      DEAR FELLOW SHAREHOLDERS: 

The stock market astounded many in 1997 by producing a record-breaking third
straight year of 20%-plus returns. Bond investors also enjoyed the benefits of a
strong economy with no inflation. After such a remarkable performance, many are
wondering what the markets will do for an encore in 1998.

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

      Within the first two months of the year, we saw two different sides of the
market. In January, the market underwent rapid mood swings and barely advanced
at all. While news on the domestic inflation and economic fronts remained good,
investors were still trying to determine how much of the Asian financial crisis
would filter through the U.S. economy and corporate profits. Each week, it
seemed, investors either had on their rose-colored glasses or had taken them
off. Then in February, fears apparently dissipated, and the market rallied to
new all-time highs by the month's end.

      In the face of such fluctuations, a trusted investment professional can be
your best ally. Now, more than ever, your investment professional can help you
take the emotion out of investment decisions. At a time when your instincts
might have you react to the heat of the market's moment, your investment
professional can serve as an objective voice to put current events in a
longer-term perspective. He or she can also help you evaluate your investments
in any market environment to ensure that they fit your risk tolerance and time
horizons. On an ongoing basis, your investment professional is there for you to
check out new investment ideas or to get an informed opinion about current
economic and market conditions.

      We encourage you to take advantage of this important resource. Working
together, you can draw up a detailed road map to help reach your financial
destination regardless of the conditions along the way.

Sincerely,

/s/ EDWARD J. BOUDREAU, JR.

             Municipal bonds perform well, despite supply pressures
            
Municipal bond investors continued to reap the benefits of a healthy bond market
during the last six months. Tame inflation and falling interest rates were the
key market drivers, pushing bond prices up and yields down. The financial crisis
in Southeast Asia also buoyed the bond market, particularly in the fourth
quarter of 1997. As worries about Asia's financial woes heightened, more
investors sought out a "safe haven" in U.S. bonds, particularly Treasuries.

      Municipal bonds, however, had trouble keeping up with U.S. Treasuries in
the latest bond market rally because of the significant increase in new issues.
In order to take advantage of lower interest rates, more local governments have
been issuing new tax-exempt bonds. In fact, 1997 was the third most prolific
year of new issues ever in the municipal market. This flood of new issuance in
the last quarter of 1997 increased pressure on the municipal market, causing
them to lag Treasuries during the period.

      Even with the supply pressures, municipal bonds turned in a strong
performance during the period. John Hancock Massachusetts Tax-Free Income Fund's
Class A and Class B shares returned 5.42% and 5.05%, respectively, at net

from this if you were not invested in the Fund for the entire period and did not
reinvest all distributions. The Fund's returns were in line with the average
Massachusetts fund's return of 5.06%, according to Lipper Analytical Services,
Inc. (1) Please see pages six and seven for longer-term performance information.

Uninsured holdings buoy performance

By far, the most important trend in the municipal market continues to be the
collapse of credit spreads. All that means is that the difference in yield
between bonds with different credit ratings has narrowed considerably. There are
a few reasons for this phenomenon. First, with far more credit upgrades than
downgrades in the market, there's very little concern about credit risk -- that
is, the ability of a municipality to make good on its debt. What's more, because
roughly 70% of the new issues coming to market are insured, the supply of
uninsured bonds with higher yields has become more scarce. At the same time,
however, demand for these higher-yielding issues has remained strong.
Accordingly, their prices have risen and yields have fallen -- closing the yield
gap between insured and uninsured bonds. 

      The Fund has benefited tremendously from this compression in credit
spreads, thanks to its strong holdings in uninsured bonds. Through in-depth
credit analysis, we have been able to identify uninsured bonds with not only
attractive yields, but also solid fundamentals and improving credit profiles.
One of our best performers was New England Baptist Hospital. Its merger with
Pathway Network, Inc. resulted in its credit upgrade, which enabled it to
restructure its debt and has driven its strong performance during the last six
months.

