He opened his window to see the house north of his was on fire. He then opened the curtains and realised two homes, a barn and several outbuildings were also on fire.
"I thought 'it's Armaggedon' . . . it was terrifying."
The resident got dressed and went outside to find one of the neighbours whose home it was running down the street.
"It's not pleasant to sit there and watch someone's house go up in flames and there's nothing they can do about it."
Nobody heard or saw anything before the fires started, she said.
Carterton Mayor Ron Mark had spoken to firefighters at the scene and said, while the cause was still to be confirmed by police and fire investigators, it appeared the fires were started on the outside of buildings, with multiple structures catching fire.
"You know, one after the other indicates highly an arson attack to them."
Mark has told Stuff that one of the buildings was set on fire while firefighters were trying to put out a separate blaze.
Authorities are investigating the circumstances behind the suspicious fire in several homes and buildings on Wards Line.
A neighbour across the street from the blazes said they knew all the people affected and it was "pretty devastating for everyone".
The homes and at least one barn are affected at two locations on the same road.
When fire crews arrived, they realised other homes were on fire on the same street - and raised the situation to a fourth alarm.
Up to eight fire engines and three tankers were at the scene as well as other support vehicles, but the fires have now been put out.
There are no reported injuries at this stage. However, authorities confirmed the fire is being treated as suspicious and up to five specialist investigators are at the scene.
