Hannah Tamaki has announced she will be contesting the Māori electorate seat of Waiariki seat in this year's election.
She is standing for the party which she leads, Vision New Zealand, set up last year.
Waiariki was held by former Māori Party co-leader Te Ururoa Flavell until he was beaten at the 2017 election by Labour's Tamati Coffey, by a margin of 1719 votes.
This year's Māori Party candidate for the seat is Rawiri Waititi.
Tamaki said she is determined to work with others in Wairiki to end homelessness, child uplifts, broken homes and inequality.
"Labour has had its turn, the Māori Party has had its turn, now it's my turn. There is a new breed of politician on the rise, one who keeps their promises and who leads a party with totally new and innovative solutions for Māori," she said.
Vision New Zealand party secretary Anne Williamson said it makes sense for Tamaki to stand in the area that she has whakapapa. She has invested many years in the area and has a strong connection to it, Williamson added.
