Representatives from Infinity Investment Holdings Group Ltd and Bayleys Wanaka have repeatedly refused to disclose details about the sale.
It was reported on RadioSport's Monday lunchtime programme The Farming Show, that TradeMe founder Sam Morgan was the buyer.
Mr Morgan has not returned phone calls and email messages sent to him by the Otago Daily Times.
Infinity managing director Bob Robertson said the company was aware of speculation in Wanaka that Mr Morgan was the purchaser, but preferred to get settlement "out of the way before we make any comment".
"Our contract has a clause of confidentiality. It [the buyer's identity] is not something we can disclose."
Mr Robertson said he would have "personally" preferred that details for the successful tender of Hillend were public, because of the propensity for mistaken media reports.
"From my point of view, I'd like the price it has been bought for to be out in the open . . . it doesn't bother me. It's easier if things aren't confidential," he said.
Bayleys Wanaka agent Trevor Mackay asked for the privacy of the buyer to be honoured.
He declined to discuss whether Mr Morgan had purchased Hillend.
A media statement from Infinity and Bayleys is expected this week.
