"They did all they could; they stopped other properties from burning down and no lives were lost. What more could we want?"
Whataroa chief fire officer Ian Philps said the house had just erupted in flames when they arrived on the scene.
"Locals were using garden hoses to contain it, which we believe started as a chimney fire and then got out of control.
"We were first on the scene, and the Franz brigade arrived just before we ran out of water and they took over," Mr Philps said.
Mr McLennan said it was a typical "Kiwi bach" and was formerly part of the original Green family home at Franz Josef, later moved to Okarito.
Parts of the bach were about 100-years-old, and it was "beyond repair".
Another Okarito resident, Debbie James, said a young couple had been living in the bach for a couple of years.
"The man was away at West Coast rugby training at the time of the fire. His partner, who has a business locally, and their dog, got out safely."
Mrs James was also impressed how the community united to help the couple with their loss.
"There's been great support for the couple, and the fire brigades did well."
