Niuatoputapu is located in the north of the Tonga island group, away from Vavau near the border with Samoa. Its closest neighbours are the small island of Tafahi, which is only to the north-northeast, and the island of Niuafo'ou. Those three islands together form the administrative division of the Niuas. Niuatoputapu Airport accepts international flights. An population was estimated at around 700 in 2020. Until several centuries ago, the inhabitants spoke the Niuatoputapu language, but it was replaced by the Tongan language and went extinct. Nevertheless, the variety of Tongan spoken on Niuatoputapu contains elements of Samoan, Uvean, and Futunan.
