They want to abolish the Human Rights Commission
Allow unregulated overseas investment from OECD countries
Sell all or part of many state owned enterprises (e.g. sell 49% of KiwiRail).
Sell public hospital buildings to private investors
Water pollution would be managed by letting companies bid for the right to pollute up to the allowed pollution levels
They want to repeal the zero carbon (by 2050) act
They will abolish the building act, replacing it with mandatory insurance. The idea is if it's not built to a good standard then insurers won't insure.

And here are some others (some seem to overlap with National):

They want to abolish fair pay agreements
They want to abolish rules that protect valuable natural areas
They want to decrease tax for higher earners, and increase tax for lower earners
They would re-allow live exports of animals
They oppose any laws banning hate speech
They would abolish ministries for Pacific people, Ethnic communities, Women, Māori development, etc.
Reduce the rate superannuation increases each year, and stop putting money in the super fund
Remove the Matariki public holiday
Reintroduce the 90 day fire at will period
Remove or reduce government kiwisaver contributions for most workers
They want to increase the prison population (see my other comment about private prisons)
They want to introduce privately owned toll roads
They want to pay emissions trading scheme revenue back to everyone as a tax credit, instead of spending it on reducing emissions
They want to stop contractors from challenging their status, to allow employers to bully employees into being paid as a contractor to avoid paying leave entitlements and other protections
Make a literacy test a requirement to get parole (again, private prisons want people to stay longer)
Hold a referendum to introduce a rule that allows anyone to take the government to court if they think new laws don't fit a set of standards
Abolish the climate emergency response fund
I'm gonna quote this one: "This party says that the current government requires councils to review speed limits and reduce them in high-risk areas like school zones. This party believes that this is slowing people down and making society less productive."
Create a new state owned enterprise to manage roads, being required to return a profit via charging people for the use of roads (no current plans stated to sell off 49% but I think it's implied)
