Jacinda Ardern set for a $1million payday with book publisher Penguin Random ... trends now

Former New Zealand Prime Minister Jacinda Ardern could receive more than $1million in a record-breaking advance for her rumoured biography.

Ms Ardern, 42, is believed to be close to signing a book deal with publishing house Penguin after a major bidding war with several international publishers.

Her first authorised biography is set to be Ms Ardern's first major career move since resigning from office in April. 

It's understood the advance for Ms Ardern's book could fetch anywhere between $1million and $1.5million, the NZ Herald reported on Friday.

Most publishing advances for Kiwi authors sit between $5,000 and $10,000. A typical memoir for a famous politician could go for as much as $20,000. 

Penguin remains tight-lipped on the supposed deal and any of the book details. 

'I don't think I can talk about that. Who's suggested that you get in touch with me about this?,' Penguin Random House New Zealand head of publishing Claire Murdoch said.

'I'm not in a position to comment on this. I don't think I can say anything about it. Presumably, there's one very obvious person to talk to about this.' 

Ms Ardern is currently in the US.

Her EA told the Herald she couldn't comment. 

Time Out Bookstore Manager Jenna Todd told Newstalk ZB radio host Heather Du Plessis-Allan on Friday that there'll be a lot of talk about the book and it'll sell on its own.

She added the book would have lots of international appeal.

Former All Blacks rugby star Sonny Bill Williams' autobiography payday came close to Ms Ardern's rumoured amount when the New Zealand, Australian and UK book rights were sold for $1million in 2021.

It's understood a publisher would need to sell at least 100,000 copies of a book to breakeven on a $1million deal.

While Ms Ardern has already been the subject of several biographies, including a children's story, her new book will be the first authorised one.
