"I could just hear that my wife was in the house screaming."
He said it was not until he went to check on his wife that he realised how lucky she had been.
"She said she saw flames shooting out of the telephone as she walked past it. She had actually hung up the phone just before, because she was talking to her daughter, but she said she would hang up the telephone, because you don't use phones in storms.
"Just a few minutes later, this happened, so it was just as well."
The couple were used to electrical storms in the area, but had never experienced a direct hit, because they lived close to a repeater station located on a large hill.
"I didn't think it would miss them and hit us, but it must have been the angle it came from."
Waitaki District emergency services manager Chris Raine said Mrs Sutherland had done the correct thing in hanging up the telephone, because telephone cables could conduct an electric current.
"If you're inside a house, you should shut your computer down and not be near any electrical appliance, and obviously, don't use your phone."
People should also stay away from tall objects and anything made from metal, if they were caught outside during a storm, he said.
"If you're caught in a storm, really, you have to get low, and if you start to smell a strange smell, which is ozone, it indicates that the air is becoming ionised and something is about to go crack."
