In the late 1800s, Governor Grey introduced this and four other species of wallabies (including the rare parma wallaby) to islands in Hauraki Gulf, near Auckland, New Zealand, where they became well-established. In modern times, the wallabies have come to be viewed as exotic pests. They have caused problems for the native plants and animals and are being removed from the islands. Between 1967 and 1975, 210 rock-wallabies were captured on Kawau Island and returned to Australia, along with thousands of other wallabies. Rock-wallabies were removed from Rangitoto and Motutapu Islands during the 1990s. Another 33 rock-wallabies were captured on Kawau during the 2000s, and returned to Australia.
