He told the council Pirimai had an increasing number of young families, who were among those already using the park for recreational activities. It could also engage youth, and help reduce anti-social behaviour.
If purchased, long-term fundraising ideas included a community garden, fitness trail, picnic area, and repairing its existing cricket pitch - a leftover from Pirimai school.
The request for council to add intent to purchase the park into the Long-term Plan 2018-2028 comes after 10 years of work from the PRA.
They said they had a "proven track record" of making the community's wishes a reality - having raised $31,000 after an unsuccessful 2008 appeal for the reserve to be extended, and playground equipment installed.
Another $34,000 was later fundraised for a junior playground. The council have since planted trees, installed a seat, barbecue table, and activity wall at the reserve.
The community support showed the "huge" demand for the park, and "as the existing playground has proven, build it and the people will come".
"After 10 years of lobbying, meetings, fundraising, petitions, and submissions we believe it is now time for council to put the wishes of the Pirimai community into action," he said.
Yesterday Napier Mayor Bill Dalton said the request would "go into the mix" to be considered in the LTP process.
