Flight attendants will be given the option to wear a green coloured dress if they don't like the pink. In my opinion, the design on the dress (ignoring the colour) does reflect the local culture with the Maori koru design being the main feature. I personally really like it. I don't however like the waistcoat for the men.
The timing of the new uniform is to coincide with the delivery of the new 777-300 aircraft which will have a new interior similar to the uniforms (not in pink)
