The chairman of Fonterra, John Wilson, has confirmed the co-operative is in talks with Argentina's main dairy company, SanCor, over a possible tie up but said discussions were "at a very early stage".
Argentina's two biggest newspapers, La Nacion and Clarín, have been carrying reports that said Fonterra had been in talks with the indebted SanCor, which is also a co-operative.
"SanCor and Fonterra are certainly talking at the moment, but that is all that is occurring," Wilson told the Herald.
"Our management team is talking with different entities globally on a continuing basis - that is the nature of our business," he said.
"Clearly SanCor has had a challenging period and they are having a chat with us at the moment, but it is very early days and nothing is really occurring at all," Wilson said.
