Council transport operations manager Peter Dine said the replacement and upgrade programme for the cameras was previously budgeted for.
He said they were installed in several spots across the central city and beyond and at a number of council facilities. However, he did not want to disclose exact locations for security reasons.
Work to install the replacement cameras is nearly finished and the three new cameras and some system work will be finished during the coming weeks.
Mr Dine said the old cameras were nearing the end of their lives.
"The old cameras have reached the stage where they are now less reliable and prone to breakdowns, requiring costly repairs. The new cameras are the latest technology available, are much more stable in all types of conditions, have better zoom capability and offer higher quality image resolution."
The cameras are monitored by City Safe Guardians and have recording capabilities.
Block champion and inner-city retailer Ron Finn said improved and increased surveillance "has got to be a positive".
"Not just for retailers but customers and the general public too. Having new cameras and more of them will only make the inner city safer."
Detective Senior Sergeant Zane Smith, who leads the Rotorua CIB team, said the cameras were often used when investigating serious crimes such as robberies and assaults.
The new cameras follow news reported this week 18 new Transport Agency cameras are being installed at traffic light intersections on state highways. Five are already in place at Fenton and Hinemoa Sts, Fairy Springs, Lake and Clayton Rds, Old Taupo and Sunset Rds, Old Taupo Rd and Pukuatua St and Old Taupo and Malfroy Rds.
The cameras are linked to the Tauranga Traffic Operations Centre as well as the council and will be used by the Transport Agency to monitor traffic flow, allowing them to change traffic light sequencing at the touch of a button.
