I need to point out an exception to the new, continuous model. In order to help protect against roll changes by election voting which does not reflect an elector's general election roll preference, changing of rolls will not be permitted for electors who reside in an electorate where there is a parliamentary by-election during that period for that by-election. The recent by-election in Tauranga, for example, would have been just that kind of case. This exception will not, however, apply in the rare circumstance where a parliamentary by-election happens to take place during the period of the triennial local elections. This is to ensure that Māori voters can exercise their choice of roll preference for local elections separately from that for parliamentary elections.
