In the 1970s, the Mr Asia drug syndicate was one of the largest sellers of heroin in the world. The group began in New Zealand, with two men at its centre: Marty Johnstone and Terry Clark.

As the syndicate spread around the world, for a few years, they were living the high life. And then, they started killing each other. 

In the new season of A Forgotten History, from the New Zealand Herald and Bird of Paradise Productions, John Daniell and Noelle McCarthy revisit the lives and crimes of these two men, their associates, and how their actions changed drug culture in New Zealand.

Episodes available from February 19th.
