A family house in Avatiu Valley was razed to the ground on Tuesday night and a workshop in the Arorangi-Blackrock area was also destroyed, after midnight yesterday.
Rescue Fire Service chief fire officer Willy Hagai said the service was told of the Avatiu fire at 7.30pm.
He said by the time they reached the scene, the fire had engulfed the whole house.
“We were unable to make out how many bedrooms it had, but from what we saw, we believe it was a two-bedroom house,” Hagai said.
“It was occupied by two people. They said that they smelled plastic burning and got themselves out of the house.
“They only managed to save a car and a bike and were unable to salvage the rest of the items in the house.”
Hagai said they received the report of the Arorangi fire at 1.30am yesterday and by the time they reached the scene, it was too late to save the workshop.
No-one had been injured in either fire, he said.
On Friday last week, one of the Bluesky Cook Islands’ core sites in Aroa, Arorangi, was completely destroyed by fire, disrupting mobile network services to Rarotonga and Aitutaki.
Early on Saturday morning, the Rescue Fire Service team managed to contain a fire at the First Windows and Doors office in Nikao.
The Rescue Fire Service and the police are investigating the incidents.
Hagai said they were concerned that four fires had occurred in five days and were asking the public to be vigilant at all times.
“It’s quite a noticeable amount of fire cases for a population like ours. We are not aware of the causes yet as investigations into these fires continue,” he said.
“I think people need to look out for their properties and make sure they are safe from fire. If (you have) buildings with old wiring, get a qualified electrician to check them.”
