Justice Minister Andrew Little has flagged that referenda on cannabis law reform, euthanasia and MMP reform could take place at the same time.
Speaking to TVNZ's Q&A programme last night, Little said a Cabinet paper on the cannabis referendum was with colleagues at the moment but the detail of the referendum's form, whether it's binding or not, had yet to be decided.
The Government is planning a referendum on cannabis for personal use before or at the 2020 election as part of its confidence and supply agreement with the Green Party.
"There's a Cabinet paper that's being reviewed by various Cabinet ministers at the moment and I would hope that we'll make decisions before the end of the year," Little told TVNZ.
"One of the issues is, is it binding, is it not binding. There's still the question about the timing of it and various other questions as well. But it's certainly my strong preference ... that by the end of this year we'll have those principal decisions determined so we all know."
