A technical fault is causing delays at the Te Ngae Rd/Sala St traffic lights.
Rotorua Lakes Council transport operations manager Peter Dine said a technical fault with the lights at the intersection was currently affecting the sequence timing and was causing delays to traffic at some times of the day.
Contractors undertook repairs yesterday but unfortunately the problem had resurfaced again today, he said.
"The contractors are again working to resolve the problem as quickly as possible.
"As we are uncertain how long it will take to get the signals back to normal we're asking drivers to be patient and exercise care along the route. We appreciate motorists' co-operation and understanding in the meantime."
