I also interviewed in Auckland last week (I assume thats when you interviewed). They said they'd get back to me 2 weeks from my interview date, which was Sept14.
As for people getting to stage 2 with an average stage 1 interview, I cant really help you out there. All I know is that I interviewed last year and totally bombed, needless to say I didn't get to stage 2. I feel this time went much better though.
Good luck to ya!
