Detective Senior Sergeant John Wilson of the Bay of Plenty Police said the investigation had targeted a small group allegedly involved in dealing in significant amounts of methamphetamine in the Bay of Plenty.
"All those in the group are either patched members of the Head Hunters or are associated to that gang.
"Make no mistake, methamphetamine is a scourge, and peddling this misery is all about organised crime and making money.
"The damage that this drug does to our communities is immense, and operations like this one targeting those who would seek to make money from the addictions and misfortunes of others sends a clear signal that crime, in the end, does not pay," he said.
