Seasonal adjustment

New items of income or expenditure that are included by local authorities can impact seasonal adjustment when the seasonal component of the data is unknown. With the introduction of Auckland’s regional fuel tax (RFT) in the September 2018 quarter, we have seen greater volatility in the seasonally adjusted regulatory income and petrol tax series. We expect this volatility to continue for a number of quarters until we have collected sufficient data to understand any changes in the seasonality of this series resulting from the introduction of the RFT.

In September 2019 a review of all series was carried out. Based on the review, several changes to seasonal adjustment were implemented in the September 2019 quarter: the rates series is now seasonally adjusted, while the interest received and interest paid series are no longer seasonally adjusted.

In June 2020, the seasonal adjustment series were reviewed and additive outlier adjustments were applied to account for the impacts of COVID-19 to the following series:

  • Regulatory income and petrol tax
  • Sales and other operating income
  • Total operating income
  • Purchases and other operating expenditure


Annual benchmarking to Local authority financial statistics data

Local authority financial statistics (LAFS) is an annual collection which covers local authorities’ income and expenditure. Each June quarter, we reconcile recent provisional quarterly Local Authority Statistics data with the latest available LAFS data to enhance the accuracy of the Local Authority Statistics collection. In the June 2020 quarter, this involved reconciling September 2017 to June 2019 quarters to annual LAFS data for the year ended June 2019. As such, various revisions were applied this quarter, as expected at each June quarter release.

With the introduction of Regional Facilities Auckland Trust to the LAFS collection for year ended June 2019, the annual benchmarking to LAFS has resulted in revisions to the quarterly local authority statistics collection from 2011 onward, when the Regional Facilities Auckland Trust was first established.
