Entry requirements

A postgraduate diploma can usually be taken at any time after the completion of your bachelor's degree.

If your first language is not English you need to meet our English language requirements as follows: IELTS score of 6.5 in the academic module (with no individual band below 6.0); we also accept a number of other English language tests. Due to COVID-19, we currently accept Duolingo English Test (DET), IELTS Indicator Test, and TOEFL iBT Special home Edition.

Don’t meet the English language requirements? The University of Otago Language Centre English for Otago programme offers a pathway for Undergraduate and Postgraduate students to meet the English language requirements for undergraduate and postgraduate study.

Course content

The Postgraduate Diploma in Science (PGDipSci) is a one-year programme which builds on an undergraduate science degree. The diploma encompasses both papers and a research topic, and can be taken full-time. It provides entry to the Master of Science (MSc) degree by thesis only.

Botany covers all aspects of the life of plants. It therefore includes their structure and development, physiology and biochemistry, health and disease, relationships with other organisms and the environment (ecology), as well as the traditional aspects of plant identification and classification.

The main emphasis at Otago is on the general biology, ecology and physiology of higher plants and marine algae, although other groups (conifers, ferns, mosses and fungi) are also included in the papers offered.
