Marama Fox 'stuck up for what she believed in' - Paula Bennett

There is optimism the Māori Party will survive, despite losing both its leaders.

Marama Fox has resigned as co-leader over private business issues, and Te Ururoa Flavell stood down earlier this year.

National deputy leader Paula Bennett says there are votes to be had.

"I think there's going to be a Māori vote that's going to be going. I hear from Māori that they're really disappointed, that they've really put a lot into Labour."

Ms Bennett says Ms Fox gave a lot to politics.

"She was feisty, she knew her own mind and she stuck up for what she believed in."

Greens co-leader James Shaw is unsure if the party will make a comeback.

"That's a decision for them to make. I think they made a valuable contribution in Parliament and I'd like to see them back, but ultimately that's up to them and it's a very hard journey."

Ms Fox has publicly apologised after her business was liquidated over unpaid debts.
