It looks like part of the confusion with Kumali/Malumba relates to a mistake in IMDB, where Gordon Petrie is listed as Big Mulumba, in the weekly New Zealand wrestling show, "On the Mat".
I think IMDB can be edited by any registered user (like Wikipedia), so maybe someone saw the wrong information on a wrestling site, such as I posted above, and then edited IMDB?
Either way, as can be seen at the 3 minute mark of "On the Mat" from March 17th, 1981, this is not Gordon Petrie.
