What’s My Number is a marketing campaign 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 has merged What's My Number with Consumer NZ's Powerswitch website. To learn more about the merge, read our media release.
