Another graph from David. I don't know enough off the top of my head to see the pattern but he says the pro-change vote aligns to National seats, particularly in the South Island. Also the strong no-change vote in Winston country. Obviously the Maori seats are excluded in this picture. They all voted strongly for the status quo (but with low turn-out).
