Selected Services Survey

Population The target population is all KAUs on Statistics NZ’s BR that are operating in New Zealand and are classified to the following New Zealand Standard Industrial Output Categories (NZSIOCs): MN111 – Scientific, architectural, and engineering services MN112 – Legal and accounting services MN114 – Veterinary and other professional services RS211 – Repair and maintenance RS212 – Personal care, funeral and other services. Methodology changes The series for this survey is produced using GST data wherever possible. We have done extensive work over the last few years on GST data and have established that it is a reliable measure of activity in these industries apart from the largest and most complex businesses. We have developed robust methods of transforming the data, which is submitted at different frequencies, to a quarterly frequency. In addition, we have developed methods of detecting and removing sales and purchases of large capital items, which can at times occur in the GST data. These are not part of the conceptual measure of sales required for national accounts purposes. We supplement the GST data for each of the series with survey data for large and complex businesses which meet the following criteria: A $100 million significance rule – if an enterprise, or group of enterprises linked by ownership, have an annual GST turnover of more than $100 million. A 3 percent industry dominance rule – if an enterprise makes more than a 3 percent contribution to annual total income for an industry. All enterprises that have a significant level of activity across multiple industries. Seasonal adjustment Seasonally adjusted and trend series have been produced using the X-13ARIMA-SEATS package developed by the U.S. Census Bureau. As we have maintained the previously published industry movements for manufacturing and wholesale trade data there is minimal change to the seasonally adjusted movements over time. en-NZ
