Skytops - Id say the chances are like trying to get C-Cat work out of most other organisations you didnt train at yourself: Slim - especially if your still under supervision. Having said that though I think it was Scott air that where 'welcoming applications' from C-Cat instructors a couple of months ago but once again were looking for persons out of supervision.
Ive also read on here that Massey's Palmy op. is closing down so I would imagine you would be competing with the instructors from down there for somewhere to go.
If youve almost got the mins for a B Cat hang in there - Mainland Air, Manawatu aeroclub, and the guys in Rotorua are all looking for B Cats with various min experience. Also i believe a few Massey B-Cats are jumping ship to Flight2000.
All the best anyway!
