The section 16 of the Arms Act 1983 requires that:
•A person must not, otherwise than pursuant to a permit issued to the person by a member of the Police, bring or cause to be brought or sent into New Zealand— •(a) a firearm, pistol, military style semi-automatic firearm, starting pistol, restricted airgun, or restricted weapon; or
•(b) any part of a firearm, pistol, military style semi-automatic firearm, starting pistol, or restricted weapon.


In terms of ‘parts’. ‘Part’ is defined in section 2 of the Arms Act 1983 as:
•part— •(a) in relation to a pistol, restricted weapon, or military style semi-automatic firearm, includes any thing, such as a butt, stock, magazine, silencer, or sight, which, while not essential for the discharge by a pistol, restricted weapon, or military style semi-automatic firearm of any shot, bullet, missile, or other projectile, is designed or intended to be an integral part of a pistol, restricted weapon, or military style semi-automatic firearm; and
•(b) in relation to any other firearm, means the action for that firearm


Section 18 of the Arms Act 1983 provides for the issuance of permits to import for the purposes of section 16 of the Arms Act 1983. There is no provision for Police to issue a permit to import for components of firearms, other than those that fall within the definition of ‘part’ above.

To summarise, the only component of a firearm (that is not a pistol, restricted weapon or MSSA) that requires a permit to import is the action of that firearm.

Police do not have a practice of issuing a letter stating that a component does not require a permit to import and suggest that if further information is required by overseas authorities, reference can be made to this information on the New Zealand Police website.
