The show will run from 3pm to 9.30pm and organiser and manager of the Kaisen Charitable Trust David Trim said preparing an event of such a size was a huge task.
"We have to erect 1.3km of fencing, a massive stage, 36sq m outdoor screen, gateways and the full infrastructure of power, toilets and lights.
"Preparing an event of this size on a bare park takes months of planning and fundraising, and will involve about 200 volunteers.
"Christmas at the Park fully utilises the park with 20,000 people coming from all over Hawkes Bay to enjoy the atmosphere, surroundings and a great family night out", Mr Trim said.
In Hastings the annual Christmas in Cornwall Park will return this Sunday for the 129th time.
