Northland Seed and Supplies offers a range of services to make sure you are well catered for.

We have reps who travel around Northland to help clients with their pasture systems and crop management. We work with clients to formulate establishment plans, complete with supplying the products required, monitoring crops, and assisting with organising contractors.
