Population justification: No extant population remains.

Trend justification: The species apparently went extinct on Little Barrier Island during the 1870s after cats were introduced to the island (Tennyson and Martinson 2006). Another was reputedly shot on Browns Island/Motukorea in the Hauraki Gulf in the 1820s, and it was presumably extirpated from mainland North Island (where it is known from fossil records across the island) by Pacific rats in the prehistoric era (Tennyson and Martinson 2006).
