Labour leader Jacinda Ardern is on an Auckland walkabout blitz this morning and has filled her campaign diary with mall visits and tours of local businesses.

Her political rival, Judith Collins, is also in Auckland visiting supporters today – she will again be a "human hoarding" this afternoon.

Today is the last official day on the campaign trail for both leaders before the polls close tomorrow.

Scenes at Lynn Mall today were similar to other mall visits Ardern has done throughout the campaign.

Within seconds of getting out of her van, she was mobbed for selfies.
Most of the time, it was more of a shuffle-about rather than a walkabout.

She took more than a hundreds photos in the 40 minutes she was at the mall.

The overwhelming majority of people were fans - bar one woman who yelled 'traitor' at the Labour leader as she left the mall.

But her heckles were quickly drowned out by singing supporters.

Meanwhile, Collins spoke to media at the base of Mt Roskill, to highlight Labour's failure to build light rail through that suburb and to Auckland Airport.

She said she hadn't managed to find the "mythical" light rail, and that was one of the Labour-led Government's many failures, including KiwiBuild and other road projects being cancelled.

"We have been paying an extra 10 cents, plus GST, per litre of fuel, in the last three years to pay for this light rail."

Labour's record was "unbelievably poor", Collins said.

Later today she would help take down hoardings.

"I may well be out there in my electorate doing that. My husband is out there doing it now, so I'll be expected no doubt to go and join."

Looking back on the campaign, Collins said it had been exciting, but three months was "probably enough" - although another month would have its benefits.

"Just more opportunities to show how the current government hasn't delivered on all its promises. It doesn't matter what they promise - they won't deliver."

Collins said her plans for election day included getting her hair done. She was going to enjoy a sleep-in, too, "but then I see the hair appointment is at 9am".

"But if I can get up at 8am tomorrow, that will be about two, in some cases three hours, later than I have been doing for the last three months. So that will be pretty good."

Collins said she was confident she'd still be National leader this time next week.

"Because I know that I have the support of the caucus, and I have the support of the membership, and I have the support of the board, and I have the support of the people who vote for us.

"But I also think, too - it's very difficult for someone to roll the Prime Minister."

Collins was asked about reports from some voting stations of staff telling people they have to use QR codes and hand sanitiser, otherwise, they can't vote.

"That would seem to me to be a very interesting situation that the Electoral Commission will need to answer for. If that is true, I suggest that you contact the Electoral Commission to ask them what's going on. I may actually ask them myself."

Collins nominated a standing room-only public meeting in Palmerston North as a campaign highlight, and the second lockdown as a "difficult time".

Would she step down if National wasn't in government after the election? "Definitely not".

"Number one, I don't believe we'll lose, secondly, even if we do, then we are going to need very strong leadership. And we'll need to absolutely have stability."

Collins said she wasn't surprised that Ardern had said in last night's leaders' debate that she would resign if Labour ended up in Opposition - and predicted Ardern could further follow in Helen Clark's footsteps.

"I think she'd be off to the UN, actually."

Was she a stronger leader now than before the campaign? Collins said "we always learn from adversity and overcoming things."

Her final message to undecided voters: "If they want a National Government, their only party vote should be for National. That is absolutely crucial. No messing around - just party vote National."

Last poll puts Labour close to governing alone

Last night's 1News-Colmar Brunton poll showed there is still a sizable gap between the left and the right block

Labour are on 46 per cent and the Greens are at 8 per cent, giving the two parties more than enough support to form a government.

National, meanwhile, is at 31 per cent and Act is at 8 per cent.

On current polling, New Zealand First would not return to Parliament.

Last night, both leaders faced off in the final debate of the campaign period.

Although it was much less fiery that previous debates, it was quite revealing at times.

Ardern confirmed for the first time that she would resign if she did not win.

Speaking to media after the debate, Ardern said she has been around politics long enough to know that if you don't successfully lead your party through an election, "it is time to move on".

"That's what I would do, and that has certainly been my experience in politics."

Collins, however, said she would not be going anywhere if she loses the election tomorrow night.

"I'm the best person for the job," she said, when asked why she would not resign if she can't form a government.

Ardern starts the day at premium composites manufacturer C-Tech Limited, before heading to Lynn Mall, then South Mall.

She finishes her day at Onehunga Mall, where she will be doing a walkabout, before meeting with volunteers tonight.

Collins is having lunch with volunteers in Auckland's Browns Bay, then meeting supporters in Rosedale.
