Key: Inquiry needed after power cuts

Prime Minister John Key says an inquiry is needed into whether there was sufficient back-up in place after the power cuts in Auckland yesterday - but has warned that if that inquiry finds better backup systems are required it will contribute to higher power prices. Mr Key said there would need to be an inquiry into what went wrong and the response to that. "We know there was a fire, the question is was there enough redundancy built in there." He said if that inquiry found greater contingency systems were needed, it would have a cost. Vector was a controlled monopoly and its charging and costs were set by the Commerce Commission.
