The Greens say Maori support legalising cannabis, because they've been bearing the sharp brunt of the war on drugs

A Horizon Research poll shows 75 percent of Maori support full legalisation of the drug.

Co-leader Marama Davidson says Maori are much more likely to get a cannabis conviction than anyone else.

She says that's why there's a strong appetite among Maori to change to a harm reduction approach to drug use in New Zealand.
