DEAR FELLOW SHAREHOLDERS:

Over the last 12 months, the market's advances were restricted to an
increasingly select group of stocks - primarily in the technology and
communications areas. Even those gains were accompanied by tremendous levels of
daily volatility. But many other stocks, including the household blue-chip
names, fell in response to a tough combination of investor apathy, rising
interest rates and earnings concerns.

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

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

In this same period, bonds struggled through one of their worst years in more
than two decades, as the strength of the U.S. economy and the rebound of many
others around the world provoked inflation fears. Though their longer-term
outlook looks brighter, in many instances bond mutual fund investors have
actually lost a little ground or made only slight advances lately.

While we expect the market to broaden eventually, we also expect more
volatility. More than ever, this type of environment calls for investment
diversification. Since not all parts of your portfolio will perform equally well
all the time, we believe it is important to allocate your assets among different
types of investments and funds that target a variety of market segments. This
strategy, executed under the guidance of a seasoned investment professional,
could provide you with a better chance of both realizing results and weathering
the market's changing conditions.

The market's disappointingly narrow focus has created a widening gap in
investment performance. Keep that in mind as you read the report from your
fund's portfolio management team on the following pages. It's all too easy to
get caught up in the headlines and miss what lies underneath.

Sincerely,

/s/Maureen R. Ford

                  Climbing interest rates hurt municipal bonds
                  --------------------------------------------

It has been a rough road for municipal bonds over the last six months as the
Federal Reserve continued to raise interest rates in an attempt to put the
brakes on inflationary pressures and an overheating economy. Although some
commodity prices such as oil have spiked up, overall inflation still appears to
be under control. Nonetheless, the Federal Reserve's preemptive interest-rate
hikes drove bond prices down during the period.

         Also adding to the downward pressure on municipal bonds was the lack of
liquidity in the market. Cash flow into municipal bonds virtually dried up as
investors became disenchanted with falling bond prices and were enticed into the
stock market by higher returns.

Fund performance

Given the market backdrop, municipal bonds posted disappointing returns for the
period. For the six months ended February 29, 2000, John Hancock Massachusetts
Tax-Free Income Fund's Class A, Class B and Class C shares returned -1.13%,
- -1.48% and -1.48%, respectively, at net asset value. By comparison, the average
Massachusetts municipal bond fund returned -1.21% for the same period, according
to Lipper, Inc.1 Keep in mind that your net asset value return will be different
from the Fund's performance if

Performance scorecard

In this difficult environment, the Fund benefited from managing the
interest-rate sensitivity - or duration - of the portfolio. The shorter the
duration, the less sensitive the Fund will be to interest-rate changes. From
September through December, we shortened the Fund's duration, which protected
the Fund when rates climbed in the back half of the year. We began to cautiously
push out the Fund's duration to a neutral position at the start of this year
since, although there are still more rate hikes to come, a goodly portion is
already priced into the market.

         On the negative side, the Fund's health-care holdings were a
disappointment. Federal reductions

in Medicare and Medicaid reimbursements turned out to be more severe than
industry experts - and even the government - had anticipated. In fact,
Massachusetts' largest HMO, Harvard Pilgrim Health (HPH) shocked the market in
December by reporting significantly higher-than-expected losses, due to
accounting problems. As a result, the state put HPH into protective receivership
to enable a workout plan to be developed. This development had a negative impact
on the state's health-care names. While the Fund does own HPH, our holdings were
insured and carried a AAA rating. Therefore, even if the issuer were to default,
full and timely payment of the debt is insured by a AAA-rated insurance agency.

Restructuring  the portfolio

It's important to remember, especially in a tough market, that bond prices will
eventually turn around. So it's critical to maintain a long-term investment
perspective and to consistently focus on positioning the Fund for the future.
Given that, we've taken advantage of rising interest rates and the downturn in
the municipal bond market to begin gradually restructuring the portfolio.

