What is Demeter?

Demeter is a world wide certification system, used to verify to the consumers in over 50 countries that food or product has been produced by biodynamic methods. The Bio Dynamic Farming and Gardening Association is the certifier in New Zealand. (The Association registered Demeter as a certification trademark in 1984.) Inspectors visit the operators (farmers and processors) annually to collect information about their methods. A committee of assessors then decides whether to grant certification. Most committee members are experienced biodynamic farmers and/or processors. The Demeter Standards are a published statement of the allowed and the required practices for certified biodynamic operators. All persons working towards Demeter certification are recommended to obtain a copy from the Bio Dynamic Farming and Gardening Association’s office or download from the link at the foot of this page. Any questions they raise can be referred to the Association office.

How to get certification

Join the Bio Dynamic Farming and Gardening Association.


  • Learn and practise biodynamic methods on your farm.
  • Obtain a Demeter application pack from the Association’s office or download the various documents here (This link opens a new page with a number of different documents on it)
  • Obtain a copy of the Demeter production standards from the Association’s office or download here (This link opens a pdf copy of the standards which you can read or download)
  • Complete the application to request a visit from an adviser or inspector and begin the stand-down year.

The visit of the farm adviser is the most common starting point for formal progress towards certification which is followed by working to the published Demeter standards. This visit is one of the criteria for beginning the registration year. A formal inspection is an alternative starting point – the difference between the two staring points is explained in the application pack.


  • Obtain information about processing requirements from the Association office.
  • Submit a letter of application accompanied by a detailed description of proposed processing methods.

Some requirements for processing

  • Raw produce certified Demeter or In Conversion to Demeter.
  • Appropriate processing methods to preserve biodynamic quality, as detailed in the Demeter International Processing Standards.
  • Fail safe systems to prevent mixing in of uncertified produce. (This is just an outline.)

  • Supporting documents such as declarations from merchants and other farmers from whom supplies have been obtained
  • A farm profile – details of farm physical characteristics such as soil type, climate etc written according to the Demeter NZ template

If a year or more of inspection or reporting is missed, the Association reserves the right to require extra information and fees or to withhold certification until an acceptable continuous history of inspection is re-established. Full Demeter certification is normally required for exporting.
