Known gaps
- Recent months are incomplete: crash reports reach CAS weeks or months after the event, and severities can be updated after investigation. The latest year is partial.
- 2020 and 2021 counts are affected by COVID-19 lockdowns and travel restrictions, and NZTA has noted that some crash reporting in this period is incomplete. Compare these years with care.
- CAS contains crashes reported to NZ Police. Crashes not reported to Police, and many non-injury crashes, are not included.
Update schedule
NZTA updates the open data monthly. This site is rebuilt from a complete fresh download; each rebuild checks the record count against the publisher’s count before anything changes.
