Hi Wolfgang. The author is Tim Hanna, but I don't know the name of the book. Ray Battersby had a copy picked up by a motorcycle friend of his who was traveling in New Zealand. As of the past summer the book was not available in the U.S. or Europe. I suspect it is the same for South Africa. The original title was supposed to be Kiwi on the Konig, but that is apparently not the name at publication. Ray sent me a PDF with the cover and some acknowledgements, but I can't find it. I haven't corresponded with Tim in awhile. I will see if I can find out all the info you ask.
