One gang member was arrested as well as a second man.
A 22-year-old man was due to appear in the Ōpōtiki District Court on charges of possession of class A drugs, possession of class C drugs and unlawful possession of ammunition.
The second man, aged 36, was to appear in the same court on charges of possession of offensive weapons.
Both appearances were due to take place on Thursday.