         To start, the jump in interest rates has allowed us to trade some of
our lower-yielding bonds for higher-yielding ones, improving the overall yield
of the portfolio. Second, we've also continued to improve the Fund's call
protection. Call protection guards against a bond's being redeemed by the issuer
for a certain period of time. Good call protection is important when interest
rates are falling, because issuers often try to refinance their bonds at lower
interest rates. If a bond gets "called away," or redeemed early, then investors
are forced to reinvest their money in bonds with lower yields. Weak bond markets
are good for the disciplined investor, because negative price

action often diverts attention from factors like coupon structure and call
protection. It is the perfect time to add long-term value at inexpensive levels.

         While rates have recently been on the rise, overall inflation is still
very contained by historical standards. A proactive Fed has proven to be a boon
to bond investors over time. As they say, what goes up, comes back down. When
rates do, the Fund will be well positioned with strong call protection.

State status

The Massachusetts economy is still growing strongly and the state has built a
nice surplus. However, Massachusetts is now facing some fiscal challenges. As
mentioned earlier, health-care reimbursements remain under pressure, and
legislators are starting to look at ways to provide additional relief. What's
more, the state's highway and tunnel project, known as the "Big Dig," has
recently encountered budget overruns. The state has until late March to develop
a financing plan acceptable to the federal government, or face the prospect of
reduced federal funding for transportation needs.

Bond outlook

In the short-term, bond investors could be in for a bumpy ride. The Federal
Reserve has clearly indicated that it is concerned about an overheating economy
and budding inflation. Given that, we believe that the Federal Reserve is likely
to stay focused on interest rates. Concerns about rising rates are likely to
keep investors nervous and the bond market volatile in the near term.

         As for municipal bonds, the technical conditions are improving. For
starters, the supply/demand factors in the municipal market are improving. In
1999, new issuance dropped 25%. So far in 2000, it's down roughly 40%. As demand
for municipal bonds begins to pick up, they will be harder to come by and that
is likely to drive prices higher.

         In addition, higher interest rates will eventually put a damper on the
economy's strong growth. When that happens, we are likely to see interest rates
peak and eventually resume their decline. Our discipline is to stay fully
invested, and we will continue to restructure the portfolio so that it is well
positioned when the market does turn the corner.

                             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 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). Class C
performance includes a contingent deferred sales charge (1% declining to 0%
after one year).

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

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.

Notes to Performance

(1) The Adviser has voluntarily reduced a portion of the management fee
    and a portion of the custodian fee has 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 ten-year periods
    for Class A shares would have been (8.84%), 4.99% and 5.37%,
    respectively. The average annual total returns for the one-year period
    and since inception for Class B shares would have been (9.76%) and
    2.48%, respectively. The total return since inception for Class C
    shares would have been (6.37%). Without the reductions of expenses, the
    yield for Class A, Class B and Class C shares would have been 4.67%,
    4.21% and 4.21%, respectively.

           John Hancock Funds - Massachusetts Tax - Free Income Fund

(UNAUDITED)

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

Significant accounting policies of the Fund are as follows:

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

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. 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 $185,328 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 - $41,406, August 31, 2004 - $137,277 and August 31,
2005 - $6,645.

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 the time of disposition.

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

           John Hancock Funds - Massachusetts Tax - Free Income Fund

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. The Fund has entered into
a syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the period ended February 29, 2000.

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.

         There were no open positions in financial futures contracts for the
period ended February 29, 2000.

OPTIONS The Fund may purchase or sell options contracts. Listed options will be
valued at the last quoted sales price on the exchange on which they are
primarily traded. Over-the-counter options are valued at the mean between the
last bid and asked prices. 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,

                                       19

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

           John Hancock Funds - Massachusetts Tax - Free Income Fund

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 options transactions for period ended February
29, 2000.

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.

