Police Minister Stuart Nash believes a multi-agency approach is what is needed to effectively combat synthetic cannabis.
The Napier MP said people cannot underestimate the scale of the problem.
"It is a problem that affects all our communities and there is not just one approach. This is as much a mental health and addiction issue as it is a policing issue.
"The people who are addicted to these substances need to be able to get the help they need and the police need the ability to go after the people who are manufacturing and supplying or dealing these substances in a way that actually makes a difference."
