                               CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

The Taxpayer Relief Act of 1997 recently signed into law by President
Clinton includes new twists and important changes to Individual Retirement
Account (IRA) laws. The provisions will, among other things, allow more people
to qualify for annual tax-deductible IRA contributions and to save tax-free for
college. They also allow IRA investors to withdraw money penalty-free from all
IRAs to buy a first home or pay for college expenses.

[A 1 x 1 1/4" photo of Edward J. Boudreau Jr., Chairman and Chief Executive
Officer, flush right, next to second paragraph.]

      For existing deductible IRAs, the law doubles income limits over the next
eight to 10 years for those eligible to deduct an annual IRA contribution of up
to $2,000. For individuals, the annual income cap will increase incrementally
from the current $25,000 to $50,000 by 2005. For couples, the limit would
increase from $40,000 today to $80,000 in 2007. The new law allows non-working
spouses to make IRA contributions even if their spouse is covered by a pension
plan at work, provided the couple's joint income is less than $150,000.

      The law also creates two new IRA investment vehicles. One, called the
"Roth IRA" after its principal congressional sponsor, allows for non-deductible
annual contributions up to a $2,000 maximum. But income accumulates tax-free and
if the account has been open for five years, distributions are tax-free if they
are used after age 591/2 or upon death, disability or a first-time home
purchase. Withdrawals for higher-education expenses would not be subject to a
10% penalty. Eligible investors must earn less than $95,000 per year
individually or $150,000 per couple.

      A second new IRA plan is called the "Education IRA," which allows non-
deductible contributions of up to $500 per year, per child under age 18.
Earnings in the account accumulate tax-free, and withdrawals are also not taxed
when applied toward undergraduate or graduate-level expenses. Eligible investors
are subject to the same income restrictions as the Roth IRA.

      The law has also made some important changes in capital gains tax rates
and estate tax laws. But the devil is in the details, and so we recommend
exploring how you can benefit from the changes with your investment professional
and tax advisor. The Taxpayer Relief Act of 1997 gives investors new options
toward savings. It's a move we applaud.

Sincerely,


/s/ Edward J. Boudreau, Jr.

                                  John Hancock
                             Massachusetts Tax-Free
                                   Income Fund

                    Municipal bonds turn in solid performance

The bond market rode waves of volatility over the last 12 months. Fear about a
rebirth of inflation -- dreaded by bond holders for its erosive effects on fixed
income investments -- alternated during the year with elation over economic data
that showed inflation at barely noticeable levels. When the economy picked up
steam early this year and investors' concerns grew, the Federal Reserve Board
raised interest rates a quarter percentage point as an insurance policy against
inflation. Interest rates rose and bond prices fell both leading up to, and in
the wake of, the Fed action. In fact, the conflicting opinions of analysts who
held to the traditional theory that a surging economy inevitably leads to higher
inflation, and of those who embrace the "new era" belief that the economy can
grow at a faster pace today without inflation, added to the market's wavering.
But by the end of April, bonds staged a rally that lasted through July as it
became clear that the economy had slowed from its blistering first quarter 1997
pace and the Fed made no further attempts to rein it in.

      Even with the increased volatility, bonds moved ahead overall during the
year. Municipal bond performance was further enhanced by the continuing positive
trends of reduced supply and strong demand. With this backdrop, John Hancock
Massachusetts Tax-Free Income Fund

turned in a strong performance. For the 12 months ended August 31, 1997, the
Fund's Class A shares posted a total return of 9.85% at net asset value. By
comparison, the average Massachusetts municipal bond fund returned an average
8.55%, according to Lipper Analytical Services, Inc. 1 Please see pages six and
seven for longer-term performance. The Fund's Class B shares, which began on
October 3, 1996, returned 7.08% at net asset value from inception through August
31, 1997.

Strategy and performance review

Throughout the year, our careful management of portfolio duration helped the
Fund's performance. Duration is a measure of how much a bond's price changes in
response to changing interest rates. The shorter the duration, the less a bond's
price moves with rate changes. At the beginning of the period last September,
the Fund's duration was longer than average, helping us in last fall's market
rally. As the economy heated up earlier this year, we became more conservative
and made duration shorter than average, which helped in the market's spring
retreat. But in May when inflation fears ebbed, we reversed course and brought
duration back to neutral relative to our peers. We're keeping it there for now,
given the rally that's already occurred and the market's skittishness about the
economy's strength.

