"I personally wanted to give back to this area that had given so much to me," he said.
Support was gained from the Kaipara District Council's and Joe Moores, who does specialised work on some of the council's playgrounds.
Mr Moores said he became involved because he felt the domain deserved better than the outdated swings, but recognised the council probably had higher playground priorities elsewhere.
Domain Ranger Dave Bolland and Camp Manager Andrew Howells built the safety surface surrounds and installed the cushion-fall safety surfacing.
"This will give children something to do away from the water or when conditions don't suit swimming," Mr Howells said. "I think it will prove very popular."
