Jacinda Ardern resigns as prime minister of New Zealand | Jacinda Ardern

New Zealand prime minister Jacinda Ardern has announced her resignation in a shock announcement.

At the party’s annual caucus meeting on Thursday, Ardern said she “no longer had enough in the tank” to do the job. “It’s time,” she said.

“I’m leaving, because with such a privileged role comes responsibility. The responsibility to know when you are the right person to lead and also when you are not. I know what this job takes. And I know that I no longer have enough in the tank to do it justice. It’s that simple,” she said.

Her term as prime minister will conclude no later than 7 February.

“I am human, 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,” she said. Ardern said she had reflected over the summer break on whether she had the energy to continue in the role, and had concluded she did not.

Ardern became the world’s youngest female head of government when she was elected prime minister in 2017 at age 37. She has led New Zealand through the Covid-19 pandemic, and major disasters including the terror attack on two mosques in Christchurch, and the White Island volcanic eruption.

Asked how she would like New Zealanders to remember her leadership, she said “as someone who always tried to be kind.”

“I hope I leave New Zealanders with a belief that you can be kind, but strong, empathetic but decisive, optimistic but focused. And that you can be your own kind of leader – one who knows when it’s time to go,” Ardern said.