      Performance boosts came during the year from our bonds with attractive
yields and good call protection (the length of time during which a security
cannot be redeemed prior to its maturity). In particular, our non-callable
bonds, those that cannot be redeemed before their scheduled maturity, did well.
Our focus on bonds with good structure has been a priority for the Fund over the
past several years. As we have discussed in previous reports, having strong call
protection helps the Fund maintain greater income stability by preventing a
greater portion of the Fund's holdings from being called away by municipalities
looking to refinance their debt at lower interest rates. Early calls can reduce
returns because bondholders are forced to reinvest the proceeds at lower yields.

      By far the strongest contributors to the Fund's performance over the last
12 months were our uninsured, lower-rated bonds. Now that 65% of municipal bonds
coming to the market have bond insurance (a policy that ensures the timely
payment of principal and interest), the supply of lower-rated, uninsured bonds
has dwindled. At the same time, demand for these higher-yielding bonds has
increased, causing their prices to rise

significantly in the last 12 months. Our in-depth credit analysis has led us to
some uninsured bonds with solid underlying fundamentals, strong liquidity and
attractive yields.

      Among our best-performing BBB-rated bonds were those issued by the
Massachusetts Industrial Financial Authority (MIFA) for American Hingham Water
Company, a private company providing essential water services to the Hingham
area south of Boston. Our uninsured holdings in the hospital sector have also
continued to perform very well, due to both the strength of the underlying
credits and ongoing hospital mergers. For example, New England Deaconess and
Beth Israel hospitals are moving ahead with their consolidation plans, gaining
all-important cost efficiencies in the process.

      Non-rated bonds have also been strong performers. These are bonds that
have not been rated by any of the credit rating agencies for a variety of
reasons, ranging from the small size or structure of the offering, to the
industry involved, to a perceived higher degree of risk. But with careful
analysis and selection, non-rated bonds offer good opportunities. A perfect
example were our non-rated bonds issued by MIFA for a senior independent living
complex in East Longmeadow. These bonds are attractive because of the strong
demographics in the East Longmeadow area and because of the complex's attractive
design and well-established, respected management team.

A look ahead

We're encouraged by the prospects for the Massachusetts municipal bond market.
The state's economy keeps building at a solid, steady rate. Real estate has
rebounded sharply, unemployment is lower than the national average and state
revenues remain above expectations. In this positive environment, the state has
begun to address the backlog of infrastructure needs left over from the lean
years. That's good news not only for the state, but also for municipal bond
funds that have been constrained by the paucity of new bond issuance in
Massachusetts for several years now. We'll watch to see what opportunities
emerge, especially as the state makes clearer how it intends to pay for its
largest project to date --rebuilding the Central Artery in downtown Boston.

"...we'll
continue to
focus on
increasing
the Fund's
competitive
yield..."

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Massachusetts Tax-Free Income Fund. Total
return is a performance measure that equals the sum of all income and capital
gains distributions, assuming reinvestment of these distributions, and the
change in the price of the Fund's shares, expressed as a percentage of the
Fund's net asset value per 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. Performance is affected
by a 12b-1 plan. 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.

      Please note that a portion of the Fund's income may be subject to taxes,
and some investors may be subject to the Alternative Minimum Tax. Also note that
capital gains are taxable when distributed to shareholders.

      portion of the custodian fees have been reduced by balance credits during
      the period. Without the reductions of expenses, the average annual total
      returns for the one-year, five-year and since inception periods for Class
      A shares would have been 3.44%, 5.30% and 6.91%, respectively. The average
      annual total return since inception for Class B shares would have been
      (0.24%).

                         NOTES TO FINANCIAL STATEMENTS

            John Hancock Funds -- Massachusetts Tax-Free Income Fund

NOTE A --
ACCOUNTING POLICIES

John Hancock Tax-Exempt Series Fund (the "Trust") is a diversified open-end
management investment company registered under the Investment Company Act of
1940. The Trust consists of two series: John Hancock Massachusetts Tax-Free
Income Fund (the "Fund") and John Hancock New York Tax-Free Income Fund. The
other series of the Trust is reported in separate financial statements. The
investment objective of the Fund is to provide as high a level of current income
exempt from both federal income taxes and Massachusetts personal income taxes as
is consistent with preservation of capital.

