Mr Jack said apart from the economic benefits of big events, there were also big gains in social development.
Hawke's Bay is also set to stage the international between the All Blacks and Argentina on September 6. Only about 2,300 tickets remain available for the test, with more than 20,000 sold.
The Hawke's Bay Rugby Union's commercial manager, Jay Campbell, believes that once people see how fantastic the view is from the new seating, the last tickets will be snapped up.
Additional seating of 9,500 is being built on the embankment especially for the All Blacks' match, which will take the ground's capacity to just over 22,500.
