New Labour billboards revealed - and they're not red

With a new leader comes a fresh new look for the Labour Party, which officially revealed its updated campaign billboards today.

On a white backdrop, Jacinda Ardern stands centre in the new-look election hoardings, with a bright red banner across the bottom urging the public: "Let's do this".

"They really pop, don't you think?" she said.

"So much of it is just about that visual and so that's our focus this campaign - making sure people certainly notice our billboards in amongst...others."

Ardern unveiled the party's new look on Bond St, central Auckland, where other parties' election hoardings stood nearby, including one featuring the Greens' Metiria Turei as co-leader, due to be replaced.

A crowd of young Labour supporters also turned out, wearing white T-shirts bearing Labour's new slogan.

They were in good spirits and were quick to call out "Go Labour" while punching the air every time a car tooted.

Earlier, a worker was seen taking down the old billboard with former leader Andrew Little, before stuffing it unceremoniously into the boot of his vehicle.

Ardern thanked her team for the work they had carried out in a matter of just a few weeks to design the new hoardings and make sure they were ready to be put up all around the country before the party's election campaign launch on Sunday.

"From the outset, we were told when we were redesigning the campaign, that it would take a couple of weeks. Now we've got volunteers from around the country who will be working really hard to get these up over the weekend.

"This marks the beginning of our campaign officially launching on Sunday and a huge amount of work goes into hoardings.

"There's so much energy in this campaign. I doubt we'll have any complaints about that, so thanks team, for joining us today."

Asked how much the new boards cost, she did not know; but acknowledged that it was a cost - which also included redesigning flyers and some campaign advertisements - they had accepted.

She also took the opportunity to touch on results from a 1 News Colmar Brunton poll, which showed she had rocketed up to 30 per cent as the preferred Prime Minister.

"I certainly find that heartening.

"But again, I want to make sure that I earn every single vote and ultimately, those preferred PM stakes - unless they're translating to party vote - doesn't change our relative position to govern. So that's got to be my focus."

After hauling up her new-look billboard, Ardern and some supporters then turned and walked towards another billboard that looked to have fallen down.

As they turned it over, Prime Minister Bill English's face could be seen. The Labour team then went to work to get it back up again.

A man in the crowd commented: "She shouldn't even touch that."

The Labour Party is expected to reveal its campaign song at their launch on Sunday in Auckland.

Asked by media whether moves had been made to make sure there were no legal issues associated with using a particular song, she replied: "Always."

"No Eminem," she laughed.

It is expected the party will use a song by a New Zealand artist.
