I understand that there is a subtle but serious distinction between the Oz 1:36 ratio and the NZ 1:50 ratio. The Oz ratio is 1 F/A for every 36 seats fitted to the aircraft whereas the NZ ratio is 1 F/A for every 50 pax which means that with a less than full load the airline can further reduce the numbers of flight attendants. This could leave emergency exits exposed for pax to open without checking for fire etc. This is potentially a very backward step being driven by accountants who run airlines.
