- National surges ahead in latest Colmar Brunton poll
- National could govern alone in latest Newshub poll
Labour leader Jacinda Ardern is in Canterbury, and will be urging young people to get out and vote. Advance vote numbers have been high, but youth enrolment will be a concern for Labour. It's typically more popular with younger people, but on Sunday the Electoral Commission reported 68 percent of 18- to 24-year-olds are enrolled. At least 90 percent of those over 35 are enrolled.

3:25pm - Jacinda Ardern hits out at National for "farcical claim" on income tax
Jacinda Ardern has spoken out about her frustration with the National party campaign, saying they are misleading voters over Labour's tax plans.
While on the campaign trail today Ms Ardern was asked if Labour was raising income tax, a false claim that National have made.
When asked whether she could have hit back harder against the claim Ms Ardern replied:
"I've absolutely taken them on every time that they've said we would increase income tax. I thought it was a farcical claim when they raised it, it continues to be, I certainly didn't expect people to have picked up on it as they have.
"The only place for blame to go is on the party that has spun the lie."
Ms Ardern said right now there is urgency for Labour that goes beyond correcting National. "I would ask voters to think about whether they can afford another three years of National."

Ms Ardern has appeared on Mai FM, answering questions on life with security tailing her and offering advice for women.
Answering a listener question, Ms Ardern said her advice for women in male-dominated environments is 'self-belief.'
"When it comes to the ladies, we are our own worst enemy. I always look for the things I've done wrong in everything. Just your own self belief will carry you a long way."
Answering another question from a listener, Ms Ardern said security has to come with her wherever she goes during the election campaign.
For that reason, Ms Ardern said she has been "too embarrassed to go and do any exercise, because they'd have to do a run-walk with me."

9am - Bryce Edwards believes Labour have the edge
But on Thursday morning's The AM Show, political commentator Bryce Edwards said Labour's potential coalition partners give it an advantage.
"I'd say Labour have the edge - they have more coalition possibilities, they might be able to put together a coalition with NZ First or the Greens, and the Maori Party. I think they have the edge."
Speaking about the Wednesday night TVNZ debate, he said it was lacking spark.
"They did fire at times and they had their clashes, but mostly I thought it was like two sumo wrestlers leaning up against each other. Neither of them could dominate, and I think they both wish it was over... I don't think you would have seen a lot of uncommitted voters get swayed by what happened last night."
Dr Edwards said Labour's last-minute decision to wait until the next election to implement the findings of its tax working group could worry some people.
"That does trouble some voters. We're looking at a Government coming in… that's had nine years to get these things right, and they haven't. People do worry about competence, they do worry about whether Labour's ready to govern when they see them doing these changes at the last minute."
