Many of the islands of the Gulf are pest free, or partially pest free. This means they are now home to some of New Zealand’s rarest and most endangered species – eg tuatara, takahe, shore plover and kiwi. The islands are also recovering naturally as birds reintroduce themselves to these safe havens. It is important to keep them pest free – and we need your help! Pest animals and plants can invade our islands by stowing away on or in your footwear, gear or boat. Rats can squeeze through a 12 mm gap and mice can squeeze through a 7 mm gap. Insects could hide in your bag, and weeds, seeds and soil could cling to your clothing and shoes. Pests threaten New Zealand’s native wildlife.
