Getting the electoral system you deserve

For the past month or so, I've derived amusement from the "Vote FPP: Don't let democracy be hijacked" sign on the side of the Hutt motorway. Unfortunately, judging by today's poll results, the citizens of Hutt City fell for it, and voted to retain the system that elected John banks. And unfortunately it looks like my ex-home of Palmerston North has likewise voted to retain FPP - though by a far slimmer margin.

I wonder if Wellington will be having a poll anytime soon?
