National Party leader Christopher Luxon is speaking to media after the election night result giving National and ACT a majority of seats in Parliament.

Luxon says he wants to focus on delivering outcomes.

He hasn't talked to Winston Peters yet: "I really appreciated Winston Peters' remarks as I commented last night, on his offer of help and wanting to act in New Zealand's interests and I respect that. I am sure in due course we will be in contact."

He says his role will be to lead a more unified country.

"We are going to bring New Zealanders together, to work together on the challenges we've got."

He says preparation over the campaign and listening to people outside of Wellington has helped them achieve this result.

He says he spoke to ACT Party leader David Seymour twice yesterday, and will work with him "in a constructive way".

They have spoken over the past couple of months often and know each other fairly well, he says, including about rebuilding the economy and law and order, which he says they are aligned on.

Watch the media conference here:

New Zealand voters gave National a mandate to lead the next government with 50 seats in Parliament and just under 39 per cent support.

National and ACT together have 61 seats in a 121-seat parliament, while Labour support fell to just under 27 per cent.

New Zealand First has eight seats with about 6.5 per cent of the vote.

Luxon says being elected prime minister is a great honour and he is humbled and energised by the support.

Last night, Luxon wasn't commenting on whether he would offer ACT leader David Seymour the role of deputy prime minister.

With special votes still to be counted it was unclear whether Luxon would have to keep the line to New Zealand First open.

Luxon says he hadn't spoken to New Zealand First leader Winston Peters, but appreciated Peters' comments offering to help if needed.

Addressing supporters last night Peters suggested there were a lot of National's promises that were not affordable and he would work to rein them in, given the chance.

"If we can help, going forward, we will," he says.
