Albanese first to welcome NZ PM Hipkins

Chris Hipkins says he will conduct in-person talks with Australia's Anthony Albanese soon after his swearing in as New Zealand prime minister.

Mr Hipkins emerged as the consensus candidate to follow Jacinda Ardern as Labour leader, and he will soon be ratified as prime minister.

Mr Albanese wasted no time in beginning trans-Tasman dialogue.

"A warm discussion this morning with incoming NZ Labour Leader Chris Hipkins. I congratulate him and look forward to working with him as prime minister," Mr Albanese tweeted on Saturday.

Speaking outside Wellington's parliament house, Mr Hipkins said he missed Mr Albanese's call but quickly returned it.

"It's been great to be able to talk to him. I'm looking forward to catching up with him. I hope in-person fairly soon," he said.

"That clearly is a very important relationship for New Zealand.

"He's had a very solid working relationship with Jacinda Ardern. From our conversation this morning, which was very warm, I'm absolutely sure that we're going to have a very good working relationship as well."

Mr Hipkins will have nine months in the top job before he faces voters, leading Labour into a general election on October 14.

Opposition leader Chris Luxon congratulated Mr Hipkins, in the next breath resumed his party's attacks on Labour.

"It's a tremendous privilege and a great honour to be able to lead any political party and to be prime minister," he said.

"From my perspective, though, just changing the leadership of the Labour party doesn't do enough for the New Zealand people.

"Chris Hipkins has been part of a Labour government that has spectacularly failed to get anything done."

Mr Hipkins' Labour colleagues were more complimentary, with Deputy Prime Minister Grant Robertson - who was best man at his wedding - congratulating the 44-year-old.

"My mate Chippy has been there through thick and thin. He is experienced and deeply grounded in Labour values," Mr Robertson wrote on Facebook.

"He is going to be a great Leader and PM. Still a bit of our process to go, but very proud of our Labour team."

The Greens, who hold two ministries in the current government, also welcomed Mr Hipkins.

""I have known Chris Hipkins for many years and have worked with him as part of two multi-party governments. What I have seen in that time is someone dedicated to making Aotearoa a better, fairer place," co-leader James Shaw said.

"Chris will make an excellent prime minister and we look forward to continuing our work together, for the rest of this term and the next."

Mr Hipkins said he had been blown away by the responses, to the extent that he hadn't been able to read them all.

"There are so many messages on my phone at the moment I'm not sure I could give you a definitive answer of who else I've heard from," he said.

"I've been really, really, really just warmed by the level of support I've had."
