The Immigration Service used to have a dropbox and branch in Wellington, and applications could be dropped off there. This has closed recently, and now I have to send my residence application myself to the Auckland branch.
What's the absolutely safest way of doing this? I don't mind paying for a premier service. The application includes the original full copy of my birth certificate, and this is an essentially irreplaceable document in my home country - so my application basically just can't go missing!
Maybe I'm being paranoid - I've just been reading a lot of the threads about the misadventures of couriers on the NZ Reddit board and they scare me! What have other people done?
