The Mr Asia drug ring imported large quantities of drugs into New Zealand and Australia through the 70s.
The drug ring, one of the largest New Zealand has ever seen, was led by Marty Johnstone, the original Mr Asia, and grew from marijuana imports to a massive heroin operation.
Johnstone was killed on the orders of drug lord Terry Clark, divers found his mutilated body in a flooded quarry in England.
David Lomas, investigative journalist, has followed the story since the late 70s.
