UPDATED 3:04pm: Auckland Council is being asked to explain its plans to build a city-wide surveillance network which could have facial recognition technology.
The network of CCTV cameras would be available to police so the could monitor crime, traffic, emergencies, and public safety issues.
But Batch Hales from the Council for Civil Liberties says it's unclear why the city would need it.
He says it presumes everyone is guilty until they're proven innocent.
Spokesman Thomas Beagle says it would be a massive invasion of privacy.
He doesn't agree with automated tracking devices, which he says would have the Government watching your every move.
Auckland Mayor Len Brown is defending plans for the surveillance system being installed in the city.
Mr Brown says alongside tighter rules on alcohol sales, the cameras should help prevent crime and anti-social behaviour.
"This is all about ensuring that experience, particularly in our downtown area and our tourist spots, is safe, they see the very best of New Zealanders, not youngsters off their face."
