For sale: one hydro slide, well used, plus bumper boats and a mini-golf course in situ, Tahunanui Beach.

The Nelson City Council is calling for requests for proposal to buy the Nelson Fun Park in Tahunanui on council reserve, after the business owners Vivienne and Tom Mexted put the business on the market.

After close to 14 years of watching children and families have fun in the sun, they have decided to offer up the business.

"This will be our 14th season. We're both getting on and we've decided it's time to move on," Mrs Mexted said.

Mr Mexted said it was time someone with new ideas took on the business, which is privately owned but operated on council land.

"We've enjoyed our time here and it's a fun business to operate, but it's our time to move on," Mr Mexted said.

Throughout the time they had run the business people had shown interest in it, he said.

He declined to say what it was worth, saying that information would be provided to genuine prospective buyers through the formal process.

City council parks and facilities manager Paul McArthur said it would be up to the council to approve the lease for a new party taking on the business.

Use of the site on council reserve had to meet requirements of the Nelson Resource Management Plan.

The timing has coincided with an opportunity to take on the operation of Natureland.

Councillor Pete Rainey, who chairs the Natureland working group, said it was coincidental that the two opportunities had come up at the same time.

"We think there is a chance that some people might see the potential to suggest a combined or at least complementary use of both sites. But equally both operations can still be run independently."

The submissions process for each closes on October 8.

Staff and the Natureland working group will assess the expressions of interest received on Natureland before reporting back to council with a preferred option before Christmas.
