Twenty-year-old Jack Tautokai McDonald has been selected as the Green Party's candidate for Te Tai Hauauru.
And the Greens are talking of a "generational shift" in the electorate, with the retirement of encumbent Tariana Turia.
Mr McDonald, who is of Taranaki iwi, Te Whakatohea and Te Ati Awa descent, also contested the seat in 2011 for the Greens, after just turning 18.
He placed third, increasing the Greens' party vote in the electorate from 3.4 per cent to 10.9 per cent.
"It is an honour to have been re-selected as the Green Party candidate for Te Tai Hauauru and to have the opportunity to run a strong campaign to increase our party vote in Te Tai Hauauru and across Maori communities," said Mr McDonald.
