Request:
Can you please supply data around the causes of fatal and non-fatal accidents for the
2023 calendar year.
This could be summarised, e.g. numbers caused by excessive speed, driver error etc.
If you could deliver this information in an Excel spreadsheet, that would be very
helpful.
You've supplied this previously for the 2019 year; the same format but with updated
data would be perfect.

Please note the fol owing concerning the data contained in this spreadsheet:
• This data is provided from the road traffic crash database; Crash Analysis System (CAS) version 2.6.2
• NZ Transport Agency Waka Kotahi (NZTA) maintains the Crash Analysis System which is updated once a
Traffic Crash Report (TCR) is received from NZ Police sometime after the crash.
• Data is for all crashes in 2023 as recorded in CAS to date - 7/02/2024.
• A crash, to be recorded in CAS must have occurred on a road. The CAS definition of a road is any
INFORMATION street,
motorway or beach, or a place to which the public have access with a motor vehicle, whether as of right or
not e.g. a public car park.
• The cause of a crash cannot necessarily be attributed to any one factor (eg fatigue) as a crash may have
multiple factors.
• Factors are counted once against a crash - i.e. two fatigued drivers count as one fatigue crash factor.
• Due to the police reporting time frame and subsequent data processing there is a lag from the time of a
crash to full and correct crash records within CAS.
• Fatal crash report data is usually recorded in CAS within one working day of NZTA receiving it from NZ
Police. Serious Injury and Minor injury crash report data is usually recorded in CAS within 4 weeks. Data
relating to non-injury crashes may take up to 7 months before it appears in CAS.
• 2023 data is not yet complete in CAS but these are the current figures from CAS as at 7/02/2024.

Factors are counted once against a crash - i.e. two fatigued drivers count as one fatigue crash factor.
The numbers under the headings are the number of crashes where that factor was a contributing factor to the crashes
of that severity. The Total is the sum of all the factors contributing to crashes.
Because a crash may have multiple factors there wil be more total factors than crashes resulting in factors totalling
more than 100% of all crashes
