Three Head Hunters gang members are facing charges for allegedly selling methamphetamine in Wairarapa.
The men were netted as part of Operation Frozen by Wairarapa police and the National Organised Crime Group.
The three men, aged 24, 25 and 29, were all charged with offences relating to the sale and distribution of the drug.
Detective Senior Sergeant Nick Pritchard said the investigation had exposed a distribution network involving the Head Hunters gang that extended beyond the Wairarapa.
"The investigation is ongoing and there may be further arrests in coming days."
Wairarapa Detective Senior Sergeant Barry Bysouth said police were determined to clear methamphetamine dealing out of the community.
"I'd like to encourage anyone who is either struggling with methamphetamine themselves, or who knows someone who is to seek help."
