It's very, very helpful to have the historical understanding that it dates back to 1867.
I also wonder this. You mentioned that you've done a lot to educate the New Zealand population about the electoral system. I'm wondering what you regard as the most effective methods of education that New Zealand undertook to change from our current system of first past the post, which we want to remove, and move into proportional representation. What were the most effective ways in which this transition was made in terms of public education?
