Ship Rat

Rattus rattus is an introduced climbing rat widespread in New Zealand forests. It differs from the Norway rat through its slimmer build, larger ears and tail longer than the head and body. The coat varies from black to brown-grey, and the muzzle is pointed. Its long tail and agile climbing are useful clues.

It occupies forests, scrub, farms and buildings across the main islands. Intensive control suppresses it at sanctuaries such as Zealandia and Pureora Forest sites. It eats fruit, seeds, insects, eggs and small vertebrates. It is nocturnal and frequently forages in trees.

New Zealand treats it as Introduced. There is no ethical viewing site; tracking tunnels and control stations are visible at Zealandia in Wellington.
