The fourth issue being considered by the MMP Review is the questions of open or closed lists. Currently we have closed lists in New Zealand. In a closed system, the party determines the order of candidates on its list, and voters are not able to express a preference for a particular candidate. In an open list system voters are able to rank the candidates on the party list.
Firstly it is important to note that an open party list system is unworkable. It is simply too complicated for the average voter to understand and voting should not be complicated. We can always dream of a more politically engaged voting public however it is hard to image anyone but the most ardent Young Labour members ranking all seventy candidates on the list.
Secondly if you dislike a parties list there is a much simpler and elegant solution, don't vote for them.
