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.
We have target processing times for all crash reports. These targets relate to the time taken from the date at is the crash report is received by the Transport Agency until the time it is entered in the crash analysis system (CAS).
CAS users can access the system here (external link) .

We have also produced some CAS training videos which are available here (external link) . 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.
