Cannabis, including industrial hemp varieties, can be used to make a range of dietary, cosmetic, and medicinal products. These range from medicinal cannabis extracts through to hemp seed oils, hemp ‘milks’, and hemp protein powders. Some of these products are already in the market while others are in active development following recent legislative changes in New Zealand.

This workshop will give an overview of typical product characteristics and current product trends, followed by a more detailed discussion on the processing techniques used and regulatory requirements in New Zealand for manufacture of these products. The workshop will be followed by a tour of supercritical fluid extraction, mixing, blending, and drying operations located at The FoodBowl.


  • Overview of the hemp/cannabis plant and product opportunities derived from it
  • Overview of licensing and regulatory requirements for handling different plant varieties and manufacturing different classes of products
  • Medicinal cannabis products:
  • Product characteristics
  • Extraction, decarboxylation, concentration of cannabinoids
  • Current trends in R+D and new product development
  • Hemp seed products:

  • Hemp protein products, including hemp ‘milks’ and powders
  • Facilities tour

Please note that hemp fibre products represent a further industrial processing opportunity but are not directly discussed in this workshop.
