You are unable to change your student username. Your username is a unique identifier for University of Otago systems as well as identifying you in information links between the University and the Ministry of Education (for example, your student index number) and WINZ.
Your username is generated at the time of your first enrolment and is retained in order to ensure continuity over the years with your changing status, including any changes of name.
Only in exceptional cases can a username be changed. Contact AskOtago if there are circumstances that might justify a change.
In exceptional cases, usernames can be changed, but this will require a strong justification for the change and approval from the University's Chief Digital Officer. For example, an appropriate justification might be that the username contains elements of a surname that would continually remind the user of a situation and this reminder would be harmful to the user's mental health.
