HL7 New Zealand – Autumn 2023

29 March 2023 Comments Off on HL7 New Zealand – Autumn 2023 By admin


The latest version of the HL7 FHIR standard (R5) was published on March 28th. Although it contains no new normative content, and is technically a trial release, there are a significant number of new resources (giving an overall total of 158) and the maturity level of many of the most-commonly used resources has increased. We would be happy to discuss the potential use of this new release within New Zealand with potential implementers as well as receiving feedback from the broader community on the roadmap for the next major release (R6).

For those continuing to use Release 4, please note that version of the specification is now available at The R4B sub release can be found at


Towards the end of last year, we published the second version of the HL7 FHIR NZ Base Implementation Guide. This was the result of many months of diligent work by our HL7NZ FHIR® Implementation Work Group, with broad sector representation. 

This Guide contains the base FHIR implementation rules for New Zealand (Extensions, Profiles, Identifiers, and Terminologies). It is an ‘abstract’ artefact from which all other FHIR Implementation Guides in New Zealand may be derived, and we hope that it will continue to be a valuable resource for the local FHIR community.

As it is a ‘living’ artefact, work on the next version commenced last month, and the Work Group continues to hold regular, one-hour meetings on Fridays at 12:00pm. All interested parties are welcome to attend these meetings – further details are available on our Web Site

In response to questions we receive about FHIR adoption in Aotearoa New Zealand, we recommend these sources of information…

Kiwis on FHIR on our Web Site – all additions and updates gratefully received!

Chairman’s Xmas Message 

20 December 2022 Comments Off on Chairman’s Xmas Message  By admin

Kia ora and happy holidays 2022 from HL7 New Zealand

It’s my great pleasure to wish you a happy, peaceful and prosperous end-of-year holiday season.
Christmas is almost here! As your newly elected HL7NZ Board Chair, I’ve been doing more than my usual share of reflecting on the year just wrapping up and the one about to begin. Clearly, we live in fast-moving times for health information standards development and implementation. HL7 FHIR is really taking off as the new lingua franca for sharing clinical, financial, and administrative data around the sector. Its importance has been recognised by many governments including our own, by vendors large and small, and by the thousands of implementers who contribute to the standard’s ongoing development. And FHIR isn’t even done yet! Version 5 is in the balloting process, and it will be a few more years before we see Version 6. All going well, I think we can expect FHIR Version 6 to really be ‘done’.
I got to attend the HL7 International Working Group meeting in Baltimore last September. I saw an organisation revitalised by the return to in-person meetings, the election of a new slate of directors bringing fresh ideas, and the growing importance of FHIR Accelerators, where like-minded stakeholders work together (and provide the necessary funding) to solve real-world problems using FHIR. Importantly for us in NZ, HL7 International has expanded its Board to create new seats for non-US members. This will help ensure that the group’s mission and our needs as Affiliates don’t get lost behind the sheer size of the US contingent.
Here in New Zealand, we’ve been busy building and localising the FHIR artifacts needed to support our local implementers. The second iteration of the NZ FHIR Base Implementation Guide was published in the spring, and the HL7NZ FHIR Working Group is already stuck into the next release. Major FHIR implementations — live and still in the planning stage — in both the public and private sector signal that the disparate pieces of our health data ecosystem are joining up more and more each month.
Much of our momentum comes from our members, spanning public, private, and NGO enterprises. 2022 has seen the publication and updates of FHIR projects from Te Whatu Ora | Health NZ, Te Aho O Te Kahu | Cancer Control Agency, WebTools, MedTech, HealthPoint, Clanwilliam Health, and so many more. In the coming year we’ll be sharing more of these good news stories. After more than a decade of hard work by our past Chairs Peter Jordan and David Hay, it feels like we don’t really have to explain what FHIR is, what HL7 is, any longer. Instead, we get to help connect the dots so that NZ grows and keeps the workforce and the spirit of innovation that will allow continued progress on the difficult problems faced by our health system.
I feel extraordinarily privileged to follow in Peter Jordan’s footsteps as HL7NZ Board Chair. He’s built a smooth-running organisation, recruited a fantastic Board of Directors, and grown membership to its highest ever levels. Thank you for all the mahi you’ve put in! Luckily, he’s stayed on as Secretary so the sage advice he’s given me and so many in the sector will still be just a phone call away. We’ll all miss the cheery presence and seemingly effortless coordination of our past Secretary Linda McKay, who served in that role for 20 years and is moving to the next phase of her career.
On behalf of the entire HL7NZ Board, please again accept our very best wishes for you and your whānau this holiday season. I look forward to working with you in 2023.
John Carter
Chair, HL7NZ

NZ Work Group News

21 October 2022 Comments Off on NZ Work Group News By admin

We have just published the second version of the HL7 FHIR NZ Base Implementation Guide. This is the result of many months of diligent work by our HL7NZ FHIR® Implementation Work Group, with broad sector representation, and passed the required Membership Ballot, held last month, with flying colours. 

This Guide contains the base FHIR implementation rules for New Zealand (Extensions, Profiles Identifiers, and Terminologies). It is an ‘abstract’ artefact from which all other FHIR Implementation Guides in New Zealand may be derived, and we hope that it will continue to be a valuable resource for the local FHIR community.

