Households can slash the amount they spend on electricity, say experts.
Most households could easily cut their power bills by 10 per cent by making small adjustments, energy conservation experts say.
Power prices have been in the news this week as Energy and Resources Minister Simon Bridges estimated bills would rise an average 2.4 per cent this year and Genesis and Meridian stated their customers could face 3.6 per cent increases.
But Christian Hoerning, of the Energy Efficiency and Conservation Authority (EECA), said most households could make a difference to their bills easily.
Space and water heating were the two biggest users of electricity, Hoerning said, using two-thirds of the house's power consumption. Lighting and other appliances use the remaining third. He said people should check shower water flow by seeing how fast it fills a 10L bucket.
