"My original routing was HKG-SYD but it looks as though I will have to change that to HKG-BNE and connect on to QF25. There seems to be "L" availability AKL-CHC so that will get me to the first test!"

Im confused. Why would you want L availability if you are using a DONE4. Surely you want D availabiliy. Also, if you would rather go SYD-AKL rather than BNE-AKL, the QF321 flight is valid to use since the operating carrier is also OW.
