Turning drivers were not giving way to pedestrians crossing on a green light, she said.
"The police are aware of it and they try to manage it but it's very tricky. You really have to be there at the time."
Some drivers did not realise that when the red man was blinking, pedestrians still had a right to cross, she said.
One of the worst intersections was Glasgow St and Victoria Ave, because of the high volume of traffic travelling to surrounding supermarkets.
A high percentage of elderly inner-city residents, who either walked or used mobility scooters, used that area a lot, she said.
Drivers were also risking fines by stopping on the advance stop box green painted area set up for cyclists at the Victoria Ave and Dublin St intersection.
Nationwide, red light running was the most common traffic light-related infringement, with 10,898 infringement notices issued in 2012 alone, although that had decreased from 15,037 in 2010.
Men were up to three times more likely to commit a traffic-light related offence, with the highest number of offenders in the 31-50 age bracket. Police national road policing manager Superintendent Carey Griffiths said the data had not yet been analysed in depth to determine possible factors regarding the national decline in yearly infringements or in relation to the differing trends by gender or age.
AA Motoring Affairs general manager Mike Noon said feedback from members and the public showed they were "heartily sick and extremely unhappy" with people running red lights.
"If you're a motorist and you see someone running a red light you think 'that could be me coming the other way'," he said.
"We've got a habit in New Zealand which is the amber light means stamp on the accelerator."
It was safe to say men were more likely to be involved in road crashes, he said.
"It is often said of New Zealand compared to other countries that we have quite an aggressive driving style and we're not as courteous as we could be."
