You can apply to graduate in absentia, which means you don't have to be present at a graduation ceremony, and your certificate will be posted to you within 5 working days of the ceremony taking place.
You should indicate your decision to graduate in absentia in your application form. Go to your 'Graduation' tab and select 'Apply to graduate'. In the application form, select 'I would like to graduate in absentia'.
Please make sure that your contact address is correct and up to date in MyWaikato BEFORE the date of your graduation if you select to graduate in absentia.
