Biosecurity

Tiritiri Matangi is free of mammalian predators and it is very important to keep it that way. Many of the species that live on Tiritiri Matangi are vulnerable to predation by rats, mice, stoats or weasels. A single pregnant rat could devastate a bird or reptile population. Cats and dogs are also a threat, particularly to ground-nesting birds like kiwi. Pets are not permitted on Tiritiri Matangi even on a leash. A bag that is packed the night before, especially if it contains food, could harbour a rat or mouse, so please check your bag before you leave home.

Tiritiri has implemented a weed management programme to ensure that important native plants are not overwhelmed by rampant species such as boxthorn, moth plant or Japanese honeysuckle. Before you come to Tiritiri please check your shoes, boots, pack and clothing for weed seeds and clean them thoroughly if necessary.
