As far as I know semi-auto rifles with fixed magazines holding 7 or fewer rounds are class A firearms in NZ and anyone who can own a gun can possess them. Am I correct? A good example would be an SKS with the internal magazine blocked to hold 7 or fewer rounds. Stripper clips allow for rapid reloading.
First, for starters, you need to have a firearms licence. In order to get one, you need to pass the firearms safety exams, and pass the
"fit and proper person test". If you have ever been subject to a protection order, broken any firearms laws, committed any criminal offence, or any offence involving drugs or violence, or are connected with a criminal gang or any members of a criminal gang, or committed any act of domestic violence, then you will fail the fit and proper person test.
Now the gun. In NZ, a "type A licence is for "sporting configuration" firearms. A sporting configuration firearm is a rifle or shotgun that does not meet the legal definition of, or have any of the attributes of, a Military-Style Semi-Automatic (MSSA), "Restricted Weapon" or "pistol". NOTE: An MSSA is any firearm that has one or more of the following attributes or features.
1. a magazine that holds, or is detachable and looks like it will hold, more than 15 cartridges (for .22 rimfire)
2. a magazine that holds more than 7 cartridges, or is detachable and looks like it will hold, more than 10 cartridges (other than for .22 rimfire)
3. a folding or telescopic butt
4. a bayonet lug
5. a pistol grip
6. a flash suppressor
Basically, anything that looks or acts like an assault weapon is out, so AR15, M16, L1A1 all out.
