In New Zealand, one can easily own a sophisticate gun from a teenage age.
The minimum legal age to own a gun is 16, or 18 for military-style semi-automatic weapons (MSSA)
All gun owners must have a licence but most individual weapons do not have to be registered. New Zealand is one of the few countries where this is the case.
MSSAs must be registered, but critics say loopholes in the law mean they need only be minimally modified (for example by inserting a low calibre magazine) to evade this requirement.
Applicants for a firearms licence must pass a background check of criminal and medical records.
Once a licence has been issued, gun owners can buy as many weapons as they want.
