Staff at the medical centre said a change in time limits for the carpark from three hours to all day parking had compromised patients' ability to access services.
More than 150 people signed a petition calling for the council to implement a few time-monitored parking spots.
The council's parking contractors, Environmental Northland, carried out a survey which confirmed the occupancy rates of the carpark in the morning period were 100 per cent and over 90 per cent in the afternoon.
Discussions with some of the surrounding businesses resulted in requests for time restrictions, as opposed to increasing fees only. But in line with its parking policy, the council believed the increase in the parking fee would be enough to bring down the occupancy rate.
To achieve the 70-80 per cent occupancy rate, it has brought the Old Town Hall carpark in line with charges at Forum North, Water St and Laurie Hall carparks.
