Mr Caffell said when it became known cameras would sweep the square he had been contacted by "law abiding citizens" who felt their privacy could be invaded.
Those people, he said, used the square to sit "and have a cuddle or whatever they do" and felt there was a thin line between what was surveillance and what was intrusion into their lives.
Meanwhile, the council has awarded a contract for upgrading the closed circuit television system at the police station.
Advanced Security Group Ltd secured the contract with the lowest tendered price of $32,285, excluding GST.
Four tenders were received and the price was well inside the council's budget estimate of $45,000 to $55,000.
Two other council contracts have also been let.
The strengthening of Wardells Bridge over the Ruamahanga River was awarded to Concrete Solutions Ltd for $151,717, excluding GST, being the lowest of six tenders and well within the estimate of $234,000, and a contract for kerbing in the urban ward was won by Higgins Contractors Ltd.
Higgins had submitted the lowest of two tenders, being $54,856.
