We can't wait another three years, Labour leader Jacinda Ardern urges voters as she winds up her campaign

Labour leader Jacinda Ardern has wound up the last day of the campaign with a plea to voters who believe she needs to serve more time as leader before becoming Prime Minister.

Ardern has just completed the last two walkabouts of shopping malls on her campaign - in Manukau and Henderson - and will end the day campaigning in her Mt Albert electorate tonight.

Speaking after the Manukau mall visit, Ardern said she had not had much time to pull her campaign together since elected Labour leader on August 1.

"I would have liked more time. I know there will be voters out there who will be thinking just a little bit more time to perhaps get to know me and my style of leadership - but we can't wait another three years.

So my message to them was there is a sense of urgency - we need to tackle those big issues. We can't be on autopilot for three more years."

She said she knew there was a lot of expectation on her. "And I've given it all I've got."

Ardern said it had been "a day of highs and lows" after had going to her grandmother's funeral in Te Aroha. Her grandmother had died on Monday night, a day after Ardern had gone to visit her.

"My grandmother was a wonderful woman, I know she would have liked to have been her for tomorrow. Family first, so it was really important to me to get to her funeral and her service today."

She believed there was a mood for change.

Ardern said it could be some time after the election before a future government became clear - and some results could be dependent on special votes which would not be counted and declared until October 7.

"I'm sure there will be enough will and desire, certainly among the main parties, to want to resolve coalition negotiations as soon as practicably possible."
