Jacinda Ardern has turned to feminist icon and former Australian Prime Minister Julia Gillard to help fundraise for the New Zealand Labour party.
Ms Ardern will host an online conversation with Ms Gillard on Wednesday night, when the pair will discuss "global issues, gender in politics, and reflect on their careers to date", according to the advertisement.
Earlier this month, Ms Gillard hosted events in Melbourne and Sydney to recognise the 10th anniversary of her misogyny speech to parliament.
Ms Ardern sent a video message that was replayed on stage at those events, revealing she fist-pumped in 2012, then an opposition MP, when she first saw the speech.
"It was time after time that she and other women in politics were having to put up with blatant sexism and underhand marks and particular portrayals," Ms Ardern said.
"You knew what was sitting behind it and it was just so corrosive.
"They just kept happening time and time again until that moment where she stood up in parliament and said: enough."
The Kiwi leader likened Ms Gillard's treatment to a character from a movie from her childhood.
"When I watched (the misogyny speech) I was thinking back to when I was a kid and watching the film Back to the Future," she said.
"You see George McFly just being bullied and harassed for that entire film until he says: enough. That's how it felt to me. And we were all fist-pumping."
Ms Ardern said she had a couple of interactions with Ms Gillard over the years and the pair enjoyed a friendly relationship.
Speaking in Wellington on Monday, Ms Ardern said she imagined it would be easier to be a female politician on her side of the Tasman.
"I do think the New Zealand environment is a bit different to the Australian one," she said.
"I have not recalled during the time that I've campaigned that it's been particularly remarked upon domestically that I'm a woman.
"It doesn't mean it's been plain sailing but I don't think it's nearly as pronounced as it otherwise might have been.
"I've had the benefit of coming in on a path that's already been carved by other female politicians and prime ministers.
"They've spent time in office removing or at least taking on some of those challenges around being a first, and some of the challenges that may come with being a female in leadership."
Ms Ardern said she had never been moved to give a similar impassioned address as she had not experienced similar treatment "in such a blatant way in parliament itself".
Labour's Zoom fundraiser, which also offers Kiwis the chance to ask questions of the pair, will cost $NZ40 ($A35.84).
Ms Gillard's office did not respond to a request for comment.
