Data Collection
Annual Enterprise Survey 2014
The Annual Enterprise Survey (AES) 2013/2014 collection provides statistics on the financial performance and financial position of New Zealand businesses, covering most areas of economic activity. The AES was designed as the principal collection vehicle of data used in the compilation of New Zealand's national accounts. Data used in this survey is compiled from a number of sources and measures industry levels for a given year. Incremental improvements in measurement, sample design, classification, and data collection may influence the inter-period movements, particularly over longer time periods.

Methodology
Family trusts move to household sector in financial assets investing
In 2014, the AES introduced the Statistical Classification for Institutional Sectors (SCIS) for the first time . Because of this change, family trusts are now classified under the household sector. Before 2014 they were classified under the non-financial business sector.
The AES does not measure household sector activities. As a result, over 10,000 family trusts included in the scope of the AES in 2013 are excluded in 2014. The impacts of the change can be seen in the financial position of the financial asset investors industry (NZSIOC KK112) for the 2014 financial year, particularly in the decrease in fixed asset holdings measured by the AES.
en-NZStatistical Unit
A statistical unit is the level at which the survey is designed and forms the basis of sample selection. For the AES this is the kind-of-activity unit (KAU). (Definition of 'KAU' is a subdivision of an enterprise consisting of a set of one or more activity units for which a single set of accounting records are available.)
Selection Unit
A selection unit is the level at which a respondent to the survey is selected. For the AES this is the enterprise unit. (Definition of 'enterprise': a business or service entity operating in New Zealand. It can be a company, partnership, trust, estate, incorporated society, producer board, voluntary organisation or self-employed individual.)
Collection Unit
A collection unit is the level at which statistics are collected. For the AES, this is the same as the statistical unit and is the kind-of-activity unit (KAU). The selection unit (enterprise) may contain many KAUs, meaning that if an enterprise is selected then all of its KAUs will be included in the AES.
Under Coverage
Businesses that are not economically significant are not selected into the AES.
The working definition for 'economic significance' is that if an enterprise fulfils any one of the following conditions, then it is classified as economically significant:
- The Enterprise has greater than $30,000 Annual GST expenses or sales. (To avoid existing enterprises repeatedly changing their economic significance indicator, a buffer zone of $25,000 to $35,000 has been established),
- The Enterprise has more than 3 paid employees (This is the rolling mean employment which is measured as the twelve month moving average of the monthly employee-count figure),
- The Enterprise is in a GST exempt industry, other than residential property leasing and rental,
- The Enterprise is part of a Business Frame (BF) group,
- The Enterprise is a new GST registration and has registered for Salaries and Wages PAYE,
- The Enterprise is a new GST registration and is part of a IRD GST group return,
- The Enterprise has a geographic unit classified to agriculture, it is alive on the BF, and it is classified as economically significant. (Typically these units will be registered for GST and/or have paid employees.)
- IR10 income is greater than $40,000 annually.
