Wairarapa police arrested three people over the past two days as part of preventing organised crime in the area through the ongoing Operation Cobalt.
The armed offenders squad helped carry out several search warrants, which led to firearms, drugs and cash being found and seized.
Police also impounded five vehicles and seized cash for unpaid fines and issued “a number” of infringement notices.
Of the three arrests, a 30-year-old man was charged with two counts of unlawful possession of a firearm, unlawful possession of ammunition, and possession of methamphetamine.
A 30-year-old woman was charged with breaching bail, and a 20-year-old man was charged with possession for supply of cannabis.
