ABOUT us

Here For You

Mainfert prides itself on focusing on the client, the farming system, the soil and the long term. We like to think of ourselves as providing solutions to a whole range of challenges facing today’s primary producers.

There is no “silver bullet” product out there – just good innovative advice based on research and experience. Whether your farming system is more traditional, or you are moving to a more regenerative and biological system, we will meet your soil, pasture and animal need.

Many will know us as Mainland Minerals and with over 30 years supplying nutrient solutions to South Island farmers we rebranded to Mainfert mid 2020 to better reflect what we do and who we are.

We want to help farmers to achieve their financial and environmental goals through their biggest asset, their soil. We have a unique range of fertilisers and Mainfert prides itself on focusing on the client, the farming system, the soil and the long term.