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A and Class B 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. On October 3, 1996, Class B shares of beneficial interest were sold to
commence class activity.

      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
investment, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $524,746 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. To the extent such carryforwards are used by the
Fund, no capital gains distribution will be made. The carryforwards expire as
follows: August 31, 2003 -- $387,469, August 31, 2004 -- $137,277. Additionally,
net capital losses of $5,384 attributable to security transactions incurred
after October 31, 1996 are treated as arising on the first day (September 1,
1997) of the Fund's next taxable year.

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.

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 Inter-

nal Revenue Code. The Fund records market discount on bonds purchased after
April 30, 1993 at time of disposition.

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 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 that 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 relative
sizes 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. The Fund had no borrowing
activity for the period ended August 31, 1997.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts 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 will be 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 on 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," will be 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
fluctuation imposed by an exchange.

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

      At August 31, 1997, open positions in financial futures contracts were as
follows:

                                                     UNREALIZED
EXPIRATION     OPEN CONTRACTS             POSITION   APPRECIATION
- ----------     --------------             --------   ------------
DEC 97         20 U.S. TREASURY BONDS     LONG          $1,250
                                                        ======

      At August 31, 1997, the Fund had deposited $36,000 in a segregated account
to cover margin requirements on open financial futures contracts.

OPTIONS Listed options will be valued at the last quoted sales price on the
exchange on which they are primarily traded. Purchased put or call
over-the-counter options will be valued at the average of the "bid" prices
obtained from two independent brokers. Written put or call over-the-counter
options will be valued at the average of the "asked" prices obtained from two
independent brokers. Upon the writing of a call or put option, an amount equal
to the premium received by the Fund will be included in the Statement of Assets
and Liabilities as an asset and corresponding liability. The amount of the
liability will be subsequently marked to market to reflect the current market
value of the written option.

      The Fund may use option contracts to manage its exposure to the price
volatility of financial instruments. Writing puts and buying calls will tend to
increase the Fund's exposure to the underlying instrument


                                       17

================================================================================

                         NOTES TO FINANCIAL STATEMENTS

            John Hancock Funds -- Massachusetts Tax-Free Income Fund

and buying puts and writing calls will tend to decrease the Fund's exposure to
the underlying instrument, or hedge other Fund investments.

      The maximum exposure to loss for any purchased options will be limited to
the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

      Risks may also arise if counterparties do not perform under the contract's
terms ("credit risk"), or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit and liquidity risks in over-the-counter option contracts, the Fund will
continuously monitor the creditworthiness of all its counterparties.

      At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's period-end
Statement of Assets and Liabilities.

      There were no written option transactions for the period ended August 31,
1997.

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) 0.500% of the first $250,000,000 of the
Fund's average daily net asset value, (b) 0.450% of the next $250,000,000, (c)
0.425% of the next $500,000,000, (d) 0.400% of the next $250,000,000 and (e)
0.300% of the Fund's average daily net asset value in excess of $1,250,000,000.

      The Adviser has voluntarily agreed to limit the Fund's expenses further to
the extent required to prevent expenses from exceeding 0.70% and 1.40% of the
average net assets attributable to Class A and Class B, respectively.
Accordingly, for the period ended August 31, 1997, the reduction in the
Adviser's fee collectively with any additional amounts not borne by the Fund by
virtue of the expense limit amounted to $217,030. This limitation may be
discontinued at any time.

      The Fund has an agreement with its custodian bank under which $5,901 of
custodian fees have been reduced by balance credits applied during the period
ended August 31, 1997. If the Fund had not entered into this agreement, the
assets not invested, on which these balance credits were earned, could have
produced taxable income.

      The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the period ended August
31, 1997, net sales charges received with regard to sales of Class A shares
amounted to $153,486. Out of this amount, $15,682 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $76,086
was paid as sales commissions to unrelated broker-dealers and $61,718 was paid
as sales commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

      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 for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended August 31, 1997
the contingent deferred sales charges received by JH Funds amounted to zero.

