Metiria Turei will stay on as Green Party co-leader at least until the election.
There's been speculation over Ms Turei's co-leadership after she admitted to benefit and electoral fraud.
Speaking to media today Ms Turei says she will stay on as co-leader until at least the election, on September 23.
"I'm committed to staying on at least until the election, because we have a really important job to do.
"I know I have the support of my party and I know I have the support of my caucus so I will continue until election day," Ms Turei said.
Yesterday Green MPs Kennedy Graham and David Clendon withdrew from being candidates last night over dissatisfaction with Ms Turei.
Today they have quit the Green Party caucus.
"David and Kennedy withdrew from caucus today. That decision was supported by the other 12 Green Party MPs," said Green Party co-leader James Shaw said in a statement today.
"They have made the right decision today. We wish David and Kennedy the best.
"The remainder of the Green Party caucus is 100 percent behind our co-leader, Metiria."
