Police have arrested every single known patched member of the outlawed Australian Rebels motorbike gang in Taranaki, and others in Northland.
The Rebels - known for dealing in illegal drugs - started forming a chapter here last year.
Detective Inspector Chris Bensemann from Palmerston North says it was a multi-region approach to try and stop the Rebels gaining a foothold in the methamphetamine trade.
"Those think of joining the ranks should think twice," says Mr Bensemann. "They can expect to place themselves directly in our line of sight should they begin their association with Rebels gang members or the Rebels gang itself."
Mr Bensemann says yesterday's operation involved about 80 police officers from central and Northland districts.
