Dear Grant
I refer to your Official Information Act 1982 (OIA) request dated 31 October 2025 for
information regarding your infringement notice PV8146395.
You requested:
I request a copy of the certificate of calibration for the equipment allegedly used
and the qualification showing the officer is competent to operate said system
Before you read the below, please note that the alleged offence was captured by a
certified radar device. In short, these devices produce electromagnetic signals to
calculate the speed of a moving vehicle, distinguishing the direction of travel via antennas
located on the front and/or back of the patrol car. When in use, Police officers can
operate the radar while moving or stationary.
Please find enclosed the officer’s notes outlining your vehicle’s tracking history. By
establishing the latter, this provides the operator with assurance that the target vehicle’s
speed is correctly captured through visual observation, audio confirmation, and radar
verification. However, it is worth acknowledging that the notes made at the time are a
condensed version of what occurred and designed to be an aide memoire for the officer
to refer to in the event of a defended court hearing.
Please find enclosed the Certificate of Accuracy for the radar device.
Under section 146 of the Land Transport Act 1998, all operational speed detection
equipment, including safe speed cameras, radars, lasers, and vehicle speedometers are
required to be calibrated annual y. The responsibility for testing and certification rests with
Police Calibration Services, an International Standards Accredited Laboratory, based in
Wel ington.
Please find enclosed the following supporting evidence for your convenience.
• A photograph of the captured speed on the radar device
• The officer’s Certificate of Training

Having careful y reviewed the supporting evidence and taken the above
questions/comments into consideration, it has been determined that the infringement
notice has merit and remains payable. Although you may disagree with my assessment,
you have the right to request a court hearing in which a district court judge wil facilitate
the final decision in accordance with New Zealand law. Alternatively, you may wish to
seek independent legal advice or approach one of the twenty-four Community Law
Centres situated throughout New Zealand:

It should be noted that information requested under the OIA runs separately to the
infringement process timeframe. Therefore, continued correspondence with Police
regarding these matters does not remove your obligation to either request a court hearing
or pay the infringement fee by the final due date.
