Four people have been arrested on drug charges in Bay of Plenty following a police investigation targeting the Head Hunters.
Police said several properties in Tauranga and Opotiki were searched today and further arrests could be made.
The patched members or associates of the motorcycle gang all face several charges relating to methamphetamine dealing and cannabis cultivation.
The police said the year-long investigation has targeted a small group involved in dealing significant amounts of methamphetamine in the region.
More than half a million dollars of cash and four guns had been seized over the year, they said.
