Hi sarfoo4u,
I can't probably help you too much as I'm in similar situation as you still looking for an opportunity in NZ (as a web applications developer).
I also created profile on seek and regarding linkedin I started adding to my connections people from NZ with similar job profile and agents. Up to now it didn't help yet but it can make it easier for NZ employer to find you if your profile matches the requirements.
Anyway, please let me know how was your trip to NZ, did you have any interviews there, and what was the result?
Hope to hear from you!
cheers
