The next issue in the MMP Review is should list MPs be allowed to contest by-elections (without first resigning their list seats)?
I have to agree with Dimpost on this one: Why not?
I don't believe we expect anyone else to resign their job to contest a by-election so why should a list MP. The people of the electorate are entitled to as wide a field of candidates as possible, if they don't like a list MP standing then they don't vote for them. It is as simple as that.
I think it would be much more interesting to consider banning an MP who's resignation triggers a by-election from contesting that by-election (Stand up Hone Harawira!).
