Traffic Light sensor is placed too closely to the line.
When coming from Puhinui (side where Great South road is) turning right into Carruth Road. The sensor seems to be placed too close to the line. So when cars stop, and leave a 1 metre gap before the line, the light will not go green, untill the car has moved right up to the light. This causes traffic to be backed up when turning left and causes frustrations.
This problem only started after there were roadworks. It seems upon fixing the road, the sensors had been moved futher up.
