Utilities Disputes commissioner Nanette Moreau says she is concerned Kiwis are in the dark about what to do when their power is disconnected.
More than 6,000 homes were disconnected in the last quarter of 2016, due to no payment, but just 41 people of 6170 homes made complaints about being disconnected.
Disclosing hardship to electricity providers is the best way forward, Moreau said.
"If people put the bill in the shoe box or in the bin, it's going to make the situation worse," she said. "Often times, if you as a consumer are vulnerable and you explain to the company that you are in a vulnerable situation, they'll try to work with you to ensure your power stays on.
"One of the difficulties is if you do get disconnected is you have the cost of disconnection and reconnection and it just makes a bad situation even worse."
