Labour's Leader says decriminalisation of cannabis isn't a priority for his party.

Asked where Labour stands on the issue, Leader David Cunliffe says it'd be a conscience vote for individual MPs.

But he believes people's priorities are elsewhere with jobs and families.

"I don't support decriminalisation. I do want to take a harm based approach and a health based approach. I'm personally comfortable with a summary offence for personal possession, but that's a matter of conscience."
