Research released by the Helen Clark Foundation claims that 20 per cent of voters support cannabis being decriminalised, and 49 per cent support it being legalised. Thirty per cent think cannabis laws should remain unchanged or made tougher.
NZ Drug Foundation executive director Sarah Helm said the research showed overwhelming dissatisfaction with the status quo.
"We continue to see thousands of New Zealanders convicted of low-level cannabis offences , even though it is clear from the research that very few of us believe that Kiwis should be criminalised for these," she said.
"The evidence shows that cannabis convictions do absolutely nothing whatsoever to deter use . Given how ineffective our punitive approach to cannabis is, we are currently doing very little to reduce cannabis harm as a country.
"Young people, Māori and men bear the burden of cannabis convictions. And while the police and ministers are committed to trying to improve the situation, people continue to face convictions.
