Motunau Island is a small, 3 ha (7.4 acres), island nature reserve lying 1.2 km (0.75 mi) off the coast of New Zealand’s South Island, at the northern end of Pegasus Bay, south of the mouth of the Motunau River. The reserve is managed by the Department of Conservation and access is by permit only.
About 300 m (980 ft) long by 100 m (330 ft) wide, the island has steep sides rising to a distinctive flat top some 25 m (82 ft) above sea level. Geologically, it consists of Tertiary rocks, capped with loess and gravels, and surrounded by eroding cliffs and wave-cut reefs. The soils are extensively burrowed by nesting seabirds.
The island is an important site for seabirds. In 1967, it was the breeding site of an estimated 23,000 individual birds. It is home to a colony of 5,000 white-flippered penguins. Other birds recorded as breeding there include white-faced storm petrels, sooty shearwaters, fairy prions, variable oystercatchers and white-fronted terns. The island has the only colony of white-faced storm petrels found along the coast between Cook Strait and the Otago Peninsula.
Three species of lizard inhabit the island, including the species Leiolopsima lineocellatum, which is considered regionally uncommon.
