Jacinda Ardern has confirmed the Government she leads will dump the tax cuts planned by National.
Ardern has also suggested a planned referendum on legalising cannabis for personal use could be binding.
The Labour leader addressed media at Parliament today after a caucus meeting that elected the 21 Labour Ministers who will serve in the new Government, along with ministers from NZ First and the Greens.
Ardern confirmed National's tax cut package would be cancelled. New Zealand First and the Green Party both voted in favour of the package.
"It means dumping National's plans and replacing it with Labour's tax package which is substantially more generous to lower and middle income families."
Policy agreements will be released in full next week but Ardern revealed more about what New Zealanders can expect from their new Government.
That included a public referendum on legalising cannabis for personal use, to be held by the 2020 election and part of the agreement with the Greens.
Significantly, Ardern suggested that could be a binding referendum - meaning the result will need to be acted upon on implemented.
"That might be a conversation we have as an executive. I think if you go to the New Zealand public on an issue like that and it is a conscience vote then we really should place some weight on the public of New Zealand's view."
Asked how she would vote, Ardern did not give a definitive answer.
"I've always been very open about the fact I do not believe that people should be imprisoned for personal use...on the flip-side, I also have concerns around young people accessing a product which can clearly do harm and damage them.
"I'll be looking to see where the debate takes us, the view from the public, and whether or not we can find a workable solution...what we have right now which is a justice-based approach to cannabis in this country isn't working. We can do better."
Ardern said her Government would introduce a Zero Carbon Act, an independent climate commission, and "making sure we have an all-gasses, all-sectors Emissions Trading Scheme".
"We all agree as well the need for having a tool to reach our goals. And that includes a price on carbon.
"It would only be fair of me to reflect that there was advocacy from New Zealand First around making sure there is support for the regions and that will be reflected strongly in our agreement with them."
The Greens' policy includes replacing the Emissions Trading Scheme (ETS) with a Kiwi Climate Fund that will charge polluters more. NZ First wants to abolish the ETS and invest money in other actions including research and development.
Ardern repeated her view that a public conversation and debate about New Zealand becoming a Republic needs to be had, but said it would not be a priority in the coming term.
Labour's 100 day plan will broadly stay the same, Ardern said, with a "very few" elements that might change.
"At this stage I believe we may have one addition and one subtraction. But otherwise it will essentially stay the same."
The 100 Day Plan released during the campaign includes:
