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.