         Effective January 1, 2000, the Adviser has voluntarily agreed to limit
the Fund's expenses to the extent required to prevent expenses from exceeding
0.80%, 1.50% and 1.50% of the average net assets attributable to Class A, Class
B and Class C, respectively. Prior to January 1, 2000, the expense limitations
were 0.80%, 1.50% and 1.50% of the average net assets attributable to Class A,
Class B and Class C, respectively. Prior to January 1, 2000, the expense
limitations were 0.70%, 1.40% and 1.40% of the average net assets attributable
to Class A, Class B and Class C, respectively. Accordingly, for the period ended
February 29, 2000, 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 $115,598. This limitation may not be discontinued until December 31,
2000.

         The Fund has an agreement with its custodian bank under which $4,221 of
custodian fees have been reduced by balance credits applied during the period
ended February 29, 2000. 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 29, 2000, net sales charges received with regard to sales of Class A
shares amounted to $40,570. Out of this amount, $8,461 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $1,762
was paid as sales commissions to unrelated broker-dealers and $30,347 was paid
as sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Life Insurance Company ("JHLICo"), is the indirect sole shareholder of
Signator Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended February 29,
2000 the contingent deferred sales charges received by JH Funds amounted to
$20,861.

         Class C shares which are redeemed within one year of purchase will be
subject to a CDSC at a rate of 1.00% of the lesser of the current market value
at the time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from the CDSC are paid to JH Funds

and are used in whole or in part to defray its expenses for providing
distribution related services to the Fund in connection with the sale of Class C
shares. There were no contingent deferred sales charges received by JH Funds for
the period ended February 29, 2000.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C 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 and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

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

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

         Mr. Stephen L. Brown, Ms. Maureen R. Ford, Ms. Anne C. Hodsdon and Mr.
Richard S. Scipione are directors and/or officers of the Adviser and/or its
affiliates, as well as Trustees of the Fund. The compensation of unaffiliated
Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer, for
tax purposes, their receipt of this compensation under the John Hancock Group of
Funds Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation liability
are recorded on the Fund's books as an other asset. The deferred compensation
liability and the related other asset are always equal and are marked to market
on a periodic basis to reflect any income earned by the investment as well as
any unrealized gains or losses. The investment had no impact on the operation of
the Fund.

NOTE C -

DEAR FELLOW SHAREHOLDERS:

Over the last 12 months, the market's advances were restricted to an
increasingly select group of stocks - primarily in the technology and
communications areas. Even those gains were accompanied by tremendous levels of
daily volatility. But many other stocks, including the household blue-chip
names, fell in response to a tough combination of investor apathy, rising
interest rates and earnings concerns.

In this same period, bonds struggled through one of their worst years in more
than two decades, as the strength of the U.S. economy and the rebound of many
others around the world provoked inflation fears. Though their longer-term
outlook looks brighter, in many instances bond mutual fund investors have
actually lost a little ground or made only slight advances lately.

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

While we expect the market to broaden eventually, we also expect more
volatility. More than ever, this type of environment calls for investment
diversification. Since not all parts of your portfolio will perform equally well
all the time, we believe it is important to allocate your assets among different
types of investments and funds that target a variety of market segments. This
strategy, executed under the guidance of a seasoned investment professional,
could provide you with a better chance of both realizing results and weathering
the market's changing conditions.

The market's disappointingly narrow focus has created a widening gap in
investment performance. Keep that in mind as you read the report from your
fund's portfolio management team on the following pages. It's all too easy to
get caught up in the headlines and miss what lies underneath.

Sincerely,

/s/Maureen R. Ford

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

Municipal bonds, like most bonds, slumped during the past six months in response
to rising interest rates, inflation fears and flagging demand. Prior to the
beginning of the period, the Federal Reserve had raised interest rates on two
separate occasions to fight potential inflationary pressures resulting from very
strong U.S. economic growth and recovering economies overseas. While inflation
remained virtually non-existent throughout the fall of 1999, inflation concerns
and the prospects for further interest- rate hikes continued to worry bond
investors. They reacted to these worries by pushing bond yields higher and their
prices - which move in the opposite direction of yields - lower.

         Throughout the period, there weren't any conclusive signs that
inflation was on the rise. But the global economy's increasing strength and
rising oil prices sparked fears that the Fed would continue to push interest
rates a lot higher to contain inflation. Those fears proved warranted when the
Fed raised interest rates in November 1999 and again in February 2000. Municipal
bond yields rose accordingly, and their prices fell.

