New Zealand chooses Chris Hipkins to replace Ardern

Hipkins, 44, was the only nomination for the job and his confirmation at a party meeting on Sunday, known as the Labour caucus, was largely a formality.

His appointment to the top job followed the surprise resignation on Thursday by Ardern, who said she had "no more in the tank" to lead the country.

"This is the biggest privilege and biggest responsibility of my life," Hipkins said at a news conference announcing his appointment. "I am energised and excited by the challenge that lies ahead."

Hipkins immediately acknowledged the leadership of Ardern, who he called one of New Zealand’s greatest prime ministers and an inspiration to women and girls everywhere.

"She gave voice to those often overlooked in times of challenge and purposefully went about doing politics differently," Hipkins said.
