The owner, who did not wish to be named, rented the property to Bunim-Murray Productions, a United States production company, which used the property to film the show, Duel II.
The programme, now screening in New Zealand on MTV, was filmed last summer in the secluded property, which looks towards Coronet Peak.
Twenty-six contestants lived in the house for the show - a cross between Big Brother and Survivor - while the owner and his partner were on holiday in Borneo.
But reality TV turned into something of a horror story when the owner returned home and discovered the mess.
He said while he "expected to see some damage", he had not been counting on having to call in lawyers to settle a dispute over the costs.
"It was pretty bad . . . My house now has been completely repainted [and] all the floors have been done."
It is believed a makeshift waterslide had been erected inside the house by the contestants.
Red wine stains were left on the marble floors, all of which had to be resealed and polished.
The owner said his biggest concern was the production company's failure to accept responsibility for the damage.
He said while they did "partially" repair the damage, as a former building contractor, he found the repairs were not up to standard.
"It wasn't major like everybody makes out - you can fix anything, it just depends on how much money you want to spend.
"They organised to get it all fixed and all the damage has [now] been repaired."
Despite the problems, which led to a delay in putting the house on the market, the man had not ruled out renting his house again to production companies.
"I would consider it but . . . I was a bit naive [about] the bond they put up."
In a statement to The New Zealand Herald, Bunim-Murray Productions said it had a "wonderful experience" filming in New Zealand.
"As always, if a property is damaged during production, it is repaired and returned to the owner as it was originally found."
