NZCH What GHA are there
 

Does anyone know what GHA's are based down there? Swissport, Menzies or the other one?

GHA? Like FBOs or the ones the airlines use?

if you’re running a bizjet charter through there I think
GHC runs a big (expensive) facility there

GHA - Ground Handling Agent:

Menzies, Swissport etc. Wonder who services QF/EK/CX/SQ etc

Skystar (Perth Based) used to have operations throughout WA, in Queensland (Hamilton Island) and Christchurch. They sold out to Menzies (Skystar Airport Services was owned originally by Mondelphus Group Limited, a Mining Company). I know they did JQ in CHC (the reason for setting up there) so when Qantas and Air NZ parted ways for GHA, I suspect QF would have gone to Menzies as well.

I also suspect NZ might still have Ground Operations there too. They certainly do in AKL.
