Police and firefighters were called to the scene on Sunday night at a property on Kimwana R in Wairoh.
An on-the-spot investigation will begin into the property, which is considered a gang pad, in Verua after it was destroyed by fire Sunday night.
This property is believed to belong to “The Trident” on Kamwana RD, Mangal Mob.
Emergency services were notified of the blaze just after 6 p.m., with two firefighters involved. The fire was brought under control after 8.30 pm.
Detective Sergeant Sam Park said one man was asleep in the building at the time, but he escaped injury.
A security guard was posted on the property overnight.
Police and fire and emergency New Zealand investigators will work together to determine the cause, but initial indications are that it is not suspicious.
