Background Information

New Zealand Standard Industry Output Categories (NZSIOC)


The high-level structure of ANZSIC 2006 (that is, divisions and subdivisions) was constructed to align with the top level of the International Standard Industrial Classification of all Economic Activities (ISIC) Revision 4. However, this level of aggregation does not always mirror the New Zealand economy. For example, because of the significance of agriculture and its downstream industries, users require more information about agriculture and primary food product manufacturing than what is provided at the ANZSIC group level. As a result, Statistics New Zealand developed the New Zealand Standard Industry Output Categories (NZSIOC) using the principles used to derive ANZSIC categories – organisation of units, industry homogeneity and economic significance – but adapted specifically to the New Zealand situation. To maintain consistency with ANZSIC and ISIC, the ANZSIC ordering and structure has not been broken unless absolutely necessary.

The NZSIOC will be progressively adopted for all Statistics New Zealand outputs which provide industry statistics. This will ensure coherence and assist users in comparing statistics from different surveys and publications.

Like ANZSIC 2006, the NZSIOC classification fits together hierarchically and consists of four levels:

Level 1

High-level aggregation is intended for use in one-page summary statistics. This level also supports a high-level overview of the entire economy. There are 16 categories at this level. They match with the ANZSIC division level, except for three categories which combine two divisions together.

Level 2

The desired standard minimum level for quarterly statistics (such as the Quarterly Gross Domestic Product (GDP) and a range of supporting statistics). There are 31 categories at this level that generally match with the ANZSIC division level, except that agriculture and manufacturing are split in ANZSIC subdivisions or combinations of subdivisions to reflect the importance of agriculture and primary food product manufacturing in the New Zealand economy. Local government administration is split out from Division O Public Administration and Safety to support the widespread interest in the local government activity.

Level 3

The desired standard for annual statistics. The annual National Accounts and the Annual Enterprise Survey will be published at this level. Supporting series of wage and price indexes should also be available for most of these categories. There are 55 categories at this level. This level generally matches an ANZSIC subdivision or consists of several smaller subdivisions combined together. Subdivisions 01 Agriculture and 11 Food Product Mmanufacturing, are broken down further to better reflect their importance in the New Zealand economy.

Level 4

Working industries. This is the level at which the National Accounts are compiled and analysed. The Annual Enterprise Survey is designed at this level. There are 118 working industries.

There are likely to be some exceptions. Some categories may be aggregated in cases where data quality will not support the level 2 or 3 breakdowns or to protect respondent confidentiality where one or two large firms dominate the industry.
