Sikaiana (formerly called the Stewart Islands) is a small atoll 212 kilometres (132 miles) NE of Malaita in Solomon Islands in the south Pacific Ocean. It is almost 14 kilometres (8.7 miles) in length and its lagoon, known as Te Moana, is totally enclosed by the coral reef. There is no safe anchorage close to this atoll, which makes it often inaccessible to outsiders. Sikaiana's population is approximately 300 people of Polynesian descent—not of the Melanesian descent prevalent in the main Solomon Islands. It is considered by anthropologists to be a Polynesian outlier.
