The park is home to several unique invertebrate species, and almost half of New Zealand’s indigenous fish species are found in or near the park.

Nationally threatened fish species include the giant kokopu, short-jawed kokopu, banded kokopu and koaro.

Powelliphanta land snails are among the largest snails in the world, growing up to 90mm across with colourful yellow, brown and black patterned shells. They are carnivorous, sucking up earthworms like spaghetti but are one of our most threatened invertebrates as they are very vulnerable to possums, rats, pigs, hedgehogs and thrushes.

Long and short-tailed bats are critically endangered in New Zealand. Over the years there has been a number of suspected sightings of these bats on our Mounga, but these have been unconfirmed. In 2019, the project recently conducted monitoring to detect the presence of short-tailed bats around the Park. Our rangers have completed analysing the audio files and concluded no bats were recorded. The team will continue our searching efforts across the Park in the coming summers. This work will in turn help the bat-pollinated rare parasitic plant Dactylanthus.
