In his latest book, investigative reporter Jared Savage explains how the illicit drug trade, depicted in big budget movies or television like Netflix's Narcos, is happening here.
Underworld is the third in his series delving into organised crime and the drug trade.
It traces the cartels and organised crime groups who are fuelling much of the activity and at the same time it becoming more sophisticated and ambitious.
The Drug Use in Aotearoa report has found consumption has surged by 229% in recent years.
Jared Savage joins Kathryn to talk about Underworld - a follow up to his bestsellers Gangland and Gangster's Paradise.
