The fire was "fully involved" when the brigade arrived.
A fire at the Tribesmen gang pad in Murupura in the early hours of Monday morning has been deemed "not suspicious" by police.
Rotorua police area commander Inspector Phil Taikato said the fire, which took place about 2.50am, was not arson and the circumstances were "not suspicious".
"All concerned are
satisfied with this," he said.
A Fire and Emergency spokesperson said the structure was "completely burnt out" which made it "impossible to determine the cause".
Earlier, a spokesperson said firefighters received a report of a building fire in Murupara about 2.50am on June 6.
