Through a process of engagement with staff the number of compulsory changes had been kept to a minimum, the university said.
Sixty-three staff have elected to take early retirement or voluntary redundancy.
These departures had contributed significantly to securing $3.9 million of savings in personnel expenditure, with 89% of this being reached through voluntary means.
There would be a net reduction of 48 full-time-equivalent positions, the university said.
The university received more than 340 submissions from staff, students and external parties on its proposed changes to staffing.
Half of the university's original proposals were altered (either amended or not confirmed) as a result of the submissions.
''This is not a pleasant process for staff, students or the university itself,'' vice-chancellor Andrew West said.
''The professionalism of the staff and the Tertiary Education Union, and understanding of students, during this period is appreciated by the university. I am pleased that we kept compulsory changes to a minimum. We will now work with affected staff around options for their future.''
