Conservation Minister Maggie Barry says she's stoked at how many households have joined the predator-free movement, but wants more.
Ms Barry says every New Zealand household should get involved in trapping, which can be done by contacting their local Department of Conservation office.
"They'll give them access to funding, access to expertise, and strategies that will help the community street by street, suburb by suburb, city by city achieve their goals so that by 2050 we can be free of rats, stoats and possums."
In the last year, more than 500 residents in Porirua have accessed traps, funded by a $300,000 grant.
The grant has gone to good use, Ms Barry said.
"Who knew a year ago that this would be the kind of thing that would really catch on with people? But when you see whole cities and suburbs joining in, it's incredibly encouraging."
Back yard trapping is a way any Kiwi can help to make New Zealand rat, possum and stoat free, she says.
