Twenty men and five women have been arrested as part of a six-month-long investigation into organised crime and the distribution of illicit drugs in the Bay of Plenty region involving more than 300 police staff.
Operation Notus was launched in October 2017 after the community contacted police with concerns about the social harm being caused by an organised crime group operating in the area.
The investigation identified members and associates of the Kawerau Mongrel Mob were involved in the commercial distribution of methamphetamine and cannabis to the community.
Eastern Bay of Plenty Area Commander Inspector Kevin Taylor said the investigation had required significant work by district staff and the National Organised Crime Group.
More than 300 staff were involved in today's termination including; Bay of Plenty staff, National Organised Crime Group, Armed Offenders Squad and the Asset Recovery Unit.
