Range DescriptionThis species is endemic to New Zealand. There have been no confirmed sightings of the species since 1967 when it was found on Big South Cape Island (near Stewart Island). It might still persist here or on other small privately-owned islands near Stewart Island.
It is known from subfossil remains on both North Island and South Island. By the time of European arrival, c.200 years ago, the species was probably already restricted to small islands off the coast of Stewart Island.
