Who has access to your personal information

Some information on crashes is publicly available in the Waka Kotahi Open Data Portal. Users of this portal cannot access your personal information and so cannot identify you at all.

Direct access to CAS may be provided to users who must first sign agreements for access which place obligations on them to only use the data for approved purposes. Examples include engineers who may want to analyse individual crashes to evaluate road safety projects.

Users with direct access are prohibited from disclosing any information that may reveal the identity of any individual involved in a crash.

We can also link CAS data to data from other sources to improve its usefulness to recipients.
