It's not uncommon for winter bills to reach into the hundreds - what can you do about it?
For many New Zealanders power prices are higher than ever, but according to Consumer NZ Chief Executive Sue Chetwin, there is a way to reduce high winter bills.
"Every year New Zealanders spend $280 million more on power than we need to, just by being with the wrong suppliers" said Mrs Chetwin.
Each New Zealand household could save on average $165 per year just by switching to a cheaper power company, and many could save hundreds more.
