Chris Dugdale, of Dugdale Charitable Trust, said the afternoon went "really well".
"We are delighted with the outcome," she said.
"I think it was a fair price."
She said there was some strong bidding and it was a really exciting auction.
They were also running a competition for people to guess how much the house would sell for and the purchasers won; "that's the price they paid for it".
The UCOL charity home would remain on the market until a suitable offer was made.
"I feel if we just wait a little, somebody will come along who says 'this is the house for me," said Mrs Dugdale.
Other items up for auction, including a brand new Hyundai car from Eastwood Motor Group and a Harvey World Travel voucher, were also sold.
Proceeds from the UCOL home will go to Asthma Foundation New Zealand and Lifeflight Trust.
