The Tauranga Boys' College Old Boys' Association is the driving force behind strengthening and reconnecting the relationships between past pupils and the college.

The association supports initiatives within the college to enhance the quality of education, student leadership, and extra-curricular activities. It also provides financial assistance for students who might otherwise not be able to fully take part in the opportunities on offer at Tauranga Boys’ College. 

Without the support of parents, old boys and friends of the college many of the essential projects and facilities the college has would not have been possible.
