Mou Waho is a 120-hectare island in Lake Wānaka, New Zealand. It is around the same size as the nearby Mou Tapu, these two islands being the largest in the lake. The island contains a small recursive lake, called Arethusa Pool: a glacial-scoured lake formed by the most recent ice age on an island, in a lake on an island.
Buff weka thrive on the island are predators of much of the native wildlife including mountain stone wētā, cave wētā, and Southern Alps geckos. For this reason students of the local Mount Aspiring College built 40 small wooden motels for these animals to safely live in.
