In this case they aren't even saying they should lose the status because they are horrible people, it's because they haven't filed their annual returns that charities are required to file.
Unfortunately NZ has advancing religion = charity enshrined in law, and it's political suicide to touch it.
Which I think is stupid because most small town churches will still qualify under one of the other categories. Just need some party to make the change when they are already on the way out.
