The country's big four electricity providers are being accused of abusing their power. 

Electric Kiwi is taking a complaint to the Commerce Commission, claiming that Meridian, Mercury, Genesis, and Contact are taking advantage of their market dominance and driving out competition. 

Chief Executive Luke Blincoe told Kate Hawkesby the complaint is extensive. 

He says there are 37 pages of examples of actual refusal to supply some hedge products and constructive refusal to supply, meaning prices are offered but they're well outside the market.  

Mercury is rejecting Electric Kiwis' claim, saying it supplies hedge products to Electric Kiwi and other retailers. 

It claims the electricity market is highly competitive.
