What if NZ {or elsewhere} made a rule that you can seek, approach and kill the critter any way you like {so all those techie advances can be ignored}, but once the game is down, no motor vehicles may be used while you possess fresh game parts {hides, head, meat, etc} until you reach a state or national highway where you may use a car/pickup or whatever to get back to civilization.
So, you must WALK out from wherever, using no motorized vehicle to assist you in retrieving game, trophies or gear and at least for most animals here in the states, game wastage laws would require the entire meat quantity to be packed out.
Just as hard to enforce no doubt, but it would be fun to see in action...
Sorry for the off topic, but I like brain teasers...
