The minor parties are puffing up their feathers, posturing as members of the next Government-in-waiting.
One revealed to Newshub exactly which job they have their eye on. And two face a nervous wait on the referendum results.
James Shaw has revealed what he's keen on: holding on to the Climate Change Ministry. Those job titles are key to the Greens.
"Most of what we achieved was not in our confidence and supply agreement, it's actually a function of having ministers and being around the table," Shaw says.
The Greens could be matched in size by ACT, which could go from a party of one to eight, based on the latest Newshub Reid-Research poll.
ACT leader David Seymour would suddenly have a team. He says he could handle that.
"Absolutely, I coached rugby for seven years," he tells Newshub.
With a caucus in tow, he'd have new mini-scandals to deal with. On Tuesday he got a taste, with his number four on the list accused of holding 'climate hysteria sceptics' meetings with the high school students he teaches.
"He was giving students that opportunity to discuss a complex topic," Seymour says.
Seymour also has a pet referendum - the End of Life Choice Bill. He's worried about misinformation getting in the way of it passing.
"I worry every day that the End of Life Choice Act may not become law," he says.
The Greens have a pet referendum too - on legalising recreational cannabis.
They're disappointed after the New Zealand Medical Association (NZMA) apologised for taking a no stance on the referendum without consulting its members so it looked like doctors and medical professionals were universally opposed.
"I'm sure that there would have been people who would have seen what the NZMA said and made their mind up on that basis," Shaw says.
The NZMA wasn't available for an interview on Tuesday. In a statement the organisation told Newshub: "We continue to be concerned about the harms of cannabis use, but we are not telling people how to vote."
There's another minor party to keep an eye on - the Māori Party in the electorate seat of Tāmaki Makaurau.
A Māori Television poll found Labour's Peeni Henare at 35 percent followed by the Māori Party's John Tamihere at 29 percent.
New Zealand First is also claiming it's seeing a surge in support - leader Winston Peters using a public meeting in Tauranga to warn of a "lurch to the left".
"We were the underdog but we are coming with a serious rush," he said.
Just don't ask about the top dogs.
"If that happens, then I'll hit the bus and hit the road because there's a lot of people to see," Peters warned.
Just four more days keeping the seats warm on the 'Back Your Future' bus.
