Dairy products

If you process or handle dairy products you need to meet requirements to protect the industry, consumers' health and our reputation overseas. Find out about our requirements for dairy processors and handlers.


We're still working on this section of the new website. When complete, it will provide information to support dairy processors and handlers. In the meantime, use these links to find relevant information:

Dairy processors and milksolids reporting

Accurate information is needed from dairy processors to determine whether the market share thresholds set out in the Dairy Industry Restructuring Act 2001 (DIRA) are met.

Processors must provide this information when requested by the Minister for Primary Industries. When you get the Minister's letter, complete the Dairy cow milksolids collection form. Or you can use the online questionnaire.

Use the form

When you receive the Minister's request for information, send a copy of the form by either:

Or complete the questionnaire

If you prefer, you can supply the information using our online questionnaire rather than the form.

What the information is used for

The DIRA has provisions to promote efficiency and contestability in New Zealand dairy markets. These expire when there is sufficient competition in dairy markets. The information that processors provide is used to assess whether this threshold has been met – when independent dairy processors have collected 20% or more of milksolids, on or from dairy farms (section 147(1) of the DIRA). There are separate thresholds for the North Island and the South Island and one or both thresholds may be triggered at any time.

The information processors provide also informs MPI's process to allocate dairy export licenses under the DIRA.

Who to contact

If you have questions about dairy processing or the dairy cow milksolids form, email info@mpi.govt.nz.
