TNZ Growing Products is a Southland company with branches in Invercargill, Nelson and Auckland. We are focused on producing quality peat and bark products for wholesale to the horticulture and landscaping industries within New Zealand and Australia.

Taken almost exclusively from milled-for-timber Pinus Radiata trees, all our bark is a natural and environmentally friendly product.

Located in Southland, New Zealand, our company proudly owns and manages our peat resource. This enables us to select the right grade of peat for each customer's requirements.

All of our potting and growing media mixes are peat and bark-based and custom manufactured to each customer's requirements. 

If you're looking to maximise growth of your produce then our composts are the easy and natural choice.
