New Zealanders have been switching electricity providers in record numbers looking for cheaper deals.
An all-time high 237,000 consumers switched companies in the first seven months of 2011, 35,000 more than for the same period last year.
The What's My Number television advertisement campaign seen on television is being credited with greatly influencing the increased switches.
The campaign is being run by the Electricity Authority in partnership with the Ministry of Consumer Affairs and Consumer New Zealand to show New Zealanders what their power savings can be if they shop around.
Electricity Authority chief executive Carl Hansen said today the campaign's goal was to enhance competition in the sector.
