Deer (Cervus elaphus) were introduced
into the park from Canada, and have no natural predators.
Deer live in a variety of habitats and initiate harmful changes in plant communities foraging selectively.
Deer cause damage to native forests by feeding on forest plants, trees and seedlings.

Ferrets (Mustela putorius) were introduced to New Zealand from Europe in the 1880s, along with stoats and weasels to control rabbits.
In 1900, ferrets were well established in nature and undoubtedly played a role in the decline of native birds like the kiwi, weka and blue duck, and the extinction of kakapo on the continent.
Nowadays Kakapo is only found in free-mustelids areas.
Stoats (Mustela erminea) are now considered "public enemy
number one" for the Birds of New Zealand.
They were introduced to New Zealand in the 1880s to control rabbits and hares.
Stoats are involved in the extinction of some native bird species (bush wren, laughing owl and native thrush) and as the main cause of the decline of many others (SI Kōkako, takahe, kaka, Mohua, Hutton Shearwater, kakapo, Kakariki, the Okarito kiwi kiwi and other species).

Weasels (Mustela nivalis) are found in low
numbers in most habitat types in New Zealand but with big impact on lizard and
invertebrate populations as well as bird life.
Weasels will tackle a prey much larger than themselves and nesting birds are easy targets for them.
They were introduced to New Zealand in the 1870s

Hedgehog (Erinaceus europaeus) have voracious appetites.
They are a threat to native weta, skinks, and the eggs and chicks of ground-nesting birds.
Possums (Didelphis marsupialis) compete with native birds for habitat and food such as insects and berries. They also disturb nesting birds. They eat their eggs and chicks.
They were introduced to New Zealand in 1837 to establish a fur trade.
Rainbow parrot (Trichoglossus haematodus) was illegally released in
the 1990s.
They are native from some parts of Australia.
Evidence shows that rainbow parrot compete with native birds by dominating their food sources and nesting sites.
They are capable of dislodging much larger birds than themselves.
They may also carry avian diseases which can threat the health of native bird species.
