Turia to stand down in 2014
Maori Party founder Tariana Turia will stand down at the next election.
She announced her decision on Friday, saying she wanted to give the party plenty of time to consider a replacement for the co-leadership position she has held since 2004.
"I have given it serious thought and have made the decision with my family not to seek re-election in 2014," she said.
"I am looking forward to spending more time with my husband and our mokopuna."
Mrs Turia's decision will be a blow to the party because she is its only MP with a safe seat in parliament.
Her co-leader, Pita Sharples, says he and Mrs Turia have steered the waka for the last eight years.
"It will be a huge change to lose my mate," he said.
"I totally support her decision, she will be leaving a legacy of opportunity for Maori."
The party's third MP, Te Ururoa Flavell, is almost certain to succeed Mrs Turia as co-leader.
He says she has shown inspiring leadership and absolute commitment.
Mrs Turia came to parliament as a Labour MP but quit the party over the Foreshore and Seabed Act and formed the Maori Party.
It has three MPs in parliament and has signed a support agreement with National.
