The NZ Transport Agency manages the Crash Analysis System (CAS) - New Zealand’s primary tool for capturing information on where, when and how road crashes occur.
The system provides tools to analyse and map crashes and enables users to identify high-risk locations and monitor trends and crash sites. This information helps inform transport policy, design and prioritise road safety improvements and monitor their effectiveness.
CAS is used by a range of organisations all with the broad aim of improving road safety. It is an essential tool in supporting Safer Journeys and its vision of a ‘safe road system increasingly free of death and serious injury’. It enables the transport sector, over the long term, to improve road safety through knowledge, research and the measurements of the effects of changes to the network and network user behaviour.
Over the last few years the NZ Transport Agency, NZ Police and the Ministry of Transport have been working to improve how road crash information is recorded, processed and then provided to the road safety community.
There have already been some changes. The NZ Police now submit crash information electronically via iPhones. The Transport Agency is maximising this data by improving and modernising CAS through a replacement project.
The road safety community needs quality, reliable and timely information to support its road safety objectives.
A new Crash Analysis System will provide:

We have target processing times for all crash reports. These targets relate to the time taken from the date that the crash report is received by The Transport Agency until the time it is entered in the CAS.
Approved CASE users can access the system (external link) .
Direct access to the CAS system is only permitted for the follow purposes:

We have also produced some CAS training videos which are available here. They will help you log in, extract data, create reports and use other tools available in CAS.
Information and tools to support road safety are available here.
