A prediction we haven't seen the last of a transnational crime syndicate operating out of Auckland airport.

Operation Matata's seen 43 arrests since February, including 20 border workers - allegedly involved with smuggling large quantities of meth and cocaine. 

It's thought the group were exploiting baggage handlers at the airport. 

Chair of the ministerial advisory group on organised crime Steve Symon told Heather du Plessis-Allan that authorities have done a fantastic job rooting out that many offenders. 

But he suspects either there are more, or if not, they'll be replaced like they were at the start of the year.
