Congrats on getting your registration! I'm very jealous you're at the end of the whole process!
I'm currently in the middle of doing it all. I'm planning on working in Australia, but am going to register through New Zealand first as it seems to be the easier and cheaper option.
Can I ask you how long it took to actaully gain your registration once you sent off your application pack? Did they come back to you with any corrections?

Thanks