      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 and Class B 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 average daily net assets,
to reimburse JH Funds for its distribution and service costs. Up to a maximum of
0.25% of such payments

                         NOTES TO FINANCIAL STATEMENTS

            John Hancock Funds -- Massachusetts Tax-Free Income Fund

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 Funds. 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., Ms. Anne C. Hodsdon and Mr. Richard S.
Scipione are trustees 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 another 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 August 31, 1997, the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $409.

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 August 31, 1997, aggregated $6,626,863 and $7,249,824, respectively. There
were no purchases or sales of obligations of the U.S. government and its
agencies during the period ended August 31, 1997.

      The cost of investments owned at August 31, 1997 for federal income tax
purposes was $51,967,425. Gross unrealized appreciation and depreciation of
investments aggregated $3,522,620 and none respectively, resulting in net
unrealized appreciation of $3,522,620.

NOTE D --
Reclassification of accounts

During the year ended August 31, 1997, the Fund has reclassified amounts to
reflect a decrease in accumulated net realized loss on investments of $93, a
decrease in undistributed net investment income of $74 and a decrease in capital
paid-in of $19. This represents the amount necessary to report these balances on
a tax basis, excluding certain temporary differences, as of August 31, 1997.
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 certain differences in the computation of
distributable income and capital gains under federal tax rules versus generally
accepted accounting principles. The calculation of net investment income per
share in the financial highlights excludes these adjustments.

                         NOTES TO FINANCIAL STATEMENTS

            John Hancock Funds -- Massachusetts Tax-Free Income Fund

REPORT OF INDEPENDENT AUDITORS
To the Shareholders and Board of  Trustees of
John Hancock Massachusetts Tax-Free Income Fund

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments (except for credit ratings and yields at market),
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 the Massachusetts Tax-Free Income Fund (the "Fund") at August 31,
1997, 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 significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at August 31, 1997 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

                               CHAIRMAN'S MESSAGE
DEAR FELLOW SHAREHOLDERS:

The Taxpayer Relief Act of 1997 recently signed into law by President Clinton
includes new twists and important changes to Individual Retirement Account (IRA)
laws. The provisions will, among other things, allow more people to qualify for
annual tax-deductible IRA contributions and to save tax-free for college. They
also allow IRA investors to withdraw money penalty-free from all IRAs to buy a
first home or pay for college expenses.

[A 1 1/4" photo of Edward J. Boudreau Jr., Chairman and Chief Executive Officer,
flush right, next to second paragraph]

      For existing deductible IRAs, the law doubles income limits over the next
eight to 10 years for those eligible to deduct an annual IRA contribution of up
to $2,000. For individuals, the annual income cap will increase incrementally
from the current $25,000 to $50,000 by 2005. For couples, the limit would
increase from $40,000 today to $80,000 in 2007. The new law allows non-working
spouses to make IRA contributions even if their spouse is covered by a pension
plan at work, provided the couple's joint income is less than $150,000.

      The law also creates two new IRA investment vehicles. One, called the
"Roth IRA" after its principal congressional sponsor, allows for non-deductible
annual contributions up to a $2,000 maximum. But income accumulates tax-free and
if the account has been open for five years, distributions are tax-free if they
are used after age 591/2 or upon death, disability or a first-time home
purchase. Withdrawals for higher-education expenses would not be subject to a
10% penalty. Eligible investors must earn less than $95,000 per year
individually or $150,000 per couple.

      A second new IRA plan is called the "Education IRA," which allows
non-deductible contributions of up to $500 per year, per child under age 18.
Earnings in the account accumulate tax-free, and withdrawals are also not taxed
when applied toward undergraduate or graduate-level expenses. Eligible investors
are subject to the same income restrictions as the Roth IRA.

      The law has also made some important changes in capital gains tax rates
and estate tax laws. But the devil is in the details, and so we recommend
exploring how you can benefit from the changes with your investment professional
and tax advisor. The Taxpayer Relief Act of 1997 gives investors new options
toward savings. It's a move we applaud.

Sincerely,


/s/ Edward J. Boudreau, Jr.

