Wellington: As the only candidate nominated to lead the Labor Party, Chris Hipkins is expected to replace Jacinda Ardern as New Zealand's next prime minister, the party announced on Saturday. Hipkins is expected to be formally sworn in as the party's new leader on Sunday at a meeting of the Labor Party's 64 MPs, or caucus. Ardern unexpectedly announced on Thursday that she would resign as Prime Minister of New Zealand and not seek re-election because she had "no more in the tank" to do so.

Hipkins currently serves as both Leader of the House and Minister of Police, Education and Public Services. According to a Horizon Research Quick Poll obtained Friday by local media outlet Stuff, Hipkins was the most preferred potential candidate among voters, supported by 26% of those polled.

Prior to Hipkins' appointment, Ardern will submit her letter of resignation to the Canadian prime minister. His first press conference is scheduled for Saturday afternoon. Hipkins will serve as leader until the party's mandate is confirmed. There will be a general election on 14 October and according to some polls it will be difficult for the Labor Party to retain power. According to a Taxpayers Union-Curia poll using data released on the Friday after Ardern announced she would step down, support for Labor had fallen to 31.7%, while support for the opposition New Zealand National Party stood at 37.2%.
