How To Buy A Gun
We can only ship guns to licenced firearm owner's living in New Zealand.
If you do not have a licence then consider applying. The process is outlined here on the NZ Police website.
All firearms and serialised receivers require a mail order form to be completed. Download the mail order form here , print it, and take it to your local police station. The police officer receiving it will then validate your licence, sign / stamp it and email a scanned copy of the form to us. Once we receive the mail order from the police we will disptach the firearm or receiver.
We do not stock E Category firearms but can act as your agent for import. However we recommend using the POL67X method instead as being quicker and more reliable than applying to police for an import permit. You can download a POL67X form here.
