.. Apparently they are no longer there. I've searched but cannot find the AI package any where else. Would anyone else be able to supply it? Thank you.
The Wanaka package was done some time ago, and sadly the referenced AI I used at the time, are indeed gone.
But Nigel is on the right track: the ACG Duxford package at flightsim.com

has suitable aircraft which can be subbed into the Wanaka aircraft.txt file (in bold red below):

This leaves the Convair 580 which exists on the internet (search Greg Pepper), and the Pionair Dakota which I think is a flyable repaint. Perhaps one of the ACG Daks would do...
I don't know if any of this has been any help at all - I always intend to repackage this with planes included.
Takes a bit of permissioning and so on, I'm lazy about it is all.
Oh, and the supplied AFCAD is for the RealNZ scenery, now freeware, by Robin Corn.
