Westland Milk Products says its move into higher value nutritional products is paying off with increased orders.
The company makes a range of protein products, buttermilk powder and anhydrous milk fat (AMF).
The dairy co-operative commissioned a new infant formula plant at its Hokitika base last year which will continue processing through June and July to meet the orders it is getting.
The company is also encouraging some of its farmers to milk all year round to make better use of its processing facilities.
Chief executive Rod Quin says it's had enough interest so far from West Coast and Canterbury farmers to supply 40,000 - 60,000 litres of milk a day during the traditional off-season.
Mr Quin says the plants are able to run all year round and can run using smaller volumes so it's still profitable to make products at that time of the year.
He says it allows Westland to make money off low volumes of milk supply, which wasn't previously possible.
