Data for the 2021 financial year is provisional.
As the 2021 AES results cover enterprises with balance dates between 1 October 2020 and 30 September 2021, the impact of COVID-19 is varied.
The AES data is to be used with caution below industry design level (NZSIOC level 4). The survey is not designed to support analysis below this level.

Some industries are excluded on statistical grounds due to the difficulty of collecting the data from respondents: superannuation funds (K6330), residential property operators (L6711), foreign government representation (O7552), religious services (S9540), private households employing staff and undifferentiated goods and service-producing activities of households for own use (S960).
Non-market government units have not been included in the AES population for all data published since the AES 2015.

Businesses that are not economically significant are not selected into the AES.

On 1 January 2019 most businesses changed the way they account for leased (‘right-of-use’) assets under the International Financial Reporting Standard 16 (IFRS 16).

The Annual Enterprise Survey (AES) is New Zealand’s most comprehensive source of financial statistics covering around 500,000 businesses. It provides annual information on the financial performance and financial position for industry groups operating in New Zealand. 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.
