I will have a flight from Seoul, Incheon -> Tokyo, Narita -> Auckland, NZ -> Sydney, Australia, all in one booking.
As it is in one booking, in most cases you should be able to check-in once and you will have all of your boarding passes available at the same time.
My question is if I can get all 3 flight boarding passes when checking in at Incheon airport with Asiana?
You might have to check with the airline. You can check online right now by viewing your booking and seeing if it displays all 3 flights or are they separate. It is better to arrive to the airport with time to spare just in case.
I notice that Seoul-Tokyo is a codeshare flight between Asiana & ANZ, but onward flights from Tokyo-Auckland-Sydney are solely operated by ANZ.
It may well be that you have to get boarding passes for the first 2 flights and separately for the 3rd flight, this has to be checked in your booking/with the airline.
