MainPower is one of a number of community-owned lines companies in New Zealand.  We were originally called the North Canterbury Electric Power Board and have had a very important relationship with our family of customers since our very early days.


Our customers in the communities of North Canterbury and Kaikoura own MainPower New Zealand Limited through the MainPower Trust.  The MainPower Trust holds the shares in MainPower New Zealand Limited for the customers and community of North Canterbury and Kaikoura.  Our customers elect the Trustees.


Community 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 monthly Customer Rebate which is paid out monthly on to power accounts.  Annually around $7 million is paid in customer rebates.


MainPower also provides profit distribution in the form of community initiatives.
