Hi Welcome to JustAnswer. My first response will follow shortly. Please feel free to follow up if anything is not clear

The ACC legislation creates a statutory regime for compensation for injuries by accident. The nature of the legislation is that all persons who are working or self-employed must pay levies to ACC, and it is an offence not to pay the levies, either yourself if you are self-employed, or your employer not to pay the levies. It is like other insurance however, such as for your car or house, where you pay premiums for the insurance, but do not get any money back if you do not make a claim. I understand your point about the ability to choose your own health provider, but ACC is not a health provider but an insurer. They have a monopoly on personal injury insurance conferred by statute. You do not have an option of having no insurance.

I thought I had explained that ACC is a statutory obligation. The only way to become free of this statutory obligation, is to cease to be a resident of New Zealand, which is I expect, not an option for you. ACC covers everyone without exception. It is like a tax, in the sense that if you earn income you must pay tax. The question is really a political one, and of course there have been policies in the past from different political parties suggesting that there should be options to ACC with private insurers. Currently, that is not the position and I can only tell you the law and how it applies to you. You are correct that the money is taken from you because of statutory obligations. If you wanted to say that this was contrary to international human rights law, you would be most unlikely to succeed in a court in New Zealand. The religious exemption does not exist in law for ACC. So whatever your beliefs, you are stuck with the obligation to pay. I am not saying whether I agree, or disagree with your position, but I am attempting to explain that there is a statutory obligation that you cannot avoid. You cannot become in your words "free of this financial burden".

There is no law which says there is a maximum amount of tax. Tax is set by Parliament as part of the annual budget process, and the rates of tax are adjusted when required. In theory 100% tax could be imposed, but in reality the political process is such that this would never happen, because the political party which did this would be unlikely to get a silly tax bill like this passed by Parliament.

You are correct that changing the government is the only way to change the ACC policy.
