Community leaders are defending their decision to give extra funding to a world record attempt to create the biggest ice-cream sundae.

Manurewa Local Board members acknowledged at last week's public meeting that there had been some criticism about the cost of the event.

In October last year it approved $10,000 for the challenge and an extra $7000 has now been allocated.

But chairwoman Angela Dalton said it's going to be a "major event" that's expected to attract thousands of people.

The board has been given a "clear directive" from people in the community for more family activities, she said.

"People say 'we want more of this' . . . certainly through our consultation that's what the community are saying.

"I encourage people who have something to say, if they don't want money spent on these events, to submit what they want it spent on so I can get a direction."

Dalton said there are extra costs such as filming for authenticating the official world record attempt. Other significant costs include table and chair hire as well as health and safety measures.

Tip-Top is one of the sponsors and will be covering the cost of all the ice-cream.

The challenge begins at 4pm on February 28 at Sykes Rd Park, after the Manurewa Community Fun Day which kicks off at 10am.
