Crash Analysis System (CAS) Data

To download the full dataset as a file geodatabase, please go here.This data was extracted from the Transport Agency Crash Analysis System (CAS). It is updated on a quarterly basis. CAS records all traffic crashes as reported to the Transport Agency by the NZ Police. Not all crashes are reported to the NZ Police. The level of reporting increases with the severity of the crash. Due to the nature of non-fatal crashes it is believed that these are under-reported. CAS covers crashes on all New Zealand roadways or places where the public have legal access with a motor vehicle. The Transport Agency's target is to process all fatal crashes within one working day of the crash report being received. This target continues to be achieved. The Transport Agency’s target is to process all injury crashes (serious and minor injury) within four weeks of the crash report being received. For up-to-date information on the current number of outstanding crash reports, please see the Transport Agency website.  We anticipate that the majority of the unprocessed crash reports will be for non-injury crashes. Data is currently available from 1 January 2000 and is updated monthly. The dataset includes crash variables confirmed as non-personal data. While the Transport Agency has taken reasonable care in compiling this information, the information is provided on an ‘as is, where is’ basis and the Transport Agency will not be liable for any action taken on the basis of the information. For further information see the Transport Agency disclaimer . The charts in the Attributes section below provide you with information about each of the attributes (variables) in the dataset. These are to give you a quick overview of the data. Each chart is specific to a variable, and shows all data (without any filters applied). Variables in the dataset are formatted for analytical use. This can result in attribute charts that may not appear meaningful, and are not suitable for broader analysis or use. In addition, some variables are not mutually exclusive and should not be considered in isolation. As such, these charts should not be taken and used directly as analysis of the overall data.A table describing each of the attributes below can be found here.
