Enterprise: a business operating in New Zealand. It can be a legally constituted body, such as a company, trust, local or central government trading organisation, an incorporated society, or self-employed individual.
Exports: goods and services sold overseas by a New Zealand company. This excludes goods sold to other New Zealand businesses who will export the goods at a later stage.
Goods and services pricing: the data reported from the ICT Supply Survey is collected and reported in nominal dollar values at time of sale. These nominal sales figures combine price and volume movements. Price movements of these goods and services may disguise the volume or quantity change in goods and services sold.
The ICT Supply Survey measures the sale of goods and services from businesses associated with ICT industries. The ICT Supply Survey replaced the Information Technology Survey (1993–2004).
The OECD defines ICT goods and services as those that fulfil or enable the function of information processing and communication by electronic means. Alternatively, ICT goods may also use electronic processing to detect, measure, and/or record physical phenomena, or control a physical process.
