coral atoll of Tokelau, a dependency of New Zealand in the South Pacific Ocean. It comprises 30 islets encircling a lagoon 8 miles (13 km) by 7 miles (11.3 km). Discovered (1791) and named Duke of Clarence Island by the captain of the British ship Pandora, which was searching for mutineers from HMS Bounty, Nukunonu's inhabitants were converted to Roman Catholicism (before 1858) by a Samoan missionary. The islanders depend upon coconuts, pandanus, and marine life for subsistence; fresh water is scarce. Shipping is hampered by the lack of an adequate anchorage. Local administration consists of a Taupulega (Council of Elders), made up of heads of family groups and two elected members. Area 1.8 square miles (4.7 square km). Pop. (2006) 287.
