Thanks JandM for your detailed explanation.
So it seems that the outcome for my application depends much on the interview now. I just wonder if INZ takes much into consideration the effort one makes to find a job in NZ while he/she is still in his/her home country? (Something like though you might not get a job yet, they do count when you send your CV/contact recruitment agency there).
I'm a bit worried now because I told my CO that I haven't contacted or applied for any job there, but wait until I go there so that I'm available for the interview. Also, for my profession which requires communication skills, recruiters usually want face-to-face meeting so they can assess the potential candidate. Besides, I told my CO that even so, I follow up with those job ads on recruitment websites and also contact my friends in NZ (who work in the same field) for a recommendation when I get there. Do you think this is convincing enough?
I'm just afraid they think I didn't do enough work to find a job there and then give me a JSV, which I'm not really looking for that

Please provide your personal view on this.
Thanks
