A request per https://www.data.govt.nz/datasetrequest/show/685 As NZTA Crash Analysis System (CAS) still doesn't capture most of the accidents records. An updated accidents dataset for the last 5 years (05/2019 - 05/2024) including Date, Time, Latitude, Longitude, Street/Road Name, Meshblock, Injury Severity Number of injured, On/Off Road, Number of other Vehicles involved, Type of other involved (pedestrian, e-scooter, bicycle, motorbike, car, van, truck, bus, other) would be very useful for analyzing patterns of accidents.

An important use of the CAS data is to identify cyclist accident black spots by specific location (eg. intersection) or by a stretch of road.
This data is used to design and modify road infrastructure for all road users, including cyclists.

If the ACC data related to vehicle crashes (including cyclists) was mapped onto the CAS database in the back end, then all of the front end functionality available through the CAS portal could be used. The combination of CAS data and ACC data would enhance the overall quality of data available to all users.
