It was the case that the impetus for electoral reform, beginning in the 1970s and early 1980s, was around dissatisfaction with the way in which first past the post was operating in New Zealand. Neither of the two main parties, which continue to be in existence and now are operating very successfully under the mixed member proportional system, advocated moving to a proportional system. Notwithstanding that, we went through a process that saw the New Zealand public have a say, and they exercised a choice to move to MMP. That was the New Zealand experience.
