The police have uncovered a sophisticated money laundering operation connected with the seizure of 46 kilograms of cocaine in Tauranga last week, they say.
The cocaine, with a street value of about $20 million, was smuggled on a commercial ship.
Officers arrested two Aucklanders today and charged them with laundering hundreds of thousands of dollars.
They also seized a car, a motorbike, electronic equipment, thousands of dollars in cash and a money counting machine.
Last week two Australians, a Croatian and a Serbian were charged with importing cocaine and possessing the drug for supply.
The two Aucklanders will appear in the Auckland District Court on 14 November.
