The most likely cause of the fire that severely damaged Whangārei's Old Town Hall is an electrical fault in a light fitting, according to experts sifting through the charred remains.
A blaze broke out in the 107-year-old building last Thursday about 12.45pm, forcing the evacuation of community groups that use the property on Bank St in Central Whangārei.
Firefighters were quick on the scene and able to isolate the blaze to one corner of the building. However, the landmark clock tower was severely damaged and had to be removed and taken into storage late on Friday.
Specialist fire investigator Craig Bain was able to get into the building on Friday morning and identified the seat of the fire as starting in the false ceiling cavity in a top-floor room used by Literacy New Zealand.
The instability of the clock tower meant further investigations were halted until it was removed.
