I'm flying Air New Zealand to South Africa via Perth tomorrow. I've just discovered that there's no Koru lounge at Perth airport which means that my silver Airpoints lounge passes won't work.

I looked into joining the Koru club, but because the second flight from Perth to Joburg is an SAA codeshare with AirNZ, that won't work either.

I'm flying there and back in a single week and will have to do the 7 hour stop-over twice, which I am really dreading. Does anyone know of any way that I can buy a pass for any of the lounges at Perth airport? I can't find any info anywhere. The lounges are Qantas, Emirates, Malaysia and Singapore.

Any advice really appreciated!
