No
self regulate
just a kind of kite school certificate and insurance before buying a kite, based on self regulations by the schools, shops and 2nd hand kite sellers.
just be happy there are "crowded" spots, that means kiters are not on the other good spots.
usually the crowded spots are not the best, but the closest to city. its better to have 2 spot with 30 kiters and 4 spots with 5 kiters, than 6 spots with 13kiters (about same number total of kiters).
there are no crowded beach in australia
look what that means a crowded beach in winter in france (12degrees air and water).
and most of them are not locals, and drove 2h to get there. there is twice as many kiters and poleys in spring, never less than 100 kiters on windy week ends above 15°.
it still works without any regulations, not much accidents happen there, but they are fighting to keep this spot open, cause its near a nature reserve, and the local council want to close it to "save" bird species
