'No plans to change what I'm doing': Jacinda Ardern on whether she'll run at election 2023

Jacinda Ardern says she's focusing on the here and now amid questions about whether she'll run for re-election in 2023.

The Prime Minister's Labour party is voting on potential new rules on replacing a leader this weekend. Instead of putting it to the party membership and affiliated unions, it would go to a simple caucus vote.

In an interview with TVNZ's Q+A on Sunday, Ardern was asked if she would commit to running for reelection in 2023 - what would be her third term as Prime Minister.

"Oh… I'm only one year into the one I'm now," Ardern told Q+A.

"I have no plans to change what I am doing and so that is, I am the leader of the Labour party, I am currently privileged to be the Prime Minister of New Zealand.

"I have no other plans for my future than what I am doing right now."

She made similar comments during a lengthy interview with Newshub political editor Tova O'Brien which aired on Saturday.

"Regardless of the fact that you can't anticipate what you will come up against in this job, I still consider this to be the greatest privilege of my life," she told Newshub Nation host O'Brien.

"I'm not stopping. I need to carry us through. It's my job." 

In the latest Newshub-Reid Research poll, carried out in August Ardern, despite losing 2.6 points, sat at 45.5 percent as preferred Prime Minister - well ahead of ACT's David Seymour (8.6 percent) and National's Judith Collins (8.2).
