The only traffic file I can recall for Wanaka would be "Traffic_Wanaka_Addon.bgl"
If you have other Wanaka traffic files they may conflict and I can't help you.
Also I remember the readme was wrong about the AFCAD file, cut and paste it to:
"...\Flight Simulator 9\Addon Scenery\scenery" and check that it's the only one. If you already have an AFCAD file for NZWF, you should rename it to something like AF2_NZWF.old before copying over the new one.
Finally, you should download and install the MS FS Traffic Toolbox at
http://www.microsoft.com/games/flightsi ... ds_sdk.aspAI traffic often does not arrive when you think it should (or when you told it to!) This is just how it is. The traffic toolbox will tell you where the AI is and what it's doing.
Hope this helps.
