What a load of BS. Qantas pioneered the Queenstown RNP approaches years ago, and still fly them today.
QF and NZ both pioneered the Queenstown RNP AR operation at about the same time. QF was the first to fly the ZQN approaches due to operating the NG which has a far better RNP capability and they we also the first to be approved to operate below RNP 0.3, while NZ had to upgrade the CL aircraft first and was about 6 months behind in the starting of gathering the required number of approaches.
Both QF and NZ are behind Alaskan and Westjet who were the first to use the full aircraft capability in the North America
Since then QF has really accelerated the RNP program and are way ahead of NZ with the Boeing B738 and the number of RNP operations, while NZ concentrated on the A320 approvals and getting Airbus into the program.
