Investigation reveals devastating Wellington marae fire was accidental

An investigation into the cause of a fire that destroyed a Wellington marae has found there was no foul play, but the building's alarm system failed.

Tapu Te Ranga Marae in Island Bay burnt to the ground on June 9. 

The Fire and Emergency investigation found the likely cause of the fire was stray embers from a brazier which had been extinguished.

"The brazier had been used in an open area at the marae the previous evening, but was extinguished around 8pm because of concerns about ember transfer," Fire and Emergency said in a statement on Friday.

Tapu Te Ranga Marae went up in flames shortly after midnight.

The marae had an unmonitored fire alarm system installed but it had failed to operate the night of the blaze.

This was because there had been a false alarm earlier in the week, and the alarm had not been reset by a technician as it should have been.

"This fire is a real tragedy for the marae and the wider community who use the facility," said Fire and Emergency Wellington area manager Dave Key.

"But it does demonstrate just how dangerous hot embers from fires can be, even when it's damp and cold."

A GiveALittle page made to fund the rebuild of the marae has raised more than $80,000.
