Not sure if you're interviewing in Suva but I assume you are if you're asking about what to take. In the email Suva sent me after my 2NL the instructions say "Your original academic certificates and transcripts, plus one photocopy of each;", so I'll be taking my original degree since that's what they are asking for. If you want to be on the safe side I'd recommend just following their instructions lol (although its annoying, mines framed so I'm going to have to get it out, not the end of the world)
