The Financial Markets Authority says it ruled the late Jock Hobbs out of its investigation into Strategic Finance in June last year because of medical evidence.
Hobbs, a former All Black, passed away last week after a six-year battle with leukaemia.
He was a founder and one of six directors of Strategic.
The property financier struck trouble in 2008 and was placed into a moratorium owing more than $400 million to 13,000 investors, many of whom were elderly.
It has since gone into receivership.
