Sixteen people have been arrested and approximately $1 million in assets has been seized after a major drug bust of a Mongrel Mob chapter.
Police said the Tuesday search warrants followed a significant operation by the Hawke's Bay Organised Crime Unit, targeting the sale of methamphetamine and cannabis.
The majority of those arrested on Tuesday were either patched members of the Mongrel Mob or their associates. It is understood the chapter mostly targeted in the bust is the Mongrel Mob Riders.
Police said they had located methamphetamine, cash, cannabis and 10 firearms.

Most of those arrested, who range in age from 18 to 46, will be appearing in the Hastings District Court on May 20, facing a number of serious drug and firearms charges.
Those arrested include the leader of a Hawke's Bay Mongrel Mob chapter.
Assets seized include a house, vehicles and motorbikes, as well as approximately $400,000 in cash.
"This morning's warrants are the culmination of an ongoing operation by the Organised Crime Unit into the sale of methamphetamine and cannabis throughout Hawke's Bay," Detective Inspector Mike Foster said.
"Organised crime is all about money. Attacking the profits of organised criminal groups is a key part of our strategy to deter and disrupt their operations, and combat the illegal activities they're involved in."
The warrants executed today were related to the recent arrest of three senior Mongrel Mob members in Auckland and Flaxmere.
Approximately $315,000 cash was located and seized in relation to those three arrests, and all three men were jointly charged with conspiracy to supply methamphetamine.
