The RNZAF, as might be expected, did many things, and still does probably, which were identical to those in the RAF, and one was that personal letter from CAS when you left...except in my case they had the name and rank wrong!

The CAS at the time was new, so I wrote back enclosing said document and I might have included some comments on Chief Executives only being as good as their underlings allowed them to be and that such errors as appeared in my letter were really quite unacceptable...
To his credit I got a very personal response, correctly addressed
