SNOMED releases

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 300,000 clinical concepts and 1,000,000 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 approved subsets, maps, language reference sets and local concepts and terms we publish are made freely available to implementers in a quarterly release which is an extension to the SNOMED International Edition.

You can register and download the SNOMED International Edition and SNOMED NZ Extension from our SNOMED Member Licensing and Distribution Service.


The NZ Extension includes subsets for common terms related to smoking cessation, emergency care, cardiology, gynaecology, rheumatology, child health assessment, notifiable diseases and disability.

The NZ Extension includes maps for migrating from Read Codes to SNOMED in primary care and a map from the NZ Medicines Terminology by SNOMED.

The content of each subset and map will be governed by a recognised national clinical network.

Regular updates to the subsets and maps will include new content as it is developed.

We welcome your feedback and participation.
