Peeni Henare plans to follow his great-grandfather Taurekareka Henare (1878-1940) into Parliament.
Mr Henare was selected at the weekend as the Labour candidate for Tamaki Makaurau, now held by Maori Party co-leader and Minister of Maori Affairs Pita Sharples, who will not seek re-election in September.
Mr Henare is Labour's second choice for the candidacy.
He was selected after broadcaster Shane Taurima's nomination was blocked following an investigation into misuse of TVNZ resources for political purposes.
Mr Henare, 34, is the son of Maori Language Commissioner Erima Henare, and grandson of the late Sir James Henare, who rose from the rank of private to commanding officer of the Maori Battalion during World War II.
