That's because Parliament will decide.
The change of the Constitution says it must be created and that it's not at the whim of a future government to abolish it.
The meat and potatoes of how many, who, when etc will go through as an act of Parliament so your local MP gets a say
The pamphlets are for the people who decide in the voting booth, it's worthwhile to look for more detail on the questions you have.
I'm voting Yes for two main reasons.
When I look at NZ and the recognition of the Maori I feel embarassed that we have the oldest continuous civilization on the planet and we don't give a shit about it at all.
We haven't moved the dial on any of the major markers impacting indigenous people in the last twenty years. Perhaps it's time we actually started listening and giving them a voice isn't a bad start.
Also there's nobody on the No side I have any respect for. Jacinta Price and Warren Mundine are Opportunists, Lidia Thorpe is just the other side of the same coin. That tells me enough about the right side to be on.