EDWARD J. BOUDREAU, JR., CHAIRMAN AND CHIEF EXECUTIVE OFFICER

                       Low inflation, strong local economy
                          help buoy New York municipals

Troubled by contradictory news on the job, retail spending and consumer price
fronts, bond prices see-sawed during much of the first half of the Fund's fiscal
year beginning September 1, 1996. While many cheer strong economic reports, bond
investors fear them because they worry that such strength may be an indication
that inflation is on the rise. Inflation, of course, is the bugaboo of bond
investing because it eats away at the value of bonds' fixed-income payments. In
March, the Federal Reserve Board raised short-term interest rates one-quarter of
a percentage point, in a pre-emptive effort to stave off any future inflation.
That action rattled bond investors who pushed bond prices lower and yields
higher in February and March.

      It really wasn't until April when bond prices showed definitive signs of
sustained improvement. At that point, there was plenty for bond investors to
cheer about. Even though the U.S. unemployment rate hit a 23-year low, there
were no real signs that wages -- often a large contributor to higher inflation
- -- were on the rise. Adding further fuel to the bond market's optimism was
Federal Reserve Board Chairman Alan Greenspan's July testimony to Congress.
While he admitted puzzlement that despite the economy's strong growth and low
unemployment no inflationary pressures were brewing, he strongly hinted that no
further interest-rate hikes were on the immediate horizon.

      For the year ended August 31, 1997, John

Hancock New York Tax-Free Income Fund's Class A shares posted a total return of
9.48% at net asset value, which was ahead of the average New York municipal bond
fund's 8.93% return for the same period, according to Lipper Analytical
Services, Inc.(1) The Fund's Class B shares, which began on October 3, 1996, had
a total return of 6.82% at net asset value from inception through August 31,
1997. Please see pages six and seven for longer-term performance.

Winners: New York City, high-coupon bonds

Throughout the past year, our holdings in bonds issued by New York City were
some of our best performers, buoyed by three fundamental developments. First was
the perception that the credit quality of these bonds had improved. The rising
stock market has been an overwhelming positive for the fortunes of many Wall
Street firms, which are dominant players in the city's economy. Thanks to rising
personal income and corporate tax receipts and falling expenditures, New York
City's fiscal picture has enjoyed substantial improvement over the past couple
of years. Second, there was a healthy demand for New York City bonds. In an
environment where nearly half of all bonds issued across the state were insured,
uninsured New York City bonds were sought after by investors searching for
yields in excess of those offered by insured bonds. Third, the city reached the
statutory cap of the amount of general obligation (GO) debt it can issue. Given
that, and the formation of the Transitional Finance Authority -- which will
issue additional debt for the city -- the expectation is that there isn't going
to be a lot of New York City GO debt issued over the next couple of years. The
anticipated lack of future supply also helped New York City bonds rally. Bonds
issued by the New York City Industrial Development Agency for Visy Paper were
boosted because there was a low supply of high-yielding bonds and because of the
successful startup of this plant, which recycles the city's waste paper into
corrugated cardboard.

      We also saw strong performance from some of our long-held bonds. These
bonds were issued when interest rates were much higher, with coupons at roughly
8%. That compares with newly issued bonds that have coupons in the 5.50% to
5.75% range. Not only did these older, higher-coupon bonds generally enjoy price
appreciation during the period, but they also helped to boost the Fund's income.

Strategy overview

Throughout the period, we focused on bonds with maturities of between 15 and 20
years. The yield spread -- the difference in yields between bonds of various
maturities -- was quite tight. In

[Bar chart with heading "Fund Performance" at top of left hand column. The chart
is scaled in increments of 2% from bottom to top, with 10% at the top and 0% at
the bottom. Within the chart there are three solid bars. The first represents
the 9.48% total return for John Hancock New York Tax-Free Income Fund Class A.
The second represents the 6.82% total return for the John Hancock New York
Tax-Free Income Fund Class B. The third represents the 8.93% total return for
the Average New York municipal bond fund. A footnote below states "The total
return for John Hancock New York Tax-Free Income Fund is at net asset value with
all distributions reinvested. The average New York municipal bond fund is
tracked by Lipper Analytical Services, Inc. (1). See the following two pages for
historical performance information. For Class A shares and the average New York
municipal bond fund, returns are for the year ended August 31, 1997. * For Class
B shares, return is from inception October 3, 1996 through August 31, 1997."]

