The Government has included a clause in its $10 million loan contract to Westland Milk which allows it to exit the deal in the event of a major change in ownership.
This comes as the dairy co-operative's Chairman Peter Morrison confirmed Westland had "entered into a strictly confidential discussion with a select number of interested parties."
Although Morrison won't confirm who the interested parties were, the Australian has reported Canadian dairy giant Saputo was eyeing up the co-op.
This may prove to be problematic for Westland, given its $9.9 million loan from the Government's Provincial Growth Fund (PGF) late last year.
In a statement, Regional Economic Development Minister Shane Jones said although the contract between the Crown and Westland was still being finalised, the PGF reserves the right to revisit any funding decision prior to a contract being entered into.
