No, I'm sorry. That wouldn't be right. Referenda are required for fundamental changes. When I say they are required, if it's an entrenched provision, one of those provisions contained in section 268—for example, the method of voting—that would require either a 75% majority of members in the House or a referendum to confirm. Any other amendment to the Electoral Act can be made by way of a simple majority, but the tradition in New Zealand is that if it is a fundamental change either to the overall electoral system or to some feature of it, such as a term of Parliament, then that needs to be confirmed by a referendum of voters.
