Maximise your milk quality
If milk is your livelihood, then a milk grade is your worst nightmare. As a proudly 100% NZ-owned and operated company, Agmax prides itself on being the go-to place to get yourself out of milk grade pickles, and better yet, help you prevent them.
We know the white stuff better than anyone.
