The issue here that the Labour is trying to fix, or the problem it's trying to find, is the option for switching in and out of the Māori roll and on to the general roll, or from the general roll on to the Māori roll. That can happen at any time in the electoral cycle and it has no restrictions on the number of times that voters—electors—can choose to switch on those rolls. It seems to me that there's a recipe for disaster—what a mess it's going to be.
