Justice Minister Andrew Little has released the draft bill for all political parties to provide feedback on and the first step of a public education campaign ahead of the country going to the polls in 2020.

The public will be asked a simple yes/no referendum question and if it passes, Parliament will then pass legislation to make it lawful.

If the referendum results in a no vote, then the status quo will continue.

The bill includes a minimum age of 20 to use and purchase cannabis, and controls will ensure the potency of the products are regulated.

It also allows for a state licensing regime of cannabis-infused products, such as edibles.

There will also be a purchasing limit - users will only be able to buy a maximum of 14 grams per day - and there will also a limit on the total amount of cannabis grown under licence.

Mr Little has invited representatives from each party represented in Parliament to meet with him on Thursday to provide their feedback on the draft bill.

"My aim is to have the final draft Bill available by early next year, so there is time to argue for change,'' he said.

In late October, Mr Little announced plans to combat misinformation and manipulation in any campaigns leading up to the cannabis and the End of Life Choice bills.

The plans included a special team within the Ministry of Justice to direct people to information aimed to be as accurate and neutral as possible, and to be on the look-out for any attempts to deliberately mislead the public.
