"We're recommitting to bringing electricity prices back under control using New Zealand power."
Mr Cunliffe said they wanted to also stop the rorting of mainly low income earners who were using pre-pay power metres who were paying up to 60 per cent more than users of regular meters.
"We want to launch an investigation for the cost of pre pay to be bought down to standard rate," he said.
"In terms of the bigger picture Labour is commited that 90 per cent of electricity is generated from renewables by 2025, renewables like geothermal, it's good that we're in Rotorua today to make that statement."
Mr Cunliffe said too many carbon emissions were created by the generation of electricity.
"By increasing renewables we can help the transition to a smarter low-carbon economy.
That's a move that is critical to the clean green brand we trade on overseas. Labour has a vision for a future in which our environment and our economy can thrive and prosper, and in which all New Zealanders share the gains."
