Period-specific information: Year ended March 2018

Period-specific information Scope of regional gross domestic product Regional GDP estimates for 2000–17 are from National accounts (industry production and investment): Year ended March 2017. We balanced data for this period using a national accounting supply-use framework, where industry unit data is available for industries using the bottom-up methodology. Further industry breakdowns for this period may be available on request. Provisional estimates 2018 Final unit data was unavailable for 2018 provisional estimates. We used available data sources with a regional dimension (such as linked employer-employee data (LEED)) to derive provisional regional GDP estimates for 2018. Because the data sources had lower quality, we have only provided provisional estimates for the region totals. Revisions We incorporated revisions to national industry totals. These revisions affect the national totals that are allocated to regions. See 2018 national accounts improvements preview for more information. We updated regional allocation proportions for 2016 with new input data, which includes updated Annual Enterprise Survey data and LEED. This update affects the proportional allocation to regions, which results in revisions to all regions for 2016. en-NZ
