He was 67-year-old Robert Earle Corson.
A police spokesperson said initial findings indicated the fire was not suspicious.
"Enquiries are still ongoing in relation to the matter, including enquiries on behalf of the coroner," the statement said.
It is the second Aotearoa Natives "clubhouse" to burn down in Greymouth.
On December 15, 2020, fire destroyed a Thompson Street address where the gang had set up.
That fire was treated as suspicious and gang members subsequently moved to Cobden.
