Timaru Medical Centre as it is now, is the result of the merging of 5 General Practices from three different sites in Timaru, into a new purpose built facility. The first merge occurred in July 2017 amalgamating Hassall Street Surgery and the three other practices within Timaru Medical Centre in Harper Street. The second merge occurred a year later with the Better Health team from Elizabeth Street joining the practice. The result is the largest General Practice in South Canterbury with over 10 thousand patients catered for.
