Waka Kotahi NZ Transport Agency is committed to help plan for and improve road safety in New Zealand. For us to do that, and support others in the transport sector to do that, we provide access to important road safety information, data and tools.
The information helps us, and others, target, fund and measure the effectiveness of road safety initiatives. It provides the evidence base for making good decisions around effective road safety regulation.
Crash Analysis System (CAS) data
We have revised the information we make available from the Crash Analysis System (CAS) on our website to ensure we are appropriately protecting personal information. We are continuing to explore ways we can maximise the information from this system that is publicly available, while ensuring privacy is protected.
We would love to hear from you about how you use this information, and how else we might be able to meet your data needs. Please contact us at email@example.com.
You can download crash information from this website. Please see the spreadsheet in the information and tools section below.
You are also able to apply for free access to CAS for the following purposes:
- Informing transport policy and regulations.
- Designing and prioritising a range of network user behaviour and road safety initiatives.
- Supporting funding applications for network and road safety improvements.
- Monitoring and evaluating the effectiveness of road safety initiatives.
- Providing information for research purposes connected with road network user behaviour, road safety and transport policy.

- Crash Analysis System (CAS) — New Zealand’s primary tool for capturing information on where, when and how road crashes occur.
- Grouped crash sites — includes information on locations with four or more crashes over a three year time period.
- Aggregated crash data [XLSX, 371 KB] — includes information on deaths and serious injuries by sex, age and vehicle type and by region. It also provides injury counts from fatal and serious crashes and crash counts by crash severity.
- Road safety action planning tool [XLS, 4.7 MB] — includes information drawn from various tools and used to help plan road safety interventions that are targeted to risk.
- Road safety wizard [XLS, 6.5 MB] — includes comprehensive fatal and serious injury crash data from the past five years. Used to understand the circumstances surrounding crashes such as weather conditions, road type, contributory factors (for example, alcohol) and location. This tool provides regional information — down to suburb level. For help with the Road Safety Wizard, you can download this guide [PDF, 1.2 MB].
Responses to parliamentary questions based on CAS data
Parliamentary questions, both oral (OPQs) and written (WPQs), are formal questions posed by MPs to Ministers. In response to Parliamentary questions, the Minister and Associate Minister of Transport often draw on data held by the Transport Agency.
