Manihiki Island is not a city, but rather an island in the Cook Islands, which is a self-governing territory in free association with New Zealand. The island is located in the central Pacific Ocean and is part of the Northern Group of the Cook Islands. The main settlement on Manihiki Island is Tauhunu, which is the main village and administrative center of the island. While it is not a city in the traditional sense, it is an important hub for the local community and the center for economic activities such as pearl farming and tourism.
