Ngatangiia is a Cook Islands electoral division returning one member to the Cook Islands Parliament.
The electorate was created in 1981, when the Constitution Amendment (No. 9) Act 1980–1981[1] adjusted electorate boundaries and split the electorate of Takitumu into three. It consists of the tapere of Turangi, Ngati Au, Ngati Maoate, Ngati Vaikai, Avana, Aroko, Nukupure (Muri), Areiti, Aremango, Vaii, and Maii on the island of Rarotonga.
