New Zealand 1 RNAV

Queenstown has some great approaches.
You have the chart for RNAV Z rwy23
The TBM has it in the system so it can be flown by the AP - with the current limitations that it won’t follow altitude. Oddly the approach is not exactly the same, with slightly different waypoints.
But it is not available to add to a flight plan within Navigraph ie when you click on the approach button it is not there.
