Processing up to 12.4 million litres of milk per day, around 40% of the Co-operatives South Island milk, Clandeboye is one of Fonterra’s largest manufacturing sites.

The site has been in operation since 1904 and has grown steadily along with milk supply in the region to now produce more  than 400,000 metric tonnes of milk powder, cream, cheese and protein products every year.


Processing such large volumes of milk and with a catchment area that spans a 250 km radius around the factory Clandeboye’s manufacturing teams and transport fleets are among the largest in New Zealand.


More than 10,000 containers are filled each year ready to be shipped domestically, as well as internationally to more than 50 countries, including the United States, China, Algeria, Bahrain, Russia, Africa, the Middle East, Indonesia and Australia.



  • Milk processing capacity (peak) of 12.4 million litres per day
  • Annual production – 400,000 metric tonnes
  • 865 staff
  • Nine plants, including three milk powder, two cream, two cheese and two protein plants
  • The largest dryer, D3, can produce 25 metric tonnes of milk powder per hour
  • The distribution centre packs more than 70 containers per day
  • 216 tanker drivers, 76 tankers, each with a capacity for carting 25,500 litres of milk



Mozzarella Plant


The mozzarella plant is the first of its kind in the world. The patented technology means that frozen natural shredded mozzarella can be made straight from milk in one day, rather than two months taken by conventional mozzarella processes.


Milk Powders


Clandeboye’s three powder plants produce about 250,000 metric tonnes of milk powder per year, for export to Asia, South America, Africa and the Middle East.


The range includes whole milk powder (WMP), skim milk powder (SMP), buttermilk powder, milk protein concentrate and instant WMP.


The milk dryers have a combined peak processing capacity of 1,250 metric tonnes per day.


Clandeboye’s biggest dryer is one of the largest in the world, and is capable of producing 25 metric tonnes of WMP per hour.


Cheese Products


Clandeboye’s two cheese plants can produce 61,000 metric tonnes of dry salt and mozzarella cheese per year for food service companies in Europe, the Middle East, North Asia, Australia and the domestic market.


The Dry Salt Cheese Plant is the larger of the two and can process up to 1.8 million litres of milk per day, producing the equivalent of 216,000 one kilogram blocks of cheddar cheese.

Protein Products


The two protein plants produce 21,500 metric tonnes per year of whey protein concentrate and lactose ingredients, which is enough to fill more than eight Olympic sized swimming pools every year.


The protein ingredients are manufactured for use in various cheeses, functional, nutritional and pharmaceutical applications, and are exported to international markets such as North America, Europe, Australia and North Asia.


Environment & Sustainability


The site has an environmental management system which is certified to internationally recognised standards. The key purpose of the system is to ensure compliance and continuous improvement.


Wastewater from each part of the site is tested daily and treated wastewater is used to irrigate to maximise efficiency.


Clandeboye is very active in its community through the Grass Roots sponsorship programme, as well as directly with local community groups.
