Transport Costs Index (Ongoing)
After consultation with government agencies, the AA Research Foundation (AARF) decided that it would be useful to create an index of household transport costs from 2009 onwards.
Introduction
The aim has been to provide a quarterly view of the effects of price changes on the travelling public. The information is more comprehensive than data that was previously available. It shows public responses to fuel cost changes, insurance cost changes, and changes to government fees and charges.
While the development phase of this project is now complete, Statistics NZ continues to publish updated reports based on this index.
Research Provider
- The AA engaged Stats NZ to deliver this project
Project Manager
- Peter King – AA Motoring Affairs
Research Method
Stats NZ developed six household transport price indexes at the request of the New Zealand Automobile Association (AA):
- General driving costs (North Island)
- General driving costs (South Island)
- Metro commuter (Auckland and Wellington)
- Urban Public transport commuter (Auckland and Wellington)
- Non-urban Public transport commuter (Not Auckland and Wellington)
- Cycling
The indexes were developed with input from the AA to represent 6 different transport profiles.
Stats NZ has used data from the Household Economic Survey - expenditure (HES), Census (2013), and the Consumers Price Index (CPI) to work out the weights (proportion) and associated transport costs for each index.
A back series has been calculated, going back to the June 2008 quarter. Weights for the back series were derived from a mixture of HES and CPI data.
