MainPower is a community-owned company. The MainPower Trust holds the ownership of the company on behalf of the communities of North Canterbury and Kaikoura and for qualifying customers.

Consumer ownership of MainPower entitles customers and the local communities to a share of profit. Profit distribution is made in two ways. Qualifying customers are entitled to a customer rebate which appears on your monthly electricity bill.
