AEA ran an ad in the NZ Herald earlier this year for crew. F/O requirements were 2000TT and 500 multi crew. 727 rating preferred.
Although this was the published min I dont know what you really need to get in.
Lots of the postions used to be filled by ex RNZAF 727 boys. I would suspect these day it would be boys looking for something fairly part-timish after a career on jets.
