There were quite a few NZ cottage industry businesses making wheels during the late 1960s and early '70s. They were usually a cheaper and more accessible alternative to the expensive products being produced in other countries. Graeme Addis was another one making wheels around that time.
The Span wheels are aluminium, so not that light , I had some 15" x 14" or 15" on a T bucket back in the early 80's and they were magnesium, no name so could have been locally made.
