Delta's Luggate Park joint venture with property developer Jim Boult is on the market as a deadline private treaty sale closing at 4pm on November 14.
Included in the sale notice are seven residential lots and two "future development sites" amounting to 51ha consented for 160 residential lots.
Delta has already written down its Luggate Park investment by $5 million.
Its annual report values its total current assets in the joint venture at $493,000 and lists as a current liability a Westpac loan of $868,000.
In the year to June 30, 2012, Delta earned $2000 from its Luggate Park development and spent $79,000.
Colliers agent Rory O'Donnell said he had had "some interest" in the development but it was hard to know where buyers would price it.
Mr O'Donnell said development land was "harder to sell" at present because less bank funding was available to potential buyers.
"[The banks] are a wee bit reluctant to lend on development land."
However, people were "creeping back into the market" looking for development opportunities, Mr O'Donnell said.
Delta also owns 100 sections at Jacks Point, near Queenstown.
In September, chief executive Grady Cameron told the Otago Daily Times the company would develop the sections' infrastructure before selling them.
The company's annual report says a decision to exit its development property ownership would mean booking a $7.5 million pre-tax write-down.
