The preliminary referendum results indicate that a majority of Kiwis voted against legalising cannabis for personal use.
Today's results show 46.1 per cent voted for legalised cannabis, compared to 53.1 per cent against.

Newstalk ZB political editor Barry Soper told Si and Phil it's not impossible for the cannabis vote to change, once special votes have been counted.
"It's a big change that's required, but the special votes are there for it to be changed.