         In addition to rising interest rates, bonds faced another challenge.
They held little appeal for many investors who were bent on finding fast revenue
growth among high-flying technology stocks. Furthermore, municipals experienced
relatively heavy selling in late 1999 when some institutional investors, who
routinely seek out the most attractive values among various

fixed-income investments, shunned municipals in favor of beaten-down corporate
bonds.

         As difficult as it was, the period did contain a silver lining or two.
First, the strong U.S. economy helped boost the tax collections and revenues of
municipal issuers across the state. Second, rising municipal bond yields began
to attract individual investors. For an investor in the top combined state and
federal tax bracket of roughly 50%, a 30-year AAA-rated municipal bond issued in
New York that yielded 5.95% on February 29, 2000, offered a tax-equivalent yield
of approximately 11.9%.

Fund performance

For the six-month period ended February 29, 2000, John Hancock New York Tax-Free
Income Fund's Class A, Class B and Class C shares posted total returns of
- -0.89%, -1.23% and -1.23%, respectively, at net asset value. By comparison, the
average New York municipal bond fund

value return will be different from the Fund's performance if you were not
invested in the Fund for the entire period and did not reinvest all
distributions. Please see pages six and seven for longer-term performance
information.

Defensive stance

Our somewhat defensive posture aided performance during this difficult period.
Throughout much of the past six months, we maintained a relatively short
duration, which helped the Fund's share price fall less when interest rates
rose. In addition, the Fund had a somewhat defensive credit-quality positioning,
with a larger exposure to higher-quality bonds than many of its competitors.
Many of the lowest-quality, less liquid bonds proved to be especially vulnerable
to unfavorable market conditions.

         Our focus on premium-coupon bonds was also a plus. Premium coupons pay
interest rates above prevailing market rates and trade at prices that are above
their face - or par - value. Their high levels of income helped cushion them
against price declines caused by rising interest rates. This was especially
helpful in a period when many municipal bonds' prices fell so much that they
started to lose eligibility for the more favorable capital gains tax treatment
known as de minimis. As market conditions subjected more and more bonds to this
obscure tax pitfall, it placed further pressure on these bonds that fell outside
of de minimis.

Leaders and laggards

Virtually all of our holdings came under pressure from rising interest rates,
although some hung in better than others. For instance, we saw good performance
from bonds issued by the New York Transitional Funding Authority, which

we purchased at very attractive prices and were helped by relatively strong
demand. On the flip side, health-care bonds as a group were among the municipal
market's worst performers. Concerns about cutbacks in federal Medicare and
Medicaid payments in response to the Balanced Budget Act of 1997 raised
questions about the industry's long-term profitability. In addition, the refusal
of municipal-bond insurers to insure lower-quality tiers of the hospital sector
also weighed heavily on the group.

Shift toward economically resilient bonds

As the period wore on, we added more bonds from issuers that are less
economically sensitive, such as essential services including water and sewer. In
our view, the economy will eventually slow, which might put pressure on general
obligation bonds and others backed by tax revenues. Since economically sensitive
bonds offered only slight amounts, if any, of additional yield, we weren't
penalized for getting some measure of protection in the event of an economic
slowdown.

Outlook

In our view, the Federal Reserve policymakers will probably need to push
short-term interest rates even higher to contain inflation. Inflation and
interest-rate prospects are likely to continue to worry bond investors. Even
though broad gauges of inflation so far have remained relatively stable, the
economy remains quite strong and the price of oil has risen rapidly.
Furthermore, the Fed has warned about the impact surging stock prices are having
on the economy. That's why we plan to maintain the Fund's current defensive
posture of a somewhat short duration in the near term.

