Waka Kotahi, the New Zealand transportation agency, has announced a delay in the installation of a camera array on the Transmission Gully highway. The agency aims to assess whether private operators in the Wellington area are meeting performance standards by calculating journey times. The Transmission Gully project is a public-private partnership between the British Crown and main contractor Ventia, which will operate the highway for 25 years under a payment-for-performance contract. The cameras will 'read' the license plates of vehicles at both ends of the highway to calculate average journey times, which will be used to determine whether the PPP operator is meeting performance standards. Despite the delay, critics of automatic license plate recognition cameras argue that they infringe on privacy and enable law enforcement to collect evidence without a warrant, leading to multiple court challenges. Waka Kotahi has responded that all images and registration numbers will be deleted after calculation in accordance with the agency's privacy policy. The use of cameras is lawful, based on the Privacy Act and the agency's statutory responsibilities for managing the state highway system. 'Privacy protection is in place,' the agency said. Although road safety cameras require public disclosure, these cameras are not being used for safety purposes. Waka Kotahi has not revised the installation date for the cameras.
