Tauranga residents could save up to $330 a year on their power bill under NZ Power, according to Labour Leader David Cunliffe.
The electricity policy was initially announced a year ago but was rolled out again by Mr Cunliffe while he was on the campaign trail in Rotorua yesterday.
The move has been shot down by Tauranga MP Simon Bridges who said Mr Cunliffe was just rehashing and re-announcing a discredited power plan. "We're recommitting to bringing electricity prices back under control using NZ Power. NZ Power will bulk buy electricity from all the generators and pass the savings on to New Zealanders," Mr Cunliffe said.
"We'll make sure that companies get a fair price for their product but it will be a price linked to how much it costs them to generate that electricity."
Labour's Energising New Zealand policy document states a new agency called NZ Power would act as a single buyer of wholesale electricity and would have the power to set prices based on operating costs and a fair return on capital.
