New Zealanders will find out just how much they will pocket from the coalition government's tax cuts when the full 2024 budget is unveiled this afternoon.

The government has already made a series of pre-budget announcements to clear the decks for today's tax relief set piece.

National campaigned on giving families on average incomes with young children up to $250 a fortnight, but the exact detail of today's tax relief will depend on what the three coalition parties have also agreed.

Finance Minister Nicola Willis has already confirmed changes to income tax brackets will be announced today.

She says people will be happy with what they get, although voters RNZ has spoken to have a gloomier outlook.

Tax sceptics

Some people are skeptical about the tax cuts making a difference in their lives.

"Definitely not. We have our own business. Moved back from Australia four years ago, and dying to get back there now," one man says.

"Not much from this government, at all," a woman says.

"I expect nothing and I'm sure I won't be disappointed," another man says.

Almost everyone RNZ spoke too say things felt tough and many suggest the money for tax relief will be better spent on other things.

"I'd far rather see hospitals, nurses, doctors, schools, rather than give us tax cut," one woman says.

"We've got rental property, but I don't want us to be better off, we're fine. I want people who are struggling to be better off," another woman says.

"It would be lovely if it could be going to those with the children who need it," another woman says.

Concerns over further cuts

Both Labour and the Greens have raised concerns about the potential for further cuts in today's budget.

"Every time they say we had to make tough choices, we had to cut this or we couldn't fund that, the real question is why was the $2.9 billion they prioritised for landlords more important than the things they've said they're not funding," says Opposition leader Chris Hipkins.

"They're making tough choices to hand $2.9 billion in tax cuts to landlords. That money could go a really long way to fixing our education, healthcare and housing systems," says Green Party co-leader Chlöe Swarbrick.

There will be a lot of action both in and outside of Parliament today as Te Paati Māori organises a strike to protest the coalition's policies affecting Māori.

"Thousands of people from all over the country will be turning up," says co-leader Rawiri Waititi.

"It's mokopuna friendly and making sure that our people's voices are heard and we're looking forward to an awesome, positive day."

Journalists and economists will get their first chance to look at the budget later this morning, before the details go public at 2pm. You can watch the full Budget announcement live on SunLive from 2pm.

The coalition has promised a tax calculator will go up on the Treasury website, so anyone can work out exactly how much they will get.
