Producers Price Index quality improvement – 12 February 2009
An improvement has been made to the way the Producers Price Index (PPI) is compiled. The change, which relates to crude oil, affects the inputs index for the wholesale trade industry.
Crude oil is an important input to the wholesale trade industry. Movements in the import price index for crude oil are used in the PPI. Since 2003, these movements have been lagged by one quarter. For example, the movement for crude oil for the June 2008 quarter was used for the September 2008 quarter PPI.
Improvements made to Statistics New Zealand's index compilation practices mean that it is now possible to include the import price index provisional movement for crude oil in the PPI without a lag. Given the recent volatility of crude oil prices, it was important to remove the lag at the earliest opportunity. However, removing the lag for the December 2008 quarter PPI without revising the time series would have caused significant disruption to the latest quarterly and annual movements. Therefore, the time series have been revised back to the September 2003 quarter (when the lag was introduced).
The PPI outputs indexes are not affected by this change. The PPI inputs time series affected are:
- wholesale trade
- all industries, excluding administration, health and education
- all industries.
The Producers Price Index, Inputs (Excel, 34.5KB) table gives the originally published and revised index numbers, quarterly percentage changes and annual percentage changes from the September 2003 quarter to the September 2008 quarter. The revised index numbers are also available on Infoshare (under Economic indicators, Producers Price Index).
The December 2008 quarter PPI information release will be published on 16 February 2009.
Changes to the Farm Expenses Price Index – 17 December 2008
From the June 2004 quarter, the Farm Expenses Price Index tables have been included in the Producers Price Index Hot Off The Press information releases. The format and information in the tables have remained the same.
In August 2008, Statistics New Zealand advised that the Farm Expenses Price Index would be produced for one quarter each year instead of quarterly. This change is due to reprioritisation of some parts of Statistics NZ’s output programme. In November 2008, Statistics NZ advised that the Farm Expenses Price Index would be produced for the March quarter of each year only.
As of 17 December 2008, the Farm Expenses Price Index series for input types that feed directly into the Producers Price Index (Inputs) is available on a quarterly basis from Infoshare and INFOS. The overall Farm Expenses Price Index and input types that do not feed into the Producers Price Index will be produced for the March quarter of each year only.
The input types that will now be available quarterly (for all farms combined and for the individual farm types) are:
- Administration
- Animal health and breeding
- Dairy shed expenses
- Electricity
- Feed, grazing, cultivation and harvesting
- Fertiliser, lime and seeds
- Freight
- Fuel
- Insurance premiums
- Rent and hire
- Repairs, maintenance and motor vehicle repairs
- Packaging costs
- Shearing
- Weed and pest control
- Sub-total excluding livestock
- Livestock purchases
- Sub-total including livestock.