Portfolio duration and structure

Throughout the period, we continued to carefully manage the portfolio's
duration. Duration is a measure of how sensitive a fund's share price is to
interest-rate changes. The shorter the duration, the less sensitive the share
price is to changes in interest rates. During last summer and fall, we extended
the Fund's duration, which allowed us to reap the benefits of the bond market's
rally. More recently, however, we've moved to a more neutral stance, given the
market's strong upward move and the uncertainty surrounding the direction of the
U.S. economy.

   Our long-time focus on call protection has also continued. As you may
remember from previous reports, call protection protects a bond from being
redeemed early by its issuer for a

certain period of time. Good call protection is especially important in a
falling interest-rate environment. That's because if a bond gets called away --
or redeemed -- early, investors are forced to reinvest their money in bonds with
lower yields. By focusing on issues with strong call protection, we've been able
to maintain the Fund's competitive yields.

Outlook

Looking ahead, we're optimistic about the prospects for the Massachusetts
municipal bond market. The economy continues to grow at a steady pace with low
unemployment and a strong real estate market. The state is also spending heavily
to improve its infrastructure. The Central Artery Project in downtown Boston is
moving forward, and we're likely to see increased issuance as the state
continues to fund this project. We've also seen new issuance from other state
entities such as the Massachusetts Water Authority and the Massachusetts Health
and Education Agency. After the scarcity of new issues in the state in the past
few years, this new supply is a welcome change, providing some attractive
opportunities for investors.

      The macro-economic environment is also favorable for municipal bonds. The
Federal Reserve has been vigilant about keeping a lid on inflation and there's
no reason to believe that will change in the near future. The biggest question
is whether Asia's economic turmoil will slow the U.S. economy. Until the impact
becomes more clear, we are likely to see the Fed put their interest-rate policy
on hold, and the bond market continue to trade in a narrow range. However, we
firmly believe that there's little risk of inflation. If anything, Asia's
financial woes will have a moderating effect on the U.S. economy, which should
help keep inflation in check. Against that backdrop, bonds should continue to
perform well.

      Supply pressures in the municipal market are likely to continue through
the first part of 1998 as state and local governments continue to take advantage
of the low interest-rate environment. However, we view this market pressure as a
great buying opportunity. With many municipal bonds now trading at attractive
valuations, we're looking for opportunities to add new issues to the portfolio,
especially those with strong call protection.

"...we're optimistic about the prospects
for the Massachusetts municipal bond market."

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

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 measures the change in value of an investment from the beginning to the
end of a period, assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 4.50%. Class B performance reflects a maximum contingent deferred
sales charge (maximum 5% and declining to 0% over six years).

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.

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 (AMT). Also note
that capital gains are taxable.

             John Hancock Funds - Massachusetts Tax-Free Income Fund

(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Tax-Exempt Series Trust (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,
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.

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 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 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 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. These agreements enable
the Fund to participate with other Funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $600 million,
collectively. Interest is charged to each Fund, based on its borrowings, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at a
rate of 0.075% per annum based on the average daily unused portion of the line
of credit, is allocated among the participating Funds. The Fund had no borrowing
activity for the period ended February 28, 1998.

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's gains and/or losses can be affected as a result of futures contracts.

      At February 28, 1998, open positions in financial futures contracts were
as follows:

                                                        UNREALIZED

      At February 28, 1998, the Fund has deposited $40,000 in a segregated
account to cover margin requirements on open financial futures contracts.

OPTIONS The Fund may purchase options contracts. 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 options 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 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 options 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 February
28, 1998.

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 February 28, 1998, 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 $113,786. This limitation may be
discontinued at any time.

      The Fund has an agreement with its custodian bank under which $2,724 of
custodian fees have been reduced by balance credits applied during the period
ended February 28, 1998. 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 February
28, 1998, net sales charges received with regard to sales of Class A shares
amounted to $73,285. Out of this amount, $8,497 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $46,605
was paid as sales commissions to unrelated broker-dealers and $18,183 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 February 28,
1998 the contingent deferred

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

             John Hancock Funds - Massachusetts Tax-Free Income Fund

sales charges received by JH Funds amounted to $1,941.

