Types of fuels used by the heavy and civil engineering construction industry in New Zealand

Calorific value: The energy contained in a fuel, determined by measuring the heat produced by the complete combustion of a specified quantity of the fuel. Statistics NZ converted all the different energy types into terajoules (TJ) to make them easily comparable.
Enterprise: A unit or business entity operating in New Zealand. It can be a company, partnership, trust, estate, incorporated society, producer board, local or central government organisation, voluntary organisation, or self-employed individual.
Joule (J): A unit for measuring energy. The main unit we use in this release is the terajoule (TJ). One terajoule is approximately equal to the total electricity used by 35 households in one year.

From 2016, the year in the release title reflects the year in which the survey was run.
This is a change from previous years. For example, when the survey was run in 2015, the data was published as 2014 data.
Therefore there is no gap in the annual series.

At URL provided, select 'Industry sectors > Energy Use Survey - EUS > Energy use type by Industry in Terajoules (Annual-May)'. All variables were selected to create this dataset.

This survey is used to collect statistics about the energy used by all types of New Zealand businesses, in the primary, industrial, trade, and services sectors. Organisations provide information on how much energy they use, which allows Stats NZ 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.

The survey was posted out in April each year, with a reference period of the last financial year for which the business had results available in May.
The Energy Use Survey has been designed as a rolling survey: different industry groupings (ANZSIC06) are surveyed every year, with the objective that the whole economy is covered in three years.
