The dairy factory in the heart of Mycoplasma bovis territory could avoid major effects from the outbreak this season.
Oceania Dairy is located near Glenavy, just north of the Waitaki River, and within cooee of the farms where the bacterial cattle disease was first confirmed in New Zealand a year ago.
The factory is owned by Inner Mongolia Yili Industrial Group, China's biggest dairy company and the world's 10th-largest. Oceania Dairy was its first investment outside China.
Since it began operating in August 2014, the Glenavy plant has produced a range of milk powder for export to China, where it is used as an ingredient in finished goods such as infant formula, consumer milk powders, ice cream, yoghurt and liquid milk products.
Oceania Dairy general manager Roger Usmer told Central Rural Life last week it was ''tracking pretty well'' for the new season.
