The Annual Enterprise Survey (AES) 2011/2012 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.




Effect of the 2010/11 Canterbury and Christchurch earthquakes on 2011 and 2012 data

Large earthquakes occurred in Canterbury and Christchurch in September 2010 and February 2011. These earthquakes and their aftershocks had a significant influence on the ongoing economic output of businesses located in Christchurch. We saw continuing financial effects of these earthquakes in the 2012 financial results for the central government and the general insurance industries as claims continue to be settled. We are likely to see payments affecting these industries in future years.

Use of Charities Commission data in 2012

To continue to reduce respondent load, in the 2012 financial year the AES sourced more data from the Charities Commission. In 2012, we sourced 1,849 units from the Charities Commission, compared with 1,519 in 2011. We first used Charities Commission data in 2011.

Use of administrative data and its effect on published variables

Our main administrative data source (Inland Revenue's IR10) is the primary source for capturing the agriculture, forestry, and fishing division (ANZSIC06 division A) in the AES. In 2012 we used more administrative data for other industries as well. IR10 data does not provide direct estimates of additions and disposals of fixed assets, so we use modelling to calculate these. The modelling of IR10 data is currently under review, so additions and disposals of fixed assets have been suppressed from the 'all industries' table, all agricultural industries, and the accommodation industry tables in this release. Our increased use of administrative data in 2012 has also caused discontinuity in shareholders' funds and owners' equity in the repairs and maintenance industry, and the accommodation industry.

Changes in depreciation legislation

On 1 April 2011 a new tax law was introduced that affected depreciation of buildings. This changed the depreciation rate to zero percent for most buildings with an expected life of 50 years or more. The effect of the law change is primarily seen in this release in the rental, hiring, and real estate services industry, which had a very strong $983 million (37.4 percent) decrease in depreciation in 2012. It was also the main contributor to the decrease in depreciation across all industries in the 2012 financial period (down $1,284 million or 5.9 percent).

Sampling Procedure

Statistical 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, local or central government organisation, 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.
