NZ Election 2020: Tempers flaring and energy levels flagging in final days of protracted election campaign

Two days to go and this election is shaping up to be very unusual because almost half of New Zealanders have already voted - of the 3.5 million eligible voters, more than 1.5 million have cast an early vote. 

The election campaign is in overdrive with tempers flaring and energy levels flagging. It's a recipe for mayhem ahead of Friday, the final day of this epic and protracted election campaign. 

Labour leader Jacinda Ardern and National leader Judith Collins are in the ultimate fight for the future of New Zealand, and they continued their campaigns on Thursday in the country's biggest city. 

Ardern got a private viewing of the yet-to-premiere musical Mary Poppins, the Labour leader confirming that she cannot sing, despite BBC's Spitting image seeing things differently. 

The UK show created a parody of Ardern as Mary Poppins, painting her as a singing socialist, nanny-state dictator - and Ardern saw the funny side of it. 

"I can't imagine anyone I would like to be likened to more," she said during a tour of the Mary Poppins production in Auckland. 

"I think all intended as good sport," Ardern told reporters, when asked how she felt about being portrayed as a nanny-state socialist. 

Collins is - or at least was - a Mary Poppins fan too. 

"When I was a child I liked it but I also knew it wasn't real, thank you," she told reporters in Auckland. 

Collins' penultimate campaign stop was a business visit. As for National's campaign as a whole, she described it as "relentless - relentlessly positive". 

It was a dig at Ardern promising to bring "relentless positivity" to the party ahead of the 2017 election campaign.

Collins described Labour's campaign as "sort of, I don't know, love and hugs", while Ardern said it was "high energy". 

Collins has hit out at the media as pathetic and biased for showing Ardern's campaign mall visits - thronged by supporters - alongside her more scaled-back walkabouts. 

"Have I attacked the media?" Collins asked. "Oh really? I've given helpful hints."

"I've never gone into comparisons," Ardern said, when asked if it's unfair to compare her mall visits to Collins' walkabouts. 

The mall visits don't always go well. On Wednesday in Christchurch, abuse was hurled at the Imam from Al Noor mosque. 

"Very unfortunately, someone who obviously holds a view that is held by very, very few, expressed an opinion that I can only describe as racist," Ardern said of the incident. 

Ardern pulled Gamal Fouda away. 

"I shared my opinion back and then we all moved on," she said. "I told her that there was no place for opinions like that."

Ardern's mall visits won't stop there - she has three on Friday and then that's a wrap. 

"The chance for people to digest new policy is really, really gone. You try to meet people in the middle of the day, you go to where they are," she said. 

Collins is spending her final day on the trail waving signs and taking volunteers to lunch - and she's not giving up hope of a victory. 

"I never give up, see I'm just not like that," she said. 

Both leaders are preparing for the ultimate final round. 

"See you in a mall sometime soon," Ardern said, as she departed her press conference. 

In politics predicting a knock-out is a fool's game.
