Incumbent Prime Minister Chris Hipkins is attending his last election campaign events on Friday, accusing the Opposition of deceiving New Zealanders while making a final appeal to voters.
Polls showed Hipkins' Labour trailing Christopher Luxon's National Party going into Saturday's general election. However, National would also require NZ First and the ACT Party to form a Government.
The race between the National-led right bloc and the left bloc comprising of Labour, the Green Party and Te Pāti Māori had tightened, however. As per the latest Newshub-Reid Research poll, the right had 63 seats and the left 57 (61 needed to govern).
Polls will start at 9am on Saturday. At 7pm, when the polls close, results will start rolling in.
Hipkins' campaign over the past six weeks has focused on the achievements of his Government, including delivering record-low unemployment and infrastructure projects. Hipkins, who took over as Labour leader after the shock resignation of Jacinda Ardern earlier this year, has asserted National would roll back developments his Government has made.
One of his talking points has been National's tax plan, saying the Opposition couldn't stack it up.
At an event in south Auckland on Friday, Hipkins said there was a "huge amount of energy and momentum" for Labour.
He said there was strong "groundswell" support for the party across New Zealand.
"The feedback that we're getting on the ground is that people are well aware of what's at risk in this election - they are increasingly frustrated and, in fact, feel deceived by the promises the National Party have made as they see what the consequences of those promises are," he said.
"New Zealanders have been doing their own math; they've worked out that next to nobody gets the full benefit of National's cut but everybody pays."
Luxon, meanwhile, spent part of the final day of the campaign at Waikato's Hampton Downs Motorsport Park - telling reporters: "We're right down to the wire.
"We've got one day to go... and the power is sitting with all Kiwi voters out there in New Zealand, and I'd just say to them, look, if you're struggling with your mortgage, if you're struggling with your rent and your food and your fuel bills, if you're not feeling safe in your own community, if you're not feeling your kids are getting a great education and setting them up for the future and if you don't think that the healthcare services are there when you need them, then I'm encouraging you to say that you need change.
"And whether you've been a lifelong Labour voter, whether you've been an undecided voter, I'm saying to you that you need to party vote National."
Luxon also criticised the incumbent Labour Government, saying it "hasn't taken us anywhere".
"We've gone backwards."
However, Hipkins told reporters he was expecting a strong result for Labour.
Both Hipkins and Luxon said they had not thought about whether they would stay on as their respective party leaders should they lose.
"I'm absolutely going full tilt to make sure that we win tomorrow," Hipkins said.
"Clearly, I want to be there for multiple terms as Prime Minister," said Luxon. "I haven't thought beyond that."
