Police have shut down two sophisticated drug rings and seized methamphetamine worth up to $123 million during a series of busts across Auckland.
In two drug investigations, Operation Wand and Operation Sorrento, the police Organised and Financial Crime Agency (OFCANZ) worked with Customs to target two organised criminal groups.
Detective Inspector Bruce Good said the two operations shut down criminal groups that had gone to great lengths to avoid detection.
"This included new techniques for importation and production which we have not seen in New Zealand before."
In late March, detectives and customs investigators working on Operation Wand carried out search warrants across the Auckland region, seizing 83kg of methamphetamine with an estimated street value of up to $83 million.
