As an aside, QF does the opposite at LAX.
What charges are you referring to?
I seriously find this possible and have looked at the two airports sites to see if they have information regarding parking charges.
SYD $38.50 (GST inc) per 15 minutes
sydneyairport.com.au Table of Charges
MEL Free if you have an Air Services Agreement with the Airport or less than 48 hours for those without one, but can be up to $50 (GST inc.) per 15 minutes

EK fly to NZ as it is part of its global strategy, nothing more or less.
