Auckland Transport denies using facial recognition equipment on its CCTV system.
The agency says within five years, they'll have a maximum of 6000 cameras, 600 more than now.
Privacy foundation deputy chair Gehan Gunasekara told Heather du Plessis-Allan he is worried about the cameras having facial recognition.
He says cameras serve a useful function, but has concerns the cameras having facial recognition.
"I have some reservations when I hear there will be a network which is connect to other camera operators and perhaps private companies as well."
But AT spokesman Mark Hannan says there are no plans to introduce this, they haven't done any trials and don't plan to.
He says many of the new CCTV cameras will be around the new underground stations.
