Maybe no need for first class but it would be nice to have a differentiated lounge for Elites, especially with the crazy crowds at AKL in the evenings.
I'm often a little jealous when I walk past the Qantas first lounge in LAX on my way to the Star Alliance lounge where NZ won't let us in the First Class section (even VA used to do it for their Platinum members before they switched lounges)
