The What’s My Number marketing campaign was designed to motivate consumers to check they are on the best power deal for them. When more consumers actively shop around for the best deal, the more competitive retailers need to be.

To make it easier for people to check, the Authority merged What's My Number with Consumer NZ's Powerswitch website. To learn more about the merge, read our media release.
