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.
