Nutritech has stood the test of time from the humble beginnings of a single Danish chemist in 1915, to become known as the Danish Mineral Research Company. The name was later changed to Nutritech International Limited in 1985. Nutritech was the first company in New Zealand to make and sell mineral mixes to New Zealand farmers. The company soon became known for innovation and quality products that improved animal health, prevented deficiencies and improved productivity.


Today we are committed to continuous improvement. We have recently relocated and upgraded our factories in Rolleston and Auckland and a technically superior sales team covering the entire country. Nutritech has come a long way but our vision has remained the same: To be the first point of on farm nutrition advice to New Zealand Farmers to optimise production and animal welfare.

Our products are based on sound, modern nutrition and science, with 100 years of experience in the New Zealand market. We have taken into account the diverse range of conditions, systems, performance and pastures across NZ – and have tailored products to specific areas of the country. They are targeted toward removing nutritional limitations and bottlenecks. They deliver the required, balanced doses to animals at the critical times in the annual production cycle to optimise performance. Our products are high specification, delivering real value for money, when it comes to cost per dose.

We’re training the future…

Our vision at Nutritech is to be the first point of contact for
on-farm nutrition advice for New Zealand farmers

Achieving this vision takes many aspects, but a key pillar in our strategy is to be technically strong. Our customers’ needs are often complex, so technical competency is critical to enable us to offer nutrition and forage advice that adds value.

We aim to offer market-leading breadth of knowledge and experience with four full-time nutritionists and two consulting nutritionists.

Recently Nadine Olsen and Louise Salter completed their Australian Association of Ruminant Nutritionists membership by examination qualification (AARNe). National Technical Manager Alun Faulkner says, “They both put a lot of hard work into passing the AARN examination late last year.” The AARNe (membership by examination) is a professional qualification that indicates they are advanced advisors with competency and expertise in the field of ruminant nutrition”.

He goes on to say, “Having qualified ruminant nutritionists who understand the complexities of both pasture and high input systems gives our team confidence when offering technical solutions to our customers.”

The technical team supports our regionally based twelve Area Managers, many of whom hold a tertiary qualification. We extensively train our team on the value of our products, animal nutrient requirements and forage best practices. This additional support from our technical team ensures we are the leaders in the animal nutrition and forage industry, allowing Nutritech to add value and support our customers and their businesses.