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

our view, bonds with longer maturities didn't offer enough additional yield to
compensate for their added interest-rate sensitivity. So we chose
intermediate-maturity bonds where we thought the risk/return payoff was most
attractive. It was in the intermediate range that the muni market saw its
strongest demand and therefore best performance compared to longer-maturity
bonds.

      We also continued to emphasize non-callable securities, which can't be
redeemed by their issuer before their maturity. The upside to non-callable
securities is that they tend to perform better than callable securities (which
can be redeemed prior to maturity) when interest rates fall, and generally do no
worse than callable bonds when rates rise. Their downside is that they generally
offer less yield. During the period, non-callables offered about 10 basis points
(0.10%) less in yield on average than callable securities. However, we believed
that on a total return basis, non-callables were more attractive.

Outlook

For now, the economic backdrop appears favorable for municipal bonds. The
economy continues to look moderately strong, yet all appears to be quiet on the
inflationary front. However, we're not necessarily ruling out another small
interest rate boost. If the Federal Reserve Board sees something it believes
could be inflationary -- such as a stronger-than-expected employment report --
it's likely to act swiftly to curtail inflation before it becomes problematic.
But even a small, quarter-percentage point hike in interest rates probably
wouldn't the rattle the bond markets to a great extent. As for the New York
municipal market, we're optimistic. Given the recent strength of the state's
economy, we believe that eventually many New York municipal issuers could
receive higher credit ratings.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock New York Tax-Free Income Fund. Total return
is a performance measure that equals the sum of all income and capital gains
distributions, assuming reinvestment of these distributions, and the change in
the price of the Fund's shares, expressed as a percentage of the Fund's net
asset value per 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. Performance is affected by a 12b-1 plan.
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.

      Please note that a portion of the Fund's income may be subject to taxes,
and some investors may be subject to the Alternative Minimum Tax. Also note that
capital gains are taxable when distributed to shareholders.

Notes to Performance

(1)   Class A shares commenced operations on September 13, 1987.
(2)   Class B shares commenced operations on October 3, 1996. Since inception
      not annualized.
(3)   The Adviser has voluntarily reduced a portion of the management fee and a
      portion of the custodian fees have been reduced by balance credits during
      the period. Without the reductions of expenses, the average annual total
      returns for the one-year, five-year and since inception periods for Class
      A shares would have been 2.97%, 5.28% and 6.96%, respectively. The average
      annual total return since inception for Class B shares would have been
      (0.84%).

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

The charts on the right show how much a $10,000 investment in John Hancock New
York Tax-Free Income Fund would be worth on August 31, 1997. They assume that
you invested on the day each class of shares started. They also assume that you
have reinvested all distributions. For comparison, we've shown the same $10,000
investment in the Lehman Brothers Municipal Bond Index -- an unmanaged index
that includes approximately 15,000 bonds and is commonly used as a measure of
bond performance.

ACCOUNTING POLICIES

1940. The Trust consists of two series: John Hancock New York Tax-Free Income
Fund (the "Fund") and John Hancock Massachusetts Tax-Free Income Fund. The other
series of the Trust is reported in separate financial statements. The investment
objective of the Fund is to provide as high a level of current income exempt
from both federal income taxes and New York personal income taxes as is
consistent with preservation of capital.

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A and Class B 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. On October 3, 1996, Class B shares of beneficial interest were sold to
commence class activity.

      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
investment, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $292,545 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. To the extent such carryforwards are used by the
Fund, no capital gains distribution will be made. The carryforwards expire as
follows: August 31, 2003 -- $75,132 and August 31, 2004 -- $217,413.
Additionally, net capital losses of $62,129 attributable to security
transactions occurring after October 31, 1996 are treated as arising on the
first day (September 1, 1997) of the Fund's next taxable year.

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.

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

              John Hancock Funds -- New York Tax-Free Income Fund

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 time of disposition.

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 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 that 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 relative
sizes 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. The Fund had no borrowing
activity for the period ended August 31, 1997.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts 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 will be 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 on 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," will be 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
fluctuation imposed by an exchange.

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

      At August 31, 1997, there were no open positions in financial futures
contracts.

