Election 2023: New Zealand First announces tax cut policy without details

There are still 83 days until New Zealanders go to the polls but most of the parties were really revving their political engines on Sunday as the campaign moved up a gear.

The Greens were rallying their troops to fight the right.

"They are using fear as a motivator because they have nothing else. No vision. No courage. No moral compass," said co-leader James Shaw.

While the old campaign king, Winston Peters, spoke up his experience.

"We are asking you to join us, and 'Let's Take Back Our Country'."

Peters last night celebrated the thirtieth birthday for his party. He cut into a cake with his face on it and then on Sunday promised to cut tax.

"We are going to ensure that the tax income brackets are adjusted to inflation."

But while Peters might have the pitch, he doesn't have the details of how much it will cost. He said details will come over the next two months. 

There's someone who has a similar policy, who could also hold Peters' political future in his hands - National's Christopher Luxon. 

With Peters ruling out working with Labour again, National ruling NZ First out would leave Peters without a path to power.

But Luxon is refusing to. 

"I am really focused on maximising the party vote for the National Party," he said. 

ACT's David Seymour said Luxon should rule out NZ First. 

"Winston Peters can't work with anyone. He has fallen out with National twice before, he has fallen out with his own MPs. People ask, David, can you work with Winston Peters? Well no one else can, why would I be able to? I am not Jesus."

Seymour sees a road to votes in, well, roads, announcing a new transport policy on Sunday.

"Under ACT's proposal, when a road is planned, if the government can't afford it, the world will be invited to submit a bid to build it, toll it, and hand it over to government after 30 years."

The Greens are thinking about the next 30 years differently.

"Losing means sitting in Opposition, frankly, and watching a right-wing populist, authoritarian Government dismantle all the progress we've made in recent decades and take us back 30 years," said Shaw. 

The parties are putting it all on the line, so strap on in, it's the campaign baby.
