The Predators

The proposal is to remove rats, possums, feral cats and hedgehogs from the mainland and islands of Rakiura/Stewart Island, as these predators eat or compete with wildlife and vegetation.

By removing these priority predators, we believe Rakiura will benefit.

Deer and domestic pet cats are not in scope for removal.

Stoats, weasels, ferrets, pigs and goats are not present on Rakiura. Mice arrive on Rakiura with no established population known.
