A University of Otago "Statement of Completed Qualifications" includes your full name and lists each qualification you have completed at Otago along with the date/s those qualifications were completed or conferred (as appropriate).
If you obtain this statement after applying to graduate but before your ceremony takes place, it will note the date on which the qualification is to be conferred. It also states that English is the standard language of instruction at the University of Otago.
You can download a statement of your completed qualifications via a link in the Programmes and papers section of your eVision portal.
Alternatively, you can obtain your academic transcript through My eQuals.
