Are the rest of the NZ gliding clubs looking at the same fate?

No, or should I say, probably not.

Glide Omarama was the only overtly-commercial gliding operation in NZ. They paid their instructors - not a lot, but they paid them. To CAA, this put them well into the "Part 115" category. The two parties have been in discussions for several years but the recent culture shift at CAA has caused them (CAA) to read the law rigidly, rather than adopting a more relaxed interpretation for the greater good etc..

Many other gliding clubs in NZ have "summer crew" of visitng instructors who aren't paid a salary but get free accommodation (usually in some decaying club caravan) and the other club members provide food. A CAA lawyer with a grudge could interpret this as 'financial reward' but this would be viewed by GNZ (and probably the broader aviation community) as the most miserly, draconian and archaic interpretation of the law.
