New Zealand's former Covid-19 response minister will replace Jacinda Ardern as prime minister after receiving the only nomination from fellow MPs, the ruling Labour Party said on Saturday.

Iran PressAsia: New Zealand's Education Minister Chris Hipkins is set to become New Zealand’s next prime minister after he was the only candidate to enter the contest Saturday to replace Jacinda Ardern.

The 44-year-old senior politician must be formally backed by Labour members of parliament on Sunday before he takes over as the country's 41st prime minister, following Ardern's shock resignation on Thursday.

"It’s a big day for a boy from the Hutt,” Hipkins said, referring to the Hutt Valley near Wellington where he grew up. “I’m really humbled and really proud to be taking this on. It is the biggest responsibility and the biggest privilege of my life.”

Ardern shocked the nation of 5 million people on Thursday when she announced she was resigning after five-and-a-half years in the top role.

The lack of other candidates indicated party lawmakers had rallied behind Hipkins to avoid a drawn-out contest and any sign of disunity following Ardern’s departure. 219
