Waiariki is a New Zealand parliamentary Māori electorate that was established for the 1999 election, replacing the Te Tai Rawhiti electorate. It is currently held by Māori Party co-leader Rawiri Waititi, who won it in the 2020 general election. Waiariki was an important electorate in the 2020 election as Waititi's win allowed the Māori Party to re-enter parliament with two MPs, despite not reaching the 5% party vote threshold needed for parties without an electorate seat.
