Introduction

Health New Zealand | Te Whatu Ora works with health agencies and their industry partners to develop SNOMED CT® reference sets, maps, language reference sets and other content for digital health solutions in Aotearoa New Zealand.

The SNOMED CT New Zealand Extension packages these components for release every April and October, to be used with the latest designated SNOMED CT International Edition release.

The content can be downloaded from our member licensing and distribution service, viewed online using the SNOMED CT browser or accessed via a standard FHIR® API using the NZ Health Terminology Service

We welcome your feedback and participation. For more information about SNOMED CT implementation in New Zealand, email standards@tewhatuora.govt.nz, visit our website or join the standards channel at ehealthforum.nz.

Background

This document summarises the content changes included in the April 2025 production release of the SNOMED NZ Extension package.

It also includes technical notes detailing any known issues.

This SNOMED NZ Extension package is dependent upon and should therefore be consumed in conjunction with the SNOMED CT International Edition February 2025 release.

New and updated content

The April 2025 release includes updates to the previously released content in the SNOMED NZ Extension and introduces some new content.

This release includes new content in the following areas.

Gambling harm intervention reference set

This reference set has been developed to support the collection and reporting of gambling harm intervention data as specified by draft standard HISO 10112:2025 Gambling Harm Intervention Data Standard.

Health service type reference set

This reference set has been updated in partnership with Healthpoint to extend the SNOMED CT content available for the health directory services used by consumers, health professionals and helplines.

Patient friendly terms

The set of patient friendly terms in NZ English and Te Reo Māori for health service types has been further extended in partnership with Healthpoint and Te Taura Whiri i te Reo Māori | Māori Language Commission.

Emergency care reference sets

The chief presenting complaint and diagnosis reference sets have been updated as a result of the latest six-monthly review in February 2025.

CanShare reference sets

Te Aho o Te Kahu | Cancer Control Agency has developed a collection of CanShare reference sets for New Zealand and this content has been further extended in this release. These reference sets provide standard sets of SNOMED CT concepts to use for recording, sharing and querying cancer data in Aotearoa. Each concept in these reference sets has a preferred term in the CanShare language reference set (SCTID 231621000210105), selected by New Zealand clinicians to standardise the way that cancer data is displayed . These reference sets support a range of cancer data, including key diagnostic components, treatment plans, national registers and screening programmes.

The April 2025 release includes 53 new CanShare reference sets, 115 updated reference sets, 459 static reference sets and 443 new concepts in the following areas:

  • Cancer streams, sub-streams and primary cancer types to support clinical workflows for medical oncology and haematology.

  • Topographies for recording the primary site of a cancer. This includes a maximal set of body sites, a high-level set of commonly used body sites, and body sites specific to breast, thoracic, gastrointestinal, female genital, genitourinary, soft tissue & bone, skin, head & neck, central nervous system, endocrine & neuroendocrine, and eye cancers.

  • Lymph nodes for recording a lymph node site (for pathology or surgery) for breast, thoracic, gastrointestinal, female genital, genitourinary, head & neck, and eye cancers.

  • Cancer histologies for haematologic, breast, thoracic, gastrointestinal, female genital, genitourinary, soft tissue & bone, skin, head & neck, central nervous system, endocrine & neuroendocrine, eye, and paediatric (new) cancers, based on the WHO Classification of Tumours 5th edition.

  • Grading systems for haematology and solid (new) cancers.

  • Staging systems (AJCC and non AJCC) for haematology and solid (new) cancers, including clinical, pathological, and a subset of recurrence or retreatment, and post therapy or post neoadjuvant therapy staging.

  • Prognostic scoring systems for haematology, female genital, and genitourinary (new) cancers.

  • Neoadjuvant therapy response scoring systems for breast, colorectal, and female genital cancers.

  • Specimen collection procedures and specimens to support all cancer types.

  • Ancillary study tests and results for a wide range of cancers, to support testing eligibility for new cancer medicines (new), as well as breast and colorectal (new) cancers.

  • Additional data to support radiation oncology and systemic anti-cancer therapy treatment plans, radiation oncology waitlist data (new) and national screening programmes eg, national cervical screening programme (new).

Systemic anti-cancer therapy regimens

Further concepts representing systemic anti-cancer therapy regimens have been added to support the CanShare programme.

Other changes

Fifteen reference sets have been updated to replace inactive concepts with the active concepts.
