Labour leader Andrew Little says his party wants to make it easier to access medicinal cannabis.
The Labour caucus is now debating the issue and will come up with a formal position in the next few weeks, Mr Little told reporters at Parliament this morning.
"We are aware that this is an issue and there is a willingness to look at our current policy and see whether it meets current scientific understanding," he said.
The Labour leader would not say whether the party wanted decriminalisation of marijuana use for medical purposes. But he said that the process for applying for medicinal cannabis products needed to be simpler.
"It's about accepting there is enough medical evidence around now that under proper or appropriate supervision from a GP or specialist that this isn't a form of treatment that ought to go through a series of hoops to get a ministerial sign-off."
