Here is the real deal-breaker for elites and Koru Club members. The lounge will be three times the size of the current Air NZ lounge - but will have to cater to eight airlines rather than the current three.
I can't see it being worse than the present situation. With the current lounge, it's not so much the number of airlines and flights that's an issue - but the fact that most of the flights go out in a cluster in the evenings: 2xVS flights and 2xNZ flights all within about 3 hours of each other!
It seems like there's typically a high proportion of pax on those VS flights who have lounge access too
