New technology being rolled out by Auckland Transport in an effort to ensure bus lane compliance has been labelled "overkill" - but the agency says it'll help keep people and freight moving around the country's biggest city. Onewa Road in the North Shore suburbs of Birkenhead and Northcote is set to get 68 new cameras to check cars have at least three people in them if they want to use the bus lanes during rush hour. The 2.3km stretch of road is used by 42,000 vehicles a day as it's a motorway access point. From May, the new CCTV network which will look into a car from the front and the side will monitor for compliance and send any breaches to an officer for review. Kathryn talks to KaipÄtiki local board chair John Gillon about the complaints he's been fielding from residents, and Auckland Transport's Parking Compliance Manager Rick Bidgood about why the technology is necessary and how it will be rolled out more widely.
