Runway works at AKL will not cause the HNL stop for inbound services, just outbound. Inbound to AKL, the 743 will be a min fuel weight anyway.
Trans-Pacific head winds are strong at this time of year, so if they need to carry the extra load (lots of pax plus freight) then its going to need a planned stop, and HNL seems to be QF's preferred location for a tech stop. At least they have ground handling agreements in place for the passengers.
If the flight is scheduled as LAX-HNL-AKL, then passengers departing LAX will not be permitted to purchase duty-free at LAX. They will have to do that at HNL as US laws only permit duty-free goods to be delivered to the aircraft door at the point of final departure from the USA.
All the more reason to be informed regarding airline schedules and plan accordingly. Of course last minite changes can always kill a good plan
