's expected to be about $120 billion
by the end of 1995. Decreasing supply and constant demand should be a positive
for the municipal bond market. In addition, municipal bonds continue to offer a
relatively attractive after-tax yield, which may attract new investors.

   In our view, the U.S. economy is growing slowly but steadily. It's not in any
real danger of overheating or dipping into a recession. Therefore, we believe
that inflation will stay low and interest rates will stabilize. Against that
backdrop, most of municipal bond performance will probably come from income
rather than big price gains. So we'll continue to look for opportunities to
improve and enhance the Fund's yield.

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

The tables on the right show the cumulative total returns and the average annual
total returns for John Hancock Tax-Free Bond Fund. Total return is a performance
measure that equals the sum of all income and capital gains dividends, assuming
reinvestment of these distributions, and the change in the price of the fund's
shares, expressed as a percentage of the fund's share. Performance figures
include the maximum applicable sales charge of 4.5% for Class A shares. The
effect of the maximum contingent deferred sales charge for Class B shares
(maximum 5% and declining to 0% over six years) is included in Class B
performance. Remember that all figures represent past performance and are no
guarantee of how the Fund will perform in the future. Also, 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.

Note: Participant-directed defined-contribution plans with at least 100 eligible
employees at inception of the Fund account may purchase Class A shares without
an initial sales charge as of March 15, 1995. If those shares are redeemed,
however, during the year following the calendar year end during which they were
purchased, a contingent deferred sales charge will be assessed.

                     John Hancock Funds - Tax-Free Bond Fund

(UNAUDITED)
NOTE A --
ACCOUNTING POLICIES

John Hancock Tax-Free Bond Fund (the "Fund") is a diversified open-end
investment management company registered under the Investment Company Act of
1940.

   The Trustees have authorized the issuance of two classes of the Fund,
designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund and have equal rights
to voting, redemption, 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/service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such distribution plan. Class A
shares are subject to an initial sales charge of up to 4.50% and a 12b-1
distribution plan. Prior to May 15, 1995, the maximum sales charge was 4.75%.
Class B shares are subject to a contingent deferred sales charge and a separate
12b-1 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,
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.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investments, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has approximately $7,350,000
of capital loss carryforward available, to the extent provided by regulations,
to offset future net realized capital gains. If such carryforward is used by the
Fund, no capital gain distribution will be made. The carryforward expires
December 31, 2002.

DIVIDENDS, DISTRIBUTIONS, AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

   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 as explained previously.

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 appropriate net assets of the respective classes.
Distribution/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 of each class.

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. At the time the Fund
enters into a financial futures contract, it is


                                       17
<PAGE>   18
                         NOTES TO FINANCIAL STATEMENTS

                     John Hancock Funds - Tax-Free Bond Fund


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. 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 contract 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 transactions.

   At June 30, 1995, open positions in financial futures contracts were as

</TABLE>


   At June 30, 1995, the Fund has deposited in a segregated account $360,000 to
cover margin requirements on open financial futures contracts.

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the amount paid
in excess of par value on securities purchased from either the date of purchase
or date of issue to date of sale, maturity or to next call date, if applicable.
The Fund accretes original issue discount from par value on securities purchased
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code. The Fund records market
discount on bonds purchased after April 30, 1993 at the time of disposition.

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 at an annual
rate of 0.55% of the Fund's average daily net asset value.

   In the event normal operating expenses of the Fund, exclusive of certain
expenses prescribed by state law, are in excess of the most restrictive state
limit where the Fund is registered to sell shares, the fee payable to the
Adviser will be reduced to the extent of such excess, and the Adviser will make
additional arrangements necessary to eliminate any remaining excess expenses.
The current limits are 2.5% of the first $30,000,000 of the Fund's average daily
net asset value, 2.0% of the next $70,000,000, and 1.5% of the remaining average
daily net asset value.

   The Adviser has agreed to limit Fund expenses, including the management fee
(but not including the 12b-1 fee), to 0.70% of the Fund's average daily net
assets. Accordingly, the reduction in the Adviser's fee amounted to $109,422 for
the period ended June 30, 1995. 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 June 30,
1995, JH Funds received net sales charges on sales of Class A shares of the Fund
in the amount of $76,264. Out of this amount, $8,188 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $65,719
was paid as sales commissions and service fees to unrelated broker-dealers and
$2,357 was paid as sales commissions and service fees to sales personnel of John
Hancock Distributors, Inc. ("Distributors"), Tucker Anthony, Incorporated
("Tucker Anthony") and Sutro & Co., Inc. ("Sutro"). Distributors is a
wholly-owned

                     John Hancock Funds - Tax-Free Bond Fund


subsidiary of John Hancock Funds. The Adviser's indirect parent, John Hancock
Mutual Life Insurance Company, is the indirect sole shareholder of Distributors
and John Hancock Freedom Securities Corporation and its subsidiaries, which
include Tucker Anthony and Sutro, all of which are broker-dealers.

   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 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 June 30, 1995,
contingent deferred sales charges received by Broker Services amounted to
$131,568.

   In addition, to compensate 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 and Class B shares 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
0.15% of Class A average daily net assets and 0.90% of Class B average daily net
assets to reimburse JH Funds for its distribution and service costs. Up to a
maximum of 0.15% of these 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 Board of Trustees approved a shareholder servicing agreement between the
Fund and John Hancock Investor Services Corporation ("Investor Services"), a
wholly-owned subsidiary of The Berkeley Financial Group, for the period between
December 22, 1994 and May 12, 1995, inclusive under which Investor Services
processed telephone transactions on behalf of the Fund. As of May 15, 1995, the
Fund entered into a full service transfer agent agreement with Investor
Services. Prior to this date The Shareholder Services Group was the transfer
agent. The Fund pays Investor Services a fee based on the number of shareholder
accounts and certain out-of-pocket expenses.

   Messrs. Edward J. Boudreau, Jr. and 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. Effective with
the fees paid for 1995, the unaffiliated Trustees may elect to defer for tax
