For Immediate Release
April 3, 2005

                          CANWEST MEDIAWORKS NZ REPORTS
                12% EBITDA INCREASE FOR FIRST HALF OF FISCAL 2005

           First interim dividend of $0.04 per share to be paid in May

Winnipeg - CanWest Global Communications Corp. announced today that its
70%-owned New Zealand media operation, CanWest MediaWorks (NZ) Limited, reported
consolidated earnings before interest, income tax, depreciation and amortization
(EBITDA) of NZ$37.9 million for the six months ended February 28, 2005, a 12%
improvement compared with pro forma results for the same period last year. The
Company's consolidated revenues increased by 8% to NZ$124.6 million compared to
pro forma revenue of NZ$115.0 million in the same period last year. These
results are recorded in accordance with New Zealand GAAP and will be subject to
adjustment to Canadian GAAP upon consolidation with CanWest Global
Communications Corp.'s other media operations

CanWest MediaWorks (NZ) is a publicly-traded company listed on the New Zealand
Stock Exchange. The Company was reorganized for its public share offering in
July 2004. Pro forma financial results for the prior year reflect the combined
results of CanWest TVWorks Limited and CanWest RadioWorks Limited, which are
comparable to the current year's consolidated financial results.

The Company's Directors have approved an interim dividend of NZ$0.04 per share
to be paid for the six month period ended February 28, 2005. The dividend will
be paid on May 16, to shareholders of record as of May 6, 2005, and will carry
full imputation credits. CanWest Global expects to receive aggregate dividends
of approximately NZ$6.3 million in May 2005.

"We are extremely well satisfied with the financial performance of the Company.
Our radio and television brands are all performing very well," said Tom Strike,
Chairman of CanWest MediaWorks (NZ) and President of CanWest MediaWorks
International.

Brent Impey, CanWest MediaWorks (NZ)'s Chief Executive Officer, pointed to the
exceptional results of TVWorks, which experienced an impressive 27% increase in
EBITDA for the first half of the fiscal year, compared to results for the same
period last year. "A NZ$3.6 million increase in EBITDA for TVWorks to NZ$20.2
million confirms the strength of the television operations."

The Company's radio operations, known as RadioWorks, also recorded significant
EBITDA gain, with a 7% increase to NZ$19.0 million for the six months ended
February 28, compared with EBITDA of NZ$17.8 million for the same period of the
previous year.

RadioWorks completed a number of strategic initiatives during the first half of
the year which included the strengthening the national brand profile of More FM
by re-branding 15 local stations under the More FM banner; the launch of Kiwi
FM, which plays 100% New Zealand music, into Auckland, Wellington and
Christchurch; the re-branding of several more stations under the easy listening
The Breeze format; the acquisition of additional frequencies in the North Island
and the upcoming launch next week of the Radio Live network, which will take a
more contemporary approach to news and talk radio.

TVWorks also launch significant new programming with a re-launch of the news
flagship 3 News with new anchors, and the launch of Campbell Live, a
high-profile weeknight current affairs program that won its time slot out of the
gate.
