The university is divided into four academic divisions: 
Division of Humanities
Division of Health Sciences
Division of Sciences
School of Business
For external and marketing purposes, the Division of Commerce is known as the School of Business, as that is the term commonly used for its equivalent in North America.
Historically, there were a number of schools and faculties, which have now been grouped with stand alone departments to form these divisions.

In addition to the usual university disciplines, the University of Otago Medical School (founded 1875) is one of only two medical schools in New Zealand (with component schools in Dunedin, Christchurch and Wellington); and Otago is the only university in the country to offer training in Dentistry.
Other professional schools and faculties not found in all New Zealand universities include Pharmacy, Physical Education, Physiotherapy, Medical Laboratory Science, and Surveying.
It was also home to the School of Mines, until this was transferred to the University of Auckland in 1987.
Theology is also offered, traditionally in conjunction with the School of Ministry, Knox College, and Holy Cross College, Mosgiel.

There are also a number of service divisions including:
External Engagement Division
Financial Services Division
Human Resources Division
Information Technology Services Division
Property Services Division
Research & Enterprise Division
Student Services Division
