This is something you Americans just fail to understand. You are just about the only place in the western world where owning a firearm is a right, and the only one with a national fear that "y'all are comin' tuh take muh gunz away".
Most everywhere else, firearms ownership is a privilege, one that you have to show that you deserve to be granted, and that you have to pay for.
In NZ, there really is no equivalent of the NRA rating politicians on their position on gun ownership, no firearms lobby pressuring politicians and offering campaign contributions in exchange for favourable consideration in legislation. Gun rights advocates aren't really a "thing" here to any serious degree.
You understand that, in NZ
- handguns are almost non-existent?
- owning a firearm for self-defense is specifically outlawed
- there is no "stand your ground" law
- there is no right to carry firearms in public
- there is no right to shoot people on your property even if they are committing a crime
