A five-bedroom house in Greville Harbour, D'Urville Island, owned the the Conservation Department has been destroyed by fire.
DOC sounds area visitor assets manager Mark Nelson said the house burnt to the ground on June 20.
Two workers who were staying in the house were out fencing on the island when the house caught fire. They returned to find the home burnt to the ground.
A fire investigator and DOC fire investigator have been to the island to find out the cause of the blaze, which was not considered suspicious.
Mr Nelson said on the day of the fire the workers had woken up to find some smoke in the lounge.
They had done everything right and cleared the fire out.
DOC took possession of the house after the Nature Heritage Fund bought the land and gave it to DOC to look after.
The family that had stayed in the house had finished their two-year stint on the island two weeks before the fire.
Mr Nelson said DOC was still working out what to do and it was possible that a campsite in Greville Harbour would be moved from the Dune area to the house site as it was more sheltered.
He said the fire was a huge loss and staff who had stayed in the area were upset.
Mr Nelson said access to the island was difficult but it was hoped that a barge service between French Pass and Kapowai would encourage more people to stay in Greville Harbour.
People would still be able to visit but they would have to camp.
The area was stunning and had recreational opportunities, including mountainbiking.
"It's a spectacular spot, great walking, some mountainbiking ... the wilderness is amazing. It's one of those places that will take your breath away. Every New Zealander should go there at least once in their life."
He said the house had asbestos and the site was currently hazardous.
DOC was trying to get it professionally cleaned and at the moment it was not a place for sightseers.
People who did visit before it was cleaned up should not be tempted to rummage in the house's debris.
