The stoat is a member of the mustelid family, along with weasels and ferrets. It was introduced to New Zealand in the 1880s to control rabbits and hares but is now a fierce predator of our native species. 


Rats

Rats have a major impact on New Zealand’s wildlife because they eat native animals and their eggs. They also eat a wide range of native fruit and plants, which puts them in competition with native wildlife for food.

 

Ship rats (Rattus rattus) do the most damage to our wildlife out of the three rat species found in New Zealand. They are good climbers, so they can access most bird nests high in trees. 

 

Norway rats (Rattus norvegicus) are large enough to kill nesting adult seabirds and prey on animals that live, roost or nest close to the ground.
