Associate Professor Mark Lauchs from the Queensland University of Technology is a specialist on an organised crime, corruption, and outlaw motorcycle gangs. He's warning Aotearoa to brace for a flood of 501 deportees in the next 12 months, many from West Sydney street gangs and Victoria's underworld. When Prime Minister Jacinda Ardern recently met with her Australian counterpart Anthony Albanese, she pushed for a change to Australia's 501 deportation policy. Mr Albanese said he was committed to working through the issues, but not to amending the policy. Mark Lauchs talks to Kathryn about the various crackdown on gangs across the Tasman and whether they've worked.