OPTIONS Listed options will be valued at the last quoted sales price on the
exchange on which they are primarily traded. Purchased put or call
over-the-counter options will be valued at the average of the "bid" prices
obtained from two independent brokers. Written put or call over-the-counter
options will be valued at the average of the "asked" prices obtained from two
independent brokers. Upon the writing of a call or put option, an amount equal
to the premium received by the Fund will be included in the Statement of Assets
and Liabilities as an asset and corresponding liability. The amount of the
liability will be subsequently marked to market to reflect the current market
value of the written option.

      The Fund may use option contracts to manage its exposure to the price
volatility of financial instruments. Writing puts and buying calls will tend to
increase the Fund's exposure to the underlying instrument and buying puts and
writing calls will tend to decrease the Fund's exposure to the underlying
instrument, or hedge other Fund investments.

      The maximum exposure to loss for any purchased options will be limited to
the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual expo-

sure will be limited to the change in value of the contract over the period the
contract remains open.

      Risks may also arise if counterparties do not perform under the contract's
terms ("credit risk"), or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit and liquidity risks in over-the-counter option contracts, the Fund will
continuously monitor the creditworthiness of all its counterparties.

      At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's period-end
Statement of Assets and Liabilities.

      There were no written option transactions for the period ended August 31,
1997.

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) 0.500% of the first $250,000,000 of the
Fund's average daily net asset value, (b) 0.450% of the next $250,000,000, (c)
0.425% of the next $500,000,000, (d) 0.400% of the next $250,000,000 and (e)
0.300% of the Fund's average daily net asset value in excess of $1,250,000,000.

      The Adviser has voluntarily agreed to limit the Fund's expenses further to
the extent required to prevent expenses from exceeding 0.70% and 1.40% of the
average net assets attributable to Class A and Class B, respectively.
Accordingly, for the period ended August 31, 1997, the reduction in the
Adviser's fee collectively with any additional amounts not borne by the Fund by
virtue of the expense limit amounted to $222,709. This limitation may be
discontinued at any time.

      The Fund has an agreement with its custodian bank under which $5,779 of
custodian fees have been reduced by balance credits applied during the period
ended August 31, 1997. If the Fund had not entered into this agreement, the
assets not invested, on which these balance credits were earned, could have
produced taxable income.

      The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the period ended August
31, 1997, net sales charges received with regard to sales of Class A shares
amounted to $155,262. Out of this amount, $20,879 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $36,663
was paid as sales commissions to unrelated broker-dealers and $97,720 was paid
as sales commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

      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 for providing distribution- related services to the Fund in
connection with the sale of Class B shares. For the period ended August 31, 1997
the contingent deferred sales charges received by JH Funds amounted to $2,301.

      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 and Class B 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 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 Funds. 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., 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 August 31, 1997, the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $416.

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 August 31, 1997, aggregated $25,824,964 and $26,925,359, respectively.
There were no purchases or sales of obligations of the U.S. government and its
agencies during the period ended August 31, 1997.

      The cost of investments owned at August 31, 1997 for federal income tax
purposes was $51,913,970. Gross unrealized appreciation and depreciation of
investments aggregated $3,905,197 and $730, respectively, resulting in net
unrealized appreciation of $3,904,467.

NOTE D -
Reclassification of accounts

During the year ended August 31, 1997, the Fund has reclassified amounts to
reflect an increase in accumulated net realized loss on investments of $16,553,
an increase in undistributed net investment income of $16,632 and a decrease in
capital paid-in of $79. This represents the amount necessary to report these
balances on a tax basis, excluding certain temporary differences, as of August
31, 1997. 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 certain differences in the computation of
distributable income and capital gains under federal tax rules versus generally
accepted accounting principles. The calculation of net investment income per
share in the financial highlights excludes these adjustments.

REPORT OF INDEPENDENT AUDITORS
To the Shareholders and Board of Trustees of
John Hancock New York Tax-Free Income Fund

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments (except for credit ratings and yields at market),
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 the New York Tax-Free Income Fund (the "Fund") at August 31, 1997,
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 significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at August 31, 1997 by
correspondence with the custodian provide a reasonable basis for the opinion
expressed above.
