New Zealand’s mobile speed camera trailers have faced repeated vandalism during their first year on the roads, with incidents recorded across several regions.
The mobile units were introduced in September 2025 as part of efforts to reduce speeding and improve road safety. Since then, the 10 trailers have been vandalised 18 times, according to figures released by NZ Transport Agency Waka Kotahi under the Official Information Act.
The incidents included graffiti, damage and tampering. One trailer also had a tyre slashed. Despite the attacks, none of the units was damaged beyond repair or permanently taken out of service.
Manawatū-Whanganui Recorded the Most Incidents
The vandalism was reported in several parts of the country.
Manawatū-Whanganui recorded the highest number, with six incidents. Waikato followed with four. Canterbury and the Bay of Plenty each recorded three incidents, while Auckland and Southland each recorded one.
Of the 18 incidents, 11 involved graffiti. Six involved tampering or other damage, while one trailer was spray-painted and had its tyre slashed.
NZTA said the vandalism was disappointing. It also warned that damaging the equipment can create unnecessary costs and potentially put other road users at risk. The incidents were reported to police by Acusensus, the company responsible for operating the mobile cameras.
Cameras Designed to Discourage Speeding
The mobile cameras are intended to do more than identify individual speeding drivers. NZTA says their wider purpose is to discourage people from exceeding speed limits, even when they do not know whether a camera is nearby.
The trailers can be moved between locations based on crash information and community feedback. Their cameras can detect vehicles travelling both towards and away from the unit, with a range of about 300 metres.
The units also have security and tracking equipment, including CCTV and alarms. NZTA monitors them around the clock.
The agency has previously said safety cameras are intended to reduce deaths and serious injuries by encouraging safer speeds. The idea is that drivers become more cautious because cameras can operate in different locations rather than remaining permanently in one place.
Thousands of Drivers Already Detected
The vandalism comes as the mobile camera programme continues to record speeding offences across New Zealand.
In the first six months of operation, more than 73,000 motorists were captured by the mobile trailer cameras. The total value of infringement fees issued during that period exceeded $4.65 million.
NZTA does not receive the money from those infringement fees. The revenue goes into the Government’s Consolidated Fund.
The agency says camera locations are selected using crash data as well as feedback from local communities. The focus is on reducing dangerous speeds and preventing serious crashes rather than simply issuing penalties.
For drivers, the message remains straightforward: following the speed limit is the safest approach, regardless of whether a camera is visible.
