Been lurking for a while, decided to finally introduce myself. I'm Anna, originally from the UK, now living in Wellington, NZ (currently on a student visa), planning to apply for residency on grounds of my relationship with my g/f. I've got it easier than a lot of people as the NZ government recognises same sex relationships on an equal basis and doesn't require a civil union, but still immensely stressful. When I recieved exam results in the mail my first thought was "yay, proof of address for the immigration dept".
I pretty much know the rules inside out (and I haven't even submitted my application yet) so if you have any questions about immigrating to NZ I may be able to help you out.
