The receivers of Crafar Farms say they are not aware of any interested buyers and it's too early to know if the company will be broken up or sold as one unit.
KordaMentha was appointed receiver of Crafar Farms on Monday at the request of its banks, Westpac, Rabobank and PGG Wrightson Finance.
The company has debts thought to be worth around $200 million.
All 22 Crafar farms in the central North Island have been on the market after a series of run-ins with authorities.
In August, Allan and Frank Crafar and Allan's wife Elizabeth were fined a record total of $90,000 for illegal discharges of effluent.
Checks are also being made by the Ministry of Agriculture after more than 100 starving calves had to be shot on a farm in Waikato.
Receiver Michael Stiassny says the first priority has been to ensure the welfare of the livestock, after which they will focus on addressing the company's financial problems and how to repay creditors.
