Jacinda Ardern to step down as New Zealand prime minister

New Zealand Prime Minister Jacinda Ardern made a shock announcement on Thursday that she had "no more in the tank" to continue leading the country - and would step down no later than early February without seeking re-election.

Ardern, holding back tears, said that it had been a tough five and a half years as prime minister and that she was only human and needed to step aside.

"This summer, I had hoped to find a way to prepare for not just another year, but another term - because that is what this year requires. I have not been able to do that," Ardern, 42, told a news conference.

"I know there will be much discussion in the aftermath of this decision as to what the so called 'real' reason was... The only interesting angle you will find is that after going on six years of some big challenges, that I am human," she continued. "Politicians are human. We give all that we can, for as long as we can, and then it's time. And for me, it’s time."

A ruling New Zealand Labour Party vote for a new leader will take place on Sunday; the party leader will be prime minister until the next general election. Ardern's term as leader will conclude no later than Feb. 7 and a general election will be held on Oct. 14.

Ardern said she believed Labour would win the upcoming election.

New Zealand Deputy Prime Minister Grant Robertson, who also serves as finance minister, said in a statement he would not seek to stand as the next Labour leader.

Ardern's successor as party leader and prime minister faces a stern test in a general election, with support for Labour falling and the country expected to go into a recession next quarter.

A 1News-Kantar poll released in December had Labour polling at 33%, down from 40% at the start of 2022. That means that even with traditional coalition partner the Green Party, polling at 9%, Labour could not hold a majority.
