The Ministry of Health is working with the health and disability sector to develop SNOMED subsets and maps for digital health solutions in New Zealand.

SNOMED CT is a system of terminology consisting of over 340,000 clinical concepts and 1,200,000 terms. SNOMED subsets enable the findings, diagnoses, conditions, procedures and other concepts commonly used in any particular health domain to be easily and consistently recorded at point of care. Maps between SNOMED and other terminology and classification systems are also needed for some purposes as health providers and their industry partners implement SNOMED in frontline systems.

The New Zealand subsets, maps, language reference sets and local concepts and terms published are freely available to implementers in releases of the SNOMED NZ Edition every six months.

The SNOMED NZ Edition includes all content from the SNOMED International Edition and New Zealand specific content in a separate package called the SNOMED NZ Extension.

Register as an affiliate user and download the SNOMED NZ Edition from the New Zealand SNOMED Member Licensing and Distribution Service.


The SNOMED NZ Edition is a comphrehensive source of concepts and terms for recording health information.

The New Zealand National Release Centre creates SNOMED subsets for terms belonging to a health specialty, service type or domain where this can be useful for end users and implementers. For many purposes, subsets are not required and the user can use the SNOMED International content directly.

All local content will be governed by a recognised national clinical network.

We welcome your feedback and participation.
