On Friday, the race to replace Metiria Turei as Green Party co-leader will begin.
It's been seven months since Ms Turei resigned and James Shaw has steered the ship alone, but the party's constitution dictates that he must have a female counterpart.
But it's not a simple process.
The tree hugger who's Conservation Minister, the fierce public transport advocate who owns six bikes and the social activist: they are the main contenders to be the Green Party's new co-leader.
Julie Anne Genter, 38
Minister for Women and Associate Minister for Health and Transport
She's a huge fan of Netflix series Stranger Things.
Marama Davidson, 44
Spokeswoman for Māori affairs and Housing
She was arrested in Israel while on a peace flotilla.
Eugenie Sage, 48
She spent 13 years campaigning for Forest & Bird.
The Green Party's passionate about things it cares about and feisty too, when it was too soon to ask that question about the co-leadership.
"It is way too early to ask that question," Ms Genter told Newshub in 2017. "I said it's too early, don't even think about asking me that until after the election."
Because of the party's rules around the election process, none of the possible candidates would confirm to Newshub that they'd run.
They will be able to talk about it from tomorrow, when nominations open.
They close on February 9, candidates are announced three days later.
Party delegates cast votes on behalf of their electorates between March 26 and April 7.
The winner will be announced on April 8.
An outsider in the race is long-time sexual violence campaigner Jan Logie.
Chloe Swarbrick won't enter the race, nor will New Zealand's first refugee MP, Golriz Ghahraman.
Marama Davidson is set to announce she's in the running this Sunday at an event in Mangere.
In the latest Newshub-Reid Research poll, the party was at 6 percent.
It's vital the party gets the leadership right - if they get it wrong, their political survival will be at risk.