      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 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
0.30% 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 period 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 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 February 28, 1998 the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $409.

DEAR FELLOW SHAREHOLDERS: 

The stock market astounded many in 1997 by producing a record-breaking third
straight year of 20%-plus returns. Bond investors also enjoyed the benefits of a
strong economy with no inflation. After such a remarkable performance, many are
wondering what the markets will do for an encore in 1998.

      Within the first two months of the year, we saw two different sides of the
market. In January, the market underwent rapid mood swings and barely advanced
at all. While news on the domestic inflation and economic fronts remained good,
investors were still trying to determine how much of the Asian financial crisis
would filter through the U.S. economy and corporate profits. Each week, it
seemed, investors either had on their rose-colored glasses or had taken them
off. Then in February, fears apparently dissipated, and the market rallied to
new all-time highs by the month's end.

            Credit upgrades, benign inflationary environment mark the
                   New York municipal market's six-month rise

The past six months were a strong period for New York's municipal bond market,
punctuated by credit upgrades of municipal debt issued by the state, some of its
agencies and New York City. The higher credit ratings, which are measures of
those issuers' ability to pay back their debt, came in recognition of the
state's and city's improving fiscal and economic condition. That improvement, in
turn, owes a lot to the boom on Wall Street, which has generated billions of
dollars in tax revenues in recent years.

   The credit upgrades only added to what was an increasingly favorable
environment for municipal bonds. At the beginning of the period, U.S. economic
growth was strong, igniting investors' concerns that inflation could be on the
upswing. Bond investors dislike inflation because it cuts into the value of
their fixed income payments. In light of the inflationary worries, bond yields
stayed stubbornly high -- and bond prices low -- in the late summer and early
fall of 1997. But absent any evidence that consumer prices and wages -- two main
inflationary ingredients -- were on the rise to any marked degree, investors
began to reward bonds by pushing bond yields lower and prices higher in October.
From the end of that month through the end of 1997, bonds got an added boost
from the expanding

economic crisis in Southeast Asia. With continued economic growth there in
doubt, investors not only fled the region's equity and bond markets, but many
also pulled money away from the U.S. stock market. This so-called "flight to
safety" brought more money into the U.S. bond market, further pushing municipal
bond prices higher throughout much of the remainder of the period.

      Against this favorable backdrop, John Hancock New York Tax-Free Income
Fund's performance was strong on both an absolute and relative basis. For the
six-month period ended February 28, 1998, the Fund's Class A and Class B shares
posted total returns of 5.11% and 4.74%, respectively, at net asset value. Keep
in mind that your net asset value return will be different from the Fund's if
you were not invested in the Fund for the entire period and did not reinvest all
distributions. Those returns were in line with the 4.87% return for the average
New York municipal bond fund for the same period, according to Lipper Analytical
Services, Inc. (1) Longer-term performance information can be found on pages six
and seven.

Leaders and laggards

Some of our best performers were bonds with good call protection. Bond issuers,
like homeowners with mortgages, often like the option of refinancing -- or
"calling" -- their debt when interest rates fall as a way to reduce their debt
service costs. Although calling a bond is good for the issuer, it can be bad for
the bond holder who may be forced to reinvest the proceeds at lower interest
rates. Non-callable bonds, on the other hand, can't be redeemed by their issuer
before maturity. Not only do non-callable bonds generally fare better than
callable bonds when interest rates are falling, they typically perform no worse
than callable securities when interest rates rise. Bonds with good call
protection have relatively long call dates -- meaning they can't be redeemed for
a relatively long period. During the period, they performed well compared to
their callable counterparts.

