"Waitangi Day is our biggest event and the Te Matatini kapa haka festival, which takes place in February 2017, is expected to attract around 30,000 spectators, so it will be huge," Mr Mackintosh said.
He said the growth was a result of supplying first class facilities and good management of the sporting codes.
"The Unison Hockey Stadium is world class and certainly the best in New Zealand so it's not surprising that we are getting increasing numbers there.
"Meanwhile, HB Netball has been voted best regional sports organisation for the past two years at the Hawke's Bay Sports Awards, so they are clearly doing a good job."
Mr Mackintosh said increasing numbers had created the "good problem" of congestion, but this was being addressed as funding allowed. Last month, Hastings District Council completed the extension of Percival Rd, creating a second entry and exit to the park, which had improved traffic flow.
Plans are under way for a new netball building, expected to open for the 2016 winter season.
