He told RNZ's Morning Report programme today when the new government is formed, Parliament will run for longer before Christmas and expects it will need to start earlier in the new year.
Asked if everyone was aware of this he said: "Well, no disrespect, but that's what happens for the rest of the country. New Zealanders... work up till Christmas, they take Christmas break and then they get back into it in the new year. It's very similar here, I think."
There was work to do, he said.
"New Zealanders voted for change, we've got a lot to get through, if we start earlier and have to finish later, so be it."
The election result gives National and ACT a slim majority, but a final deal will need to wait until the 570,000 special votes were counted by November 3. It may mean National would also need support from Winston Peters' party New Zealand First.
Luxon said good progress was being made in coalition talks with ACT and NZ First, but "there's still a long way to go".
"We're using the time between now and the special votes to make sure that we continue to move things forward."
The talks had been moved to Auckland as a matter of logistics - though they were not exclusively in the city, he said.
"We're following a process, trust the process, I know it's different and it's frustrating for people but we've got to just work through this process to make sure we've got a good, strong stable government."
The process would take as long as it takes, he said.
Luxon would not be going to Sunday's Rugby World Cup final in Paris as he said his focus was on forming a government.
"But I'm very proud of the All Blacks... and I'm very confident we're going to win."
NZ position on Israel-Gaza
Luxon was asked what he was being told about the situation in Gaza, where a humanitarian crisis is unfolding.
The enclave has been bombarded by Israel after Hamas militants launched a deadly surprise attack on October 27. Thousands have been killed on both sides and international concern is growing it could spread to wider conflict in the Middle East.
"I think it's important the (Labour) government is the government until the new government's formed, they're taking the lead of New Zealand's response to the situation," he said.
"They're doing a good job of keeping us closely involved and informed and also consulted during that transition period but the bottom line is that we condemn Hamas' terrorist attacks on Israel and we support Israel's rights to defend itself.
"We do want to see both sides acting in full compliance with international law and their obligations."
Asked if it was important New Zealand used its voice on the international stage, Luxon said he understood there would be an opportunity to do that at the UN and there would be a statement made at that time.
"But right now the priority is the protection of civilians and humanitarian assistance and making sure those corridors are opened up to be able to get relief to people but as I said, our position's pretty clear and united..."
The New Zealand government is contributing $5 million to address urgent humanitarian needs in Israel, Gaza and the West Bank.
The decision for aid had been made after consultation with Luxon, outgoing Prime Minister Chris Hipkins' statement on the aid funding read.