   Other good performers included bonds with relatively high yields, including
those issued by New York City. As bond yields fell, yield-hungry investors
increasingly sought out the higher-yielding sectors of the municipal market,
including general obligation bonds (GOs) issued by the city. As demand for them
grew and investors began to anticipate a credit upgrade for the city's debt, New
York City GO prices rallied. The earlier upgrade of the state's and some of its
agencies' debt also helped boost the prices of our holdings in New York State
Dormitory Authority

and New York State Medical Care Facilities.

      Despite all the good news, we had some disappointments. Advance-refunded
bonds didn't perform well and we cut back our stake in them. In an
advance-refunding, an issuer with existing bonds will issue a second set of
bonds. Proceeds from this sale are then invested in U.S. Treasury securities,
and the Treasuries then secure the original bonds until their call date. In this
case, our advance-refunded bonds were backed by short-term, high-quality U.S.
Treasury securities. Because short-maturity securities didn't fare nearly as
well as intermediate- and long-maturity bonds during the past six months, our
advance-refunded holdings proved to be disappointing.

Outlook

In our view, New York City has done a commendable job of managing its finances,
in particular by not just counting on a continuation of Wall Street's recent
success to fund increased spending in the coming years. We think this fiscal
conservatism bodes well for the future of the city's municipal debt. As far as
the state goes, we're reasonably optimistic, but we would feel even more
comfortable if the legislature managed to pass a responsible budget on a timely
basis.

      Our outlook for the municipal bond market in general is reasonably good,
based on the fact that we don't see interest rates rising over the near term.
Inflation continues to remain subdued with no evidence that it will be a problem
over the short term. Furthermore, we think that the problems in Southeast Asia
will translate into slower growth here in the United States, helping to keep a
lid on any brewing inflationary pressures.

      Without inflation, we should see stable or falling interest rates,
providing a favorable backdrop for municipals.

"...we don't see interest rates rising over the near term."

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

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
measures the change in value of an investment from the beginning to the end of a
period, assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 4.50%. Class B performance reflects a maximum contingent deferred
sales charge (maximum 5% and declining to 0% over six years).

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.

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 (AMT). Also note
that capital gains are taxable.

    shares would have been 4.17%, 5.69% and 6.99%, respectively. The average
    annual total returns for the one-year period and since inception for Class
    B shares would have been 3.28% and 4.16%, repectively.

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

               John Hancock Funds - New York Tax-Free Income Fund

(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Tax-Exempt Series Trust (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 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,
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. 

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 $284,067 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 -- $66,654 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, INTEREST AND DISTRIBUTIONS 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

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

               John Hancock Funds - New York Tax-Free Income Fund

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 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 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 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. These agreements enable
the Fund to participate with other Funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $600 million,
collectively. Interest is charged to each Fund, based on its borrowings, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at a
rate of 0.075% per annum based on the average daily unused portion of the line
of credit, is allocated among the participating Funds. The Fund had no borrowing
activity for the period ended February 28, 1998.

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's gains and/or losses can be affected as a result of futures contracts.

      At February 28, 1998, there were no open positions in financial futures
contracts.

OPTIONS The Fund may purchase options contracts. 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 options 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 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 options 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 February
28, 1998.

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 February 28, 1998, 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 $115,631. This limitation may be
discontinued at any time.
 
      The Fund has an agreement with its custodian bank under which $1,914 of
custodian fees have been reduced by balance credits applied during the period
ended February 28, 1998. 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 February
28, 1998, net sales charges received with regard to sales of Class A shares
amounted to $49,035. Out of this amount, none was retained and used for printing
prospectuses, advertising, sales literature and other purposes, $49,035 was paid
as sales commissions to unrelated broker-dealers and none 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 February 28,
1998 the contingent deferred sales charges received by JH Funds amounted to
$6,334.

      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 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
0.30% of Class A average daily net assets and 1.00% of Class B average daily net
assets, to reimburse

               John Hancock Funds - New York Tax-Free Income Fund

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 period 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 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 February 28, 1998 the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $416.
