Revisions

We have incorporated several revisions to residential and non-residential buildings in this release.

The revisions reflect updated data that impacts historical results. They affect the PPI and CGPI from the March 2011 and March 2006 quarters, respectively, but the higher level indexes (CGPI ‘All Groups’ and PPI Inputs and outputs ‘All Industries’) have not been affected.

These revisions will be incorporated in Gross domestic product: September 2018 quarter (which will have a minor impact on construction activity and gross fixed capital formation) and in Value of building work put in place: September 2018 quarter (which will have a small impact on volumes in some periods).

Exchange rates

The New Zealand dollar depreciated against four key currencies (US dollar, Australian dollar, Japanese yen, and the Euro) and appreciated against the UK pound when comparing the mid-point of the September 2018 and June 2018 quarters. A depreciating NZ dollar has an upward influence on the prices New Zealand producers pay for imported goods and services, and the prices received for exports. When calculating the PPI and CGPI, we generally use prices collected on the 15th day of the middle month in the quarter to represent the entire quarter. When these prices are collected in foreign currencies, they are converted to NZ dollars using the exchange rate at the mid-point of the quarter. The table below shows changes in the value of the NZ dollar in foreign currency denominations, from the mid-point of the June 2018 quarter to the mid-point of the September 2018 quarter.
