Wellington predator-free communities have snagged more than 5000 rats since introducing backyard trapping.
Next Predator Free Community spokesperson and "urban predator hunter" Kelvin Hastie says his suburb of Crofton Downs is seeing an explosion of native wildlife.
"Now we've got a population of kākā. We're starting to see them hanging around in winter. We've also seen some rare lizards in our community."
He told Newshub it's just a matter of getting someone on board in the community to lead it.
"It's all part of seeing birds back in our neighbourhood. It's pretty simple. It's one in five people trapping in their backyards in their community."
Rat and possum traps can now be found in 26 Wellington suburbs.
A fund of $300,000 has been set aside to help the Department of Conservation set up suburban traps.
