Police have made dozens of arrests, as part of an operation into the Barbarian chapter of the Mongrel Mob in Ōpōtiki.
Detective Superintendent Greg Williams said the bulk of the arrests were Opotiki.
"This is because the group, we allege, was involved in distribution of meth to other gangs across the country."
Williams said taking out "this significant gang" would allow the town to breathe.
Their investigation was part of Operation Highwater, which started in December last year.
He said the investigation primarily focused on the east chapter of the Barbarian motorcycle gang's involvement in drug dealing.
"It also encompassed a significant amount of violence that the gang was also engaged in."
He said the Ōpōtiki-based gang, had caused significant violence and issues.
Williams said, the group is believed to be involved in the distribution of meth to other gangs around NZ.
Bay of Plenty District Commander, Superintendent Tim Anderson said today is a good day for Ōpōtiki.
Anderson said the arrests are a "clear message to gang members selling illegal drugs across the Bay of Plenty that we will find you and you will be held accountable for your destructive behaviour."
“We will continue to relentlessly pursue criminals who prey on our communities and cause a huge amount of harm and misery in their own communities with their drug dealing and violent behaviour," Anderson said.
He said iwi leaders and the community have had enough of this type of criminal offending.
