"What's really promising are the trends we're seeing in cheese, butter and UHT over the years - not just in the sale of dairy products, but how they are being consumed," he said in a statement.
"Particularly as the major urban centres in China shift away from oils, people are actively seeking more dairy in their diet whether in their cooking, as a table spread or in a glass," Watson said.
Dairy beverages such as tea macchiato - which mixes tea with cream and cream cheese - showed consumers were willing to be bolder with dairy applications, he said.
Fonterra's chief operating officer of global operations, Robert Spurway, said the new facilities would help Fonterra keep pace with changing customer preferences.
"The new technology we're introducing at Darfield will give us the flexibility to quickly change our products to suit that need - a real game changer," he said.
Once the project is complete, Fonterra Darfield will become one of the largest producers of cream cheese in New Zealand, alongside the co-operative's Te Rapa site.
Globally, the foodservice industry is growing around 6 per cent every year. Expansions such as these, which are backed by customer demand, have helped Fonterra's foodservice business triple that figure over recent years.
Fonterra's out-of-home foodservice, supplies the trade with culinary creams, bakery butters, and a variety of cheeses including slice-on-slice, shredded and extra-stretch mozzarella.
