excess: Driving offences in New Zealand

Description Usage Format Details Source See Also


A dataset containing speeding offences and fines by excess-speed band, in New Zealand between 2009 and 2017.




A data frame with 16307 rows and 6 variables:


Number of offences, value of fines in New Zealand dollars, or number of observations


Officer/Camera-issued and offence/fine


Police district


Police area (subdivision of district)


Speed in km/h over the limit (the limit is not given)


Month of the event


General notes and caveats by the New Zealand Police:

This data contains provisional data which is drawn from a dynamic operational database. This is subject to change as new information is recorded or recoded.

During entry, a small number of infringements were coded to an incorrect Police Area (e.g., there are a small number of red light offences showing in Wairarapa Area where there are no traffic lights).

The data does not include cancelled infringements and proceedings, but does include minor infringements cleared as Written Traffic Warnings (WTWs) since the adoption of Police's Written Traffic Warning Policy in 2014. As WTWs do not have a fee these are not included in monetary value tables.

Most speed cameras employ radar technology to detect speeding vehicles. The process of issuing a speed camera notice involves verification of the resulting vehicle photo to validate the detection. When counting all vehicles passing speed cameras (i.e., all moving vehicles complying with the speed limit and otherwise), a small number of detections may involve other causes. These cannot be reliably excluded from the total number of detected vehicles as Police record speed camera notice details separately from raw vehicle counts. The total number of vehicles detected by speed cameras on deployment may therefore include a small number of false radar detections. Note also that this data starts from August 2009 as there were some technical issues affecting the rollout of digital mobile cameras primarily between January and July 2009.