         Ultimately, however, we believe that investors will begin to anticipate
the end of the Fed's campaign to keep inflation in check. When that occurs -
probably in the second half of this year - we expect that market conditions will
improve and bonds will be poised for better performance. Once we're comfortable
that that's the case, we will consider extending the Fund's duration in order to
take advantage of stable or falling interest rates. As for New York City, while
its fiscal and economic fortunes presently are quite good, it is still highly
dependent on the health of Wall Street and the general economy. The state has
enjoyed a series of credit upgrades in recognition of its strong economy and
prudent fiscal management. With that in mind, we'll continue to seek out
opportunities to buy economically resilient types of bonds that offer attractive
yields and insulation from a slower economy.

                             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
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). Class C
performance includes a contingent deferred sales charge (1% declining to 0%
after one year).

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

Please read your prospectus carefully before you invest or send money. 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.

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

The charts on the right show how much a $10,000 investment in the John Hancock
New York Tax-Free Income Fund would be worth, assuming all distributions were
reinvested for the period indicated. For comparison, we've shown the same
$10,000 investment in the Lehman Brothers Municipal Bond Index - an unmanaged
index that includes approximately 15,000 bonds and is commonly used as a measure
of bond performance. It is not possible to invest in an index. Past performance
is no guarantee of future results.

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

               John Hancock Funds - New York Tax-Free Income Fund


(UNAUDITED)

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

         Significant accounting policies of the Fund are as follows:

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

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. 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.

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.

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

               John Hancock Funds - New York Tax-Free Income Fund

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

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

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund entered into a
syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks, which permit borrowings of up to $500 million,
collectively. Interest is charged to each fund based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the period ended February 29, 2000.

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 to and from the
broker, known as "variation margin," 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 29, 2000, there were no open positions in financial futures
contracts.

OPTIONS The Fund may purchase or sell options contracts. Listed options will be
valued at the last quoted sales price on the exchange on which they are
primarily traded. Over-the-counter options will be valued at the mean between
the last bid and asked prices. 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 year-end
Statement of Assets and Liabilities.

         At February 29, 2000, there were no written option transactions.

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.

         Effective January 1, 2000, the Adviser has voluntarily agreed to limit
the Fund's expenses to the extent required to prevent expenses from exceeding
0.80%, 1.50% and 1.50% of the average net assets attributable to Class A, Class
B and Class C, respectively. Prior to January 1, 2000, the expense limitations
were 0.70%, 1.40% and 1.40% of the average net assets attributable to Class A,
Class B and Class C, respectively. Accordingly, for the period ended February
29, 2000, 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
$90,887. This limitation may not be discontinued until December 31, 2000.

         The Fund has an agreement with its custodian bank under which $13,333
of custodian fees have been reduced by balance credits applied during the period
ended February 29, 2000. 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 29, 2000, net sales charges received with regard to sales of Class A
shares amounted to $14,146. Out of this amount, $2,725 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $4,313
was paid as sales commissions to unrelated broker-dealers and $7,108 was paid as
sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. The Adviser's indirect parent, John Hancock Life Insurance
Company ("JHLICo"), is the indirect sole shareholder of Signator Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended February 29,
2000, the contingent deferred sales charges received by JH Funds amounted to
$8,191.

         Class C shares which are redeemed within one year of purchase will be
subject to a CDSC at a rate of 1.00% of the lesser of the current market value
at the time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from the CDSC are paid to JH Funds and are used in whole or
in part to defray its expenses related to providing distribution related
services to the Fund in connection with the sale of Class C shares. For the

               John Hancock Funds - New York Tax-Free Income Fund


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

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

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

         Mr. Stephen L. Brown, Ms. Maureen R. Ford, Ms. Anne C. Hodsdon and Mr.
Richard S. Scipione are directors and/or officers of the Adviser and/or its
affiliates, as well as Trustees of the Fund. The compensation of unaffiliated
Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer, for
tax purposes, their receipt of this compensation under the John Hancock Group of
Funds Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation liability
are recorded on the Fund's books as an other asset. The deferred compensation
liability and the related other asset are always equal and are marked to market
on a periodic basis to reflect any income earned by the investment as well as
any unrealized gains or losses. The investment had no impact on the operations
of the Fund.
