Modelled Territorial Authority Gross Domestic Product (MTAGDP)

From October 2015, the Ministry of Business, Innovation and Employment annually publishes experimental estimates of MTAGDP.

The rationale is to create a public asset to promote further research and analysis, with the aim of better informing decision-making at various levels of government and by private decision-makers (e.g. investors).

The key motivation for developing the MTAGDP estimates was that there was a lack of consistent, robust, and readily available regional economic data at this level for research and policy development. The ability to distinguish economic production in "urban" versus "rural" areas of a Regional Council needs information at least at the Territorial Authority level. Hitherto this has only been available through commercial providers or customised analyses - which generally lack in consistency, transparency, inter-operability, and the ability to build a cumulative body of analysis.

In order to address this need, MBIE has developed MTAGDP estimates based on publicly available data, including employee numbers and earnings from the Business Demography Statistics (BDS) and the Linked Employer-Employee Database (LEED), and official published Regional and National GDP statistics from Statistics New Zealand. One advantage of producing the MTAGDP is that it provides GDP estimates at a desired level of geographic resolution (i.e. Territorial Authority) and a finer industry breakdown which are consistent with official published sources.

The MTAGDP estimates with industry-level detail are available from the years 2000 to 2015. The current version is based on the Statistics New Zealand Regional GDP product that provides industry-level information to 2014 from balanced national accounts. Industry detail for 2015 and regional totals for 2016 are provisional measures provided by Statistics New Zealand. Similarly, the MTAGDP estimates include provisional industry estimates for 2015 and total GDP at the Territorial Authority level (i.e. no industry-level information) to 2016.

About the MTAGDP estimates

The MTAGDP are derived from a variety of data sources.

Summary documents

The Ministry has produced a series of graphic outputs of MTAGDP measures for individual industries and Territorial Authorities to illustrate industry composition within TAs or the relative ranking of TAs in terms of contribution to GDP for a given industry.

Caveats and disclaimers:

These estimates are at a more detailed level of granularity than available in the Statistics New Zealand official Tier 1 regional GDP series.

They are experimental in nature and should be used with caution. The data are modelled and produced by the Ministry of Business Innovation and Employment (MBIE) (not by Statistics New Zealand), according to the methods outlined in this document.

About the MTAGDP estimates

These estimates are not a Tier 1 statistic and have been created by MBIE for research purposes. While various Statistics New Zealand collections form the source data, Statistics New Zealand will not be held accountable for any error, inaccurate findings or interpretation within the publication.

One of the sources used for the modelling is a customised dataset created in a way that protects confidentiality, provided by Statistics New Zealand. Access to that data was provided to MBIE by Statistics New Zealand under conditions designed to give effect to the security and confidentiality provisions of the Statistics Act 1975.

While all care and diligence has been used in processing, analysing, and extracting data and information for this publication, MBIE gives not warranty it is error free and will not be liable for any loss or damage suffered by the use directly, or indirectly, of the information.
