EECA's role under the Energy Efficiency and Conservation Act includes assisting the Minister of Energy to prepare and administer a strategy. On 27 September 2001, the first five-year National Energy Efficiency and Conservation Strategy was released.
The New Zealand Energy Efficiency and Conservation Strategy (NZEECS) was written in 2007, and was a key part of the government’s response to meeting its energy, climate change, sustainability and economic transformation goals. It has been written as a companion document to, and will give effect to a number of the objectives set out in, the New Zealand Energy Strategy (NZES).
