These crash data [CSV, 63 MB] are presented in a comma separated value ‘.csv’ file to enable open use. These files replace the .csv files that were removed from our website while we ensured we are appropriately protecting personal information.

The dataset includes only crash variables confirmed as non-personal data. We are looking at what additional variables can be added to this file while still protecting personal information. We will alert you to any updates to this file on this webpage.

Data is currently available from 2000 – end of June 2017, and will be updated quarterly.

Our target is to process all fatal crashes within one working day of the crash report being received. This target continues to be achieved. Our target is to process all injury crashes (serious and minor injury) within four weeks of the crash report being received. While there have been some processing delays over the last few months, resourcing has been increased and we are now achieving this target. We expect to continue to achieve this target, and will provide an update here if this changes significantly.

However, we have approximately 22,000 un-processed crash reports. We anticipate that most of these will be non-injury crashes and will therefore not impact on this disaggregated data file, but any injury crashes incorrectly classified initially will not be identified as such until the crash is processed. We therefore recommend that some care is taken when using these numbers.

Information about the variables contained in this data can be found in the file Disaggregated crash metadata [CSV, 12 KB].

The data in the .csv file were extracted from the Transport Agency Crash Analysis System (CAS). CAS records all traffic crashes as reported to the Transport Agency by the NZ Police. Information in these files relate to fatal, serious injury, and minor injury crashes. Non-injury crashes are not included. Not all crashes are reported to the NZ Police. Due to the nature of non-fatal crashes it is believed that these are under-reported. The level of reporting increases with the severity of the crash.

CAS data covers all New Zealand roadways or places where the public have legal access with a motor vehicle.
