Preference of enrolment is given to students who have established a link with the Catholic Church through baptism or membership of a parish. Preference is decided by your parish priest. A preference certificate from the parish is required for each students with the application for enrolment, when applying to enter the school. Students without preference are welcome to apply but enrolment is restricted by state legislation to 5% of the total roll. Zoning does not apply to the College. The main contributing schools are the parish schools in the city but many students from other state schools join the Kavanagh family each year. Enrolments come from both urban schools and rural schools.
School fees are set by the Dunedin Diocese and for 2015 are:
- $420 for years 7 and 8
- $830 for years 9 to 13
