Wow pretty scary, same technique as money scams but much more dangerous... Good on you to share you're experience.
You're on WHV in NZ? I was there last year, I can only recommend you to read some posts of my dear friends @bluudz (life is out there) and @gomart
They are both still in NZ travelling, so you can contact them if you need anything. Same thing if you need a place to stay in Auckland I can give you a good adress where you'll be very welcome.
Good luck, enjoy NZ
And cheeers mate!
