"While we'd prefer a glass balustrade, if vandalism occurs again we will be forced to replace this with a stainless balustrade."
Replacing the glass panels costs up to $6500 each time they are vandalised.
While uncertain what caused the damage, it is likely to have been a large heavy object being thrown against the glass, according to the spokeswoman.
Napier City Council has set aside $500,000 to replace and expand the city's CCTV network, which is "at the end of its life", as part of NCC's Annual Plan.
"We will be working with police and incorporating data and community feedback on incidents like this to help us determine the best places for camera locations for our expanded CCTV network," the spokeswoman added.
Work to replace the panels is expected to be finished early next week.
Anyone who has seen any suspicious behaviour is asked to contact police.
