The island country of Niue lies in the South Pacific Ocean, between Cook Islands, Samoa, and Tonga. Covering 261 square kilometers, it's among the biggest coral islands in the world and is surrounded by a coral reef. Niue is the Cook Islands' westernmost island, but it is an administratively separate jurisdiction.
Instead, it's a self-governing island state in a formal, free relationship or association with New Zealand. In fact, New Zealand conducts diplomatic activities and relations on Niue's behalf. The island's estimated population in 2018 was 1,620, with many living in the capital of Alofi. Niue uses the New Zealand dollar as its currency and tourism is among its major industries.
