Business studies, often simply called business, is a field of study that deals with the principles of business, management, and economics. It combines elements of accountancy, finance, marketing, organizational studies, human resource management, and operations.

The Diploma in Business Studies is taught at Massey University at the Manawatū, Auckland and Wellington campuses. Courses may also be taken via distance learning. The tuition fee is estimated upon national currency and therefore, is subject to change. Moreover, it may also vary due to individual courses a student enrolls in.
