Ebbett Park residents have started a petition to stop the potential sale of part of the park.
Hastings District Council's draft Raureka Parks Reserves Management plan has a clause allowing the north west end of Ebbett Park to be sold, to allow for flexibility in the future.
The rest of Ebbett Park would be declared a reserve under the Reserves Management Act 1977.
Residents Bernice Koenders, Wayne Taylor, Alistair Chalmers and Jean Chalmers have started a petition to see the entire park protected under the Reserves Management Act 1977, protecting it from possible future sale.
The group said the park was gifted to Hastings as a reserve, according to the original deed of trust.
