EnergyEfficiency and Conservation Authority EECA is a New Zealand government crown agency responsible for promoting energyefficiency and conservation. EECA was set up by the New Zealand Government in 1992 to encourage, support and promote energyefficiency, energy conservation, and the use of renewable sources of energy. In 2000 EECA became a Crown Entity, established under the EnergyEfficiency and Conservation Act 2000 . It is subject to the Crown Entities Act 2004. The passing of the EnergyEfficiency and Conservation Act meant that for the first time, New Zealand had a legislative basis for promoting energyefficiency, energy conservation, and renewable energy. The EnergyEfficiency and Conservation Authority is responsible for preparing a national energyefficiency and conservation strategy for approval by the administering Minister. ref cite web url http www.legislation.govt.nz act public 2000 0014 latest DLM54984.html title Section 13.
