All Airline's are strick about height , And if you are a female Crew Member you wear Cabin shoe's which will not be of any help if you are short and the overhead locker's are very high (747) and most important the galley stowages are high too (747) . And I know I should be a gentlemen, But Being a Male crew Member . You get tired of being asked by your fellow crew member please can you reach for that stowage and it's usually where the water bottle's are and which are very heavy . I hope you do get an Answer from NZ .
Good Luck
