Mr Filleul said the council has been good to work with: "They haven't taken the stance of closing the whole place after one accident."
The incident had been the only blip at a playground Henderson-Massey local board chairwoman Vanessa Neeson described as "a huge success".
Ms Neeson said children, including her own grandchildren, enjoyed the thrills the park offered - it also boasted flying foxes and a climbing tower with rope "nests".
"It's about taking risks, which helps kids grow in confidence and self-esteem."
Mr Filleul said in the past children played on high ropes and climbed trees. "I encourage that behaviour, but in a safe environment," he said.
Playground Centre is a family operated business that moved from Auckland to Wanganui. It has 22 staff and 75 per cent of its equipment is manufactured in Wanganui and the Manawatu area.
The company has built play areas in schools around Wanganui and in Carlton Park, and recently revamped the playground at Kai Iwi beach.
However, Mr Filleul wouldn't change a thing about Wanganui's popular Kowhai Park - his kids love it.
"If something's working, what are you trying to do? Spending a lot of money and putting in the wrong equipment defeats the purpose," he said.
