Agriculture Minister Damien O'Connor said the Government is still in the dark over Fonterra's investment in troubled infant formula producer and distributor, China's Beingmate Baby and Child.
Late last month Beingmate issued a forecast earnings downgrade for its financial year ended December 31, revising the previously announced forecast loss of RMB350 million-RMB 500m to a forecast loss of RMB800m-RMB1 billion ($171-$214m).
"We, like a number of concerned farmers, we have not been able to get access to all the information that might be useful," O'Connor said after the official opening of French food giant Danone's upgraded formula blending and processing plant at Mangere.
"Ultimately the farmers, as shareholders of the company, have to work through that process," he said.
Beingmate has struggled to perform since Fonterra spent $755m on acquiring its stake in 2015, and analysts have long questioned whether the 18.8 per cent holding was big enough for Fonterra to influence the company's direction.
