Well I work for AirNZ as a Customer Service Agent, And have been there for coming up 2 years. They have no problems hiring Uni students if they know that they will still be at uni for a while, last thing they want to do is to train them, then 6 months down the track they leave after they are done with uni.
I dont quite understand the not telling them your a pilot thing, I did that for my interview, hell it was the only qualification I had after leaving school, and it went down a treat. It showed that I had a good understanding of the industry and everything that was involved. Rather than being some brainless bimbo off the streets that thinks that a cockpit is something in a guys pants.
But then again this is AirNZ... Not Aerocare.
