Tengatangi–Areora–Ngatiarua is a Cook Islands electoral division returning one member to the Cook Islands Parliament. Its current representative is the Hon Te Hani Brown, who has held the seat since 2018.
The electorate was created in 1981, when the Constitution Amendment (No. 9) Act 1980 adjusted electorate boundaries and split the multimember electorate of Atiu into two separate constituencies.[1]
Unless otherwise stated, all MPs terms began and ended at general elections.
