A Tool Kit for: NZS4454: 2005 – The New Zealand Standard for Composts, Soil Conditioners and Mulches (2007)

This tool kit was conceived and managed by CompostNZ (a WasteMINZ sector group).

The NZS4454 applies to organic products and mixtures of organic products that are to be used to amend the physical, biological and chemical properties of natural or artificial soils and growing media.

It specifies physical, chemical, biological and labelling requirements for composts, mulches, soil conditioners and related products that have been derived largely from compostable organic materials and which meet the minimum requirements as set out in this Standard. It covers materials marketed or distributed both in bags and in bulk.
