National Party MP and Cabinet minister Georgina te Heuheu is to retire from politics at the end of the term.
Mrs te Heuheu entered Parliament in 1996 and holds portfolios including Courts and Pacific Island Affairs.
She was the first female Maori MP for the National Party.
In 2004, she was replaced as the party's Maori Affairs spokesperson, after refusing to endorse then leader Don Brash's race relations Orewa speech.
Mrs te Heuheu says now is the right time to go, as National is in good heart.
However, she says politics has been a brutal game.
