On Thursday local time police arrested four men and one woman, after a long-running investigation into the importation and sale of a Class C drug known as Brown Sugar, Mephedrone, or Drone.
The operation began in November last year.
Police seized over $405,000 cash, about six kilograms of the drug, and seven vehicles including two Harley Davidson motorcycles, an Audi, a Mercedes, and a Maserati.
They also took $200,000 of Bitcoin and other crypto-currencies.
Two of the men arrested have been charged with a range of drug-related offences, and will appear in the Wellington District Court today.
The other three were due to appear in court on Monday.
Anyone dealing drugs could expect to be a target of similar operations Wellington acting detective senior sergeant Shane Dye said, using the arrests to issue a warning to other drug dealers.
“If you are a drug dealer of any kind, we will come after you – we will hold you to account and we will restrain and obtain forfeiture of your assets.
“We hear a lot about the harmful impact of Class A drugs like methamphetamine, but this drug – and others like it – are also doing real harm.”
