"We are sick of hearing every time there is a power hike its everybody's fault, everybody's fault but the power generators and retailers," Mr Cunliffe said.
The policy document states power prices for the average household would drop by $230 to $330 a year, businesses would also see prices drop by between five and seven per cent, and the policy was also expected to create 5000 jobs and boost the economy by $450 million per annum.
Mr Bridges said for all of Labour's "bluff and bluster" about power prices, they didn't seem to be in any hurry to do anything about it.
"Despite rehashing and re-announcing their discredited power plan, Labour has backed away from their proposal, delaying its implementation until January, 1 2018 - two elections away.
"The reality is Labour's complex, costly and bureaucratic proposal will kill competition, threaten security of supply, and do nothing to lower power prices. And delaying their proposal will create uncertainty in the electricity market for more than three years," he said.
Tauranga Budget Advisory Service co-ordinator Diane Bruin told the Bay of Plenty Times the policy could benefit hundreds of people in Tauranga.
She said power was the highest cost commodity for many people and some residents did not know how to manage the cost.
