Energy Use Survey: Services sector 2010
Embargoed until 10:45am  –  13 October 2011

About the Energy Use Survey

The Energy Use Survey collects and publishes statistics detailing the energy used by three sectors of New Zealand economy – the primary, industrial and trade, and services sectors. Organisations  provide information on how much energy they use, which allows us to publish data at industry and national levels for different energy types. The energy types include electricity, petrol, diesel, coal, natural gas, and renewable energy types.
