Gareth Morgan wants Karori residents to lead the charge in establishing a predator-free New Zealand.
Mr Morgan is holding a public meeting in Allen Ward Hall, Donald St, on Wednesday next week at 7pm to challenge Karori to become the first "confined cat-only" suburb.
"This is not just about conservation and saving native species," Morgan said. "It is about cashing in on our natural capital, making New Zealand a unique, world-class place to visit and live in.
"We can start right here in Karori - Zealandia has already done the hard work, now the rest of us need to step up."
He said cats need to be managed like dogs, with registration and micro-chipping, and stray and feral cats should be euthanised.
Mr Morgan commissioned a survey. He said 80 per cent disagreed with the SPCA's policy of releasing stray cats and 65 per cent believed cats should be registered.
About 40 per cent agreed to make their current cat the last.
