The man who has gang links is now before the Whangārei District Court and police have not ruled out laying further charges.
This is the second search warrant conducted by the Whangārei Organised Crime Unit recently as it cracks down on gang members with firearms.
At the end of last month, two firearms, a stolen vehicle and a drug lab were discovered at a property on State Highway 14 near Whangārei.
A 58-year-old man was charged with unlawful possession of firearms and receiving property.
Acting Detective Inspector Kevan Verry said police were continuing to focus on gang activities and firearm-related violence in a bid to disrupt organised crime groups and the harm their actions caused in the community.
"The social impact cannot be underestimated and police will continue to take a zero-tolerance approach."
