Thanks for the responses. I am currently on a DONE4 out of JNB, have only the SYD-JNB leg left, and was thinking of changing to SYD-AKL-SYD(less than 24hrs)-ZQN-SYD-JNB. I was expecting to pay 2 extra PMCs (on top of the original one), but this should mean that I don't pay any additional PMCs, which would be nearly $100 now. Great news. Thanks.
