Methven farmer Hamish Marr supplied Wattie's with peas for around 20 years, and said the news was devastating for staff and growers alike. Associate energy minister Shane Jones pointed the finger at electricity gentailers - the major companies that both generate and wholesale electricity.

That's why the electricity sector either has to be regulated or cut in half."
