More than $5000 was also donated to the couple through a bank account and donations made tonight, he said.
"That was extremely overwhelming for them."
He said the generosity of people had touched the Thoms, whose house wasn't insured at the time the earthquake hit.
"Compared to what they've lost it's not a lot."
The house included appliances such as a dishwasher and wall oven, and the buyer has until August 11 to salvage what they can before the site is cleared.
The Thoms' goal was to raise enough money through the auction to get to the United Kingdom to visit family.
To help them on their way real estate firm Harcourts Grenadier waived all fees and commissions, and guaranteed the couple their trip to the UK out of their own pocket, regardless of the sale.
