Health Information Standards Organisation (HISO) operates under Standards New Zealand to convene the national mirror committee for the ISO/TC 215 Health informatics technical committee of the International Organisation for Standardisation (ISO).

We received nominations from the sector and our proposal to form the national mirror committee was ratified by the Standards Approval Board in March 2021.

The Standards Approval Board is an independent statutory board set up under the Standards and Accreditation Act 2015. The Board commenced in March 2016 and is responsible for approving the membership of standards development committees and standards that are developed by these committees.

Being a participating member allows us to have input to international data and digital standards that can be adopted in New Zealand to improve our health and disability system.


The ISO/TC 215 Health informatics national mirror committee has responsibility to:

  • Monitor all ISO/TC 215 work items, drafts and ballots
  • Review the technical content of documents out for comment and formulate a national position
  • Inform Standards NZ of the position reached on ISO/TC 215 work proposal (NP), committee draft (CD), draft international standard (DIS) and final draft international standard (FDIS) documents
  • Work with Standards NZ to enter a vote on all NP, CD, DIS and FDIS documents
  • Provide a valid technical justification for any negative vote
  • Inform Standards NZ of the position reached on ISO standards under systematic five-year review
  • Consult with stakeholders in forming a national position on international matters

Dr Koray Atalag


Koray is a medical doctor with a PhD in Information Systems and a Fellow of the Australasian Institute of Digital Health (FAIDH). Having significant experience in digital health, in particular electronic health records (EHR) and interoperability, he is passionate about making ICT reach its full potential in healthcare. Koray serves as CIO and Chief Scientist at The Clinician, a health IT company, that has created an interoperable platform to engage patients, collect patient reported outcome/experience measures (PROMs and PREMs) to create actionable insights and drive value-based care.

Koray holds an honorary academic appointment as senior research fellow at the Auckland Bioengineering Institute of the University of Auckland. His main research areas are electronic health record and interoperability standards, clinical decision support systems and computational physiology. Koray taught the Healthcare Decision Systems course (HLTHINFO 730) as part of the Postgraduate Diploma in Health Informatics Programme at the University of Auckland and supervise Masters and PhD students.

Having been deeply involved in HL7 and openEHR (a global health informatics standards for electronic health records and interoperability), Koray seeks to improve software maintainability and enable interoperability by tackling the complexity and changeability of health information using computable models – called Archetypes.

Koray co-authored the New Zealand Interoperability Reference Architecture, published as a HISO standard in 2012, and led technical evaluations of major health IT innovation projects. He has served as an elected member of the openEHR Foundation Management Board, past vice-chair and now an HL7 New Zealand Board member.

Samuel Wong

Samuel is VP Products at Vensa Health and co-chair of the NZHIT Virtual Health Industry Group.

Samuel Wong has been involved in the healthcare sector for over 20 years. His experiences in health informatics and health standards spans across a wide range of sectors covering clinical record management in hospitals, and working in senior analytics lead or data governance/architect roles in primary health organisations, national emergency ambulance services, and national telehealth services. Supplementary projects also involved data collaborations with most of the directorates at the Ministry of Health, ESR, R&D in Medtech/Biotech industry and most recently, joining the Health IT industry. His current role is the VP Product Innovations at Vensa Health, one of the national patient portal providers.  In addition, he also serves as the Chair of NZHiT’s Virtual Health Industry Group, and part of the NZ Telehealth Leadership Group. 

In his various roles, Samuel has been accustomed to managing and advocating health information standards, in trying to create interoperability between various systems for patient care and health system management purposes. Understanding care of a patient has to involve the use of clinical terminologies, like SNOMED CT, related codes such as NZ Formulary, NZULM and Pharmacode, or diagnostic/procedure codes found in ICD-10-AM, READ and LOINC. Patients also require standards to describe occupations, ethnicities, industries, identity and gender/sexual orientation. Through his senior roles, he was also completed training on service provisions for quality (e.g. ISO9001, ISO13485) as well as national/international privacy standards and sector-wide data governance. The range of integration between understanding these standards has helped provide opportunities for using data towards AI-based contextual learning models to improve care pathways which is in line with the direction of ISO/TC 215.

Samuel has attained a BSc (Biomedical Sciences) and a PGDipSci (Medical Sciences) at the University of Auckland. For clinical practice, he has qualified for the National Diploma in Ambulance Practice. In 2018, he completed the LEAD:Corporate Innovation Certificate from Stanford University.
