New Zealand Airsoft Laws
Single-shot and semi-automatic (all automatic weapons require a special restricted endorsement) air-powered weapons are legal to posses and use in New Zealand, provided that the person is either over 18 years of age, or 16 with a firearms license. A person under 18 may not posses an air gun but may use one under the direct supervision of someone over 18 or a firearms license holder.
It is illegal to use these weapons in any manner that may endanger or intimidate members of the public (pointing, brandishing, etc) except where there is reasonable cause, such as an Airsoft game.
