Labour MP Mita Ririnui has announced he will stand down at the end of the year.
He was an associate minister in Helen Clark's government and former MP for Waiariki. Ririnui was born and raised in Tauranga and said his next role would be leading Bay of Plenty iwi through the Treaty settlement process.
"I also intend to be involved in the post-settlement challenges that iwi will be confronted with. These are exciting times," he said.
"I appreciate the experiences and opportunities I've had during my time here. I'm proud of my achievements and I wish my Labour colleagues all the best for the upcoming election."
Labour leader Phil Goff said he wished Ririnui all the best for his future.
"I'd like to acknowledge the contribution that Mita has made to the Labour caucus during his 12 years in Parliament, particularly the work he has done on behalf of the Maori community and the Ratana movement."
