Mt Albert by-election: Door-knocking underway

Labour's Jacinda Ardern has been pounding the footpath with just over a month until the Mt Albert by-election.

Her campaign officially kicks off at 1pm on Sunday afternoon. She was only officially confirmed the party's candidate a week-and-a-half ago, and the short turnaround means she's had to act fast.

"We've really had to hit the ground running. We'll be treating this like any other campaign - making sure we're out door-knocking, talking to as many people as possible, talking about issues people in Mt Albert are concerned about."

The by-election is scheduled for February 25. The winner will replace Labour's David Shearer, who resigned from Parliament last year to lead United Nations peacekeeping missions in South Sudan.

Mr Shearer won the seat in 2014 with more than 20,900 votes over National's 10,300. The Green Party scored a little over 3000.

"Outdoor knocking, the question I'm asking is really what the issues are that people want to talk to me about, and the things they are concerned about, and the things that are going well."

Labour leader Andrew Little will be attending Ms Ardern's campaign launch at the Mt Albert YMCA.

National is not running a candidate. The seat is considered generally safe for Labour. Ms Ardern's only real competition will come from allies the Greens, in the form of current list MP Julie Anne Genter.

"Whichever of us Mt Albert vote for, they will get a competent, experienced MP committed to a fairer New Zealand," Ms Genter said earlier this month.

Three other candidates have also put themselves in the running - Socialist Aotearoa's Joe Carolan, People's Party's Vin Tomar and independent Penny Bright.
