We were first to check in for AKL-HKG on the 4th April (the flight that was eventually delayed for 5 hours) and were approached by a chap in uniform and offered $NZ 2000 for J-PEY or $NZ 4000 for J-Y each. We needed a good sleep that night so declined but would have been open to being put on the next days NZ flight if they could have coveredall the changes to the onward flights/hotels too.
