Located in Oceania, Tonga is a small archipelago in the South Pacific Ocean, directly south of Samoa and about two-thirds of the way from Hawaii to New Zealand. It has 169 islands, 36 of them inhabited, which are in three main groups – Vavaʻu, Haʻapai, and Tongatapu – and cover an 800-kilometre (500-mile)-long north–south line. The total size is just 747 km2 (288 sq mi). Due to the spread out islands it has the 40th largest Exclusive Economic Zone of 659,558 km2 (254,657 sq mi).

Vavaʻu is an island group, consisting of one large island and 40 smaller ones, in Tonga. It is part of Vavaʻu District, which includes several other individual islands. According to tradition, the Maui god created both Tongatapu and Vavaʻu, but put a little more effort into the former. Vavaʻu rises 204 m (669 ft) above sea level at Mount Talau. The capital is Neiafu, situated at the Port of Refuge.
