The Green Party is due to announce who will replace Metiria Turei as its female co-leader.
Both contenders, Julie Anne Genter and Marama Davidson, will be at the announcement at 11am on Sunday in Auckland, along with co-leader James Shaw.
Last August Ms Turei stood down as co-leader following scrutiny of her public admission to committing benefit fraud in the early 1990s.
- 'I'll always be in politics' - Metiria Turei
- Newshub poll: Most Kiwis say Metiria Turei was wrong to lie to WINZ
Ms Genter told Newshub Nation the party had to paid a huge price in losing Ms Turei shortly before the election.
The 2017 election results were the worst for the party in more than a decade, but the Greens ended up with ministers for the first time in the Labour-led Government that was formed.
Going forward, the relationship the party has with the new leadership the National Party put in place after the election is likely to be an issue to watch.
- Greens' Julie Anne Genter intends to be a 'clearer, stronger' leader
- Greens leadership candidate Julie Anne Genter is pregnant
- Young Green members threaten to quit if Marama Davidson loses
Ms Davidson is reported to have campaigned for the co-leadership on her ability to criticise Labour more openly because she is not a minister but on the other hand Ms Genter has been impressing as a minister.
There are fears among some in the party that Ms Genter is too similar to Mr Shaw, and Ms Davidson would be a better complement - particularly in the youth wing.
