King Country Energy customers will soon have a change of electricity supplier from King Country Energy to Trustpower.

Trustpower has been a majority shareholder in King Country Energy for the past three years. Earlier this year Trustpower and the King Country Electric Power Trust entered into an arrangement whereby the parties agreed to acquire the balance of King Country Energy and, upon that being completed, Trustpower would acquire King Country Energy’s retail business with King Country Energy retaining the generation assets.

Trustpower is one of New Zealand’s leading suppliers of power and gas and is also New Zealand’s fastest growing phone and broadband provider. By switching you to Trustpower, in addition to providing you the value and service you’ve come to expect from King Country Energy, we also offer phone and broadband as well as reticulated and bottled gas.
