Environmental groups are waging a new tech-war against pests on one of the country's most southern predator-free spots.
Ulva Island, just off the coast of Stewart Island/Rakiura was declared pest-free in 1996, but recent pest incursions have prompted conservation workers to up their game.
Hundreds of upgraded double-ended traps with cameras have been installed to find and hunt down, in particular, rats.
The 267 hectare island houses some of our most treasured birds and wildlife, including our national bird, the kiwi.
Protecting the island from predators has been heightened to keep the island safe or vulnerable animals.
"We've almost tripled the amount of traps and we've also installed a new network of cameras," said Department of Conservation (DOC) ranger, Kristen Clements.
