Atafu

Atafu, formerly known as the Duke of York Group, is a group of 52 coral islets within Tokelau in the south Pacific Ocean, 500 kilometres (310 miles) north of Samoa. With a land area of 2.5 square kilometres (1.0 square mile), it is the smallest of the three islands that constitute Tokelau. It is an atoll and surrounds a central lagoon, which covers some 15 km² (5.8 sq mi). The atoll lies 800 kilometres (500 miles) south of the equator at 8° 35' South, 172° 30' West. Atafu is the northernmost area under New Zealand sovereignty.
