Most Kiwis don't think recreational cannabis should be legalised.

In contrast to some earlier polls, two seperate recent surveys have shown that New Zealanders may be changing their minds about legalising recreational cannabis.

About 52 per cent of New Zealanders said they intended to vote against legalisation, the latest 1 News Colmar Brunton poll found.

Of those asked in the poll, 39 per cent of people wanted cannabis legalised, 8 per cent did not know or refused to answer, and 1 per cent said they would not vote.

A separate poll run by Newshub-Reid Research found 48 per cent of people did not agree with legalisation. While 41.7 per cent were in support of it, and 10.4 per cent didn't know.

The Government made the details of the 2020 cannabis referendum public in March. There will be a simple yes/no question for kiwis to vote on.

If the public endorsed the legislation it would legalise personal use and make the purchase age 20. It would only allow sale at licensed premises, only allow consumption at licensed premises or property. It would allow limited home-growing and also ban advertising for cannabis products.
