Dear New Zealand Transport Agency,

I am writing to request information under the Official Information Act regarding the mobile speed camera vans and SUVs currently in use across New Zealand, including those being rolled out in May and June 2025.

Specifically, I would like to request the following details:
1. Radar Technology: What radar technology or frequency bands are being used in these mobile units (e.g., K band, Ka band, X band)?
2. Frequency Range: What is the specific frequency range of the technology (e.g., Ka band 24.700–24.750 GHz)?
3. Equipment Manufacturer: What is the brand or manufacturer of the speed detection equipment (e.g., Redflex, Jenoptik, etc.)?
4. Detection Range: What is the typical or average detection range of the equipment (e.g., 200–300 meters)?
5. Operational Mode: Do the radar units operate continuously (i.e., transmitting full-time), or do they use systems such as “instant-on” or other intermittent activation methods?
6. Camera Systems: What type of camera systems are paired with the radar equipment (e.g., license plate recognition, high-definition video)?
7. Evidence Retention: What is the standard evidence retention period for images or data captured by these systems?
8. Additional Deployment Methods: In addition to vans and SUVs, are there current plans—or has consideration been given—to deploy trailers, covert/hidden camera systems, or other less-visible/mobile enforcement methods as part of this rollout?
9. Policy and Purpose: What is the specific operational or policy-driven motive behind introducing this new generation of mobile speed enforcement units? Please provide detail beyond general statements such as “to catch speeders” or “to improve road safety”—for example, is there data showing increased speeding trends, funding priorities, international alignment, or other driving factors?

This information is requested to better understand the operational capabilities, deployment strategy, and policy context for these enforcement tools on New Zealand roads.

If any of this information is withheld under the Act, I would appreciate an explanation of the reasons, as required.

I look forward to your response.

Yours faithfully,
Tyler
