I'm trying to solve this Geocaching puzzle.
NZ NO PE KR AT AT PE AT UK MM SE
Hint: Puzzle includes acting
The answer to the puzzle should give some GPS coordinates, most likely in the following format: N 54° 59.000' W 001° 35.000'
The only thing I can find that looks even somewhat close are the ISO Country Codes, but I'm not sure how that would relate to the hint.
