ANZ Truckometer

The ANZ Truckometer is a set of two economic indicators derived using traffic volume data from around the country. Traffic flows are a real time and real-world proxy for economic activity - particularly for the New Zealand economy, where a large proportion of freight is moved by road. It represents an extremely timely barometer of economic momentum. The ANZ Heavy Traffic Index shows a strong contemporaneous relationship to GDP, while the ANZ Light Traffic Index has a six month lead on activity as measured by GDP. Using statistical techniques we optimise the ANZ Truckometer indexes to map to quarterly GDP growth.
