The head of the country's largest company, Fonterra, says the growing Ebola epidemic could cost the company $150 million.
As African countries locked down their borders in an attempt to control the disease, demand was dropping for Fonterra products, chief executive Theo Spierings told TV3's The Nation today.
"So ... movements in West Africa become more and more difficult, so that limits movement of food as well, movement of people - people going to the market, doing their groceries - so you see demand really dropping pretty fast.
"And Ebola - the question is can it be contained quickly, but it doesn't feel to me like that it is under control at the moment, and I'm saying it mildly."
He was worried the disease would continue its spread across countries.