We would also like to extend our gratitude to our members at Spark Health for kindly hosting the Guide.

Ballot on HL7® FHIR® New Zealand Base Implementation Guide 2nd Version

31 August 2022 Comments Off on Ballot on HL7® FHIR® New Zealand Base Implementation Guide 2nd Version By admin

The  HL7 New Zealand FHIR Implementation Work Group invites you to participate in a ballot on the second version of the HL7® FHIR® New Zealand Base Implementation Guide. This FHIR R4 Resource contains the base FHIR implementation rules (notably extensions, profiles, identifiers, and terminologies) for New Zealand. It is an ‘abstract’ artefact from which other FHIR Implementation Guides in this territory may be derived. It is intended to be a ‘living’ artefact that will be enhanced and maintained, based on feedback and usage experience from the FHIR Implementation Community mainly, but not restricted, to within New Zealand.

What is an HL7 Ballot?

Balloting is the mechanism used by HL7 to allow the wider community to make comments on HL7 Standards and Implementation Guides, and for those comments to be reviewed by the authors, making updates as required. It is a mechanism to ensure fitness for purpose and broad consensus, via the following process…

  • There is a specific period during which comments are solicited (the ‘Ballot Period’) which is from Monday 29th August 2022 to Monday 12th September for this ballot.
  • A copy of the balloted artefact is made that will remain unchanged over the Ballot Period. This is the copy against which participants make comments.
  • Anyone can make a Ballot Comment, simply by adding a GitHub Issue(instructions below) to the repository where the Implementation Guide is stored.
  • All comments are reviewed by the Authors in an open Work Group meeting. Each comment will have an outcome (a ‘Disposition’) which may or may not result in changes to the Implementation Guide, after which the issue is closed. The outcome is recorded as a comment against the issue, including any rationale for the outcome, which anyone can view.
  • Anyone can attend the review meetings (and are encouraged to do so), but only current HL7 New Zealand (HL7NZ) members can vote on the Disposition.

Where is the Implementation Guide?

The Ballot Version of the Implementation Guide (‘NZ-Base’) is located here.  In the first version, NZ-Base was primarily a collection of extensions which this version augments. The major new class of additional content in this version are profiles, which are listed on the ‘profiles’ tab. Clicking on the profile name in the first column will load the detailed description of that profile’s definition. This is generated by the standard HL7 FHIR build process and has the same format as the core FHIR specification. 

How to make Ballot Comments

Comments (Issues) are recorded against the source of the Implementation Guide, which is a GitHub Repository located hereIssues are on the Second Tab of the Repository.

  • Firstly, you will require a GitHub Account. If you don’t already have one, then go to GitHub, and click the ‘Sign up’ link to the upper right and follow the instructions from there.
  • Next, browse to the Issues Page of the HL7NZ Base Repository 
  • To the right (above the current list of issues) is a green button labelled ‘New Issue’. Click that, and the new issue dialog will appear. 
  • Each issue has a title and a description…
  • Enter a meaningful title for the issue. For example, “The description of ‘date of death’ is unclear, or ‘there is a typo in the description of ‘additional authorisation’.
  • In the description field enter the remaining details. Please include the URL of the extension definition page that you are commenting on. The contents will depend on the nature of the comment – if you are commenting on text, include the suggested text and where it applies.
  • There are also labels you can apply if you so wish, but these are not mandatory.
  • You can also elect to set up a Notification, so you are alerted to any activity on your issue. Details here
  • Examples of comments…
  • Suggested text to make the meaning of an Extension Definition clearer
  • A comment about the contents of an extension – for example additional elements that may be useful
  • A comment about the datatype of an extension – is there a better one that should be used?
  • A comment about the terminology used to define the contents of a coded element.
  • Push back against the extension itself – should it even be included? Is there an existing one that could be used instead, or is there already a core element on the resource?

Please note that only comments made against the current contents of the Implementation Guide will be considered as part of this ballot. Any suggestions for additional content, such as extensions or profiles will be deferred until the next release.

What happens to Ballot Comments after Submission?

Anyone can make a comment against your Issue (that’s why notifications may be helpful) but only the HL7NZ Work Group can determine what happens to it (the ‘Disposition’ of the Comment). This Group meets weekly (Friday at 12 noon via ZOOM) and will consider open comments. Anyone is welcome to attend and participate in the discussion, but only HL7NZ members can vote on the Disposition. Send an Email  if you require our contact details. We can’t guarantee to discuss any specific issue on a particular date as this will depend on the number and complexity of comments.
This is an open, community-based, review process with complete transparency of the deliberations and the outcome. Anyone can create issues or make comments against existing ones. However, only HL7 NZ members can participate in the Disposition Vote and once made, that decision is final.
If you have any questions about this process, please contact us here.
Happy Balloting!
HL7 New Zealand FHIR Implementation Work Group

Winter 2022 Update

23 June 2022 Comments Off on Winter 2022 Update By admin

Kia ora koutou,

In our last update, we provided a basic outline of the agreed release plan for the next two major versions of HL7 FHIR. We can now announce that a new revision of the current R4 version (R4B) has been published and is now the current version of the Standard available at A full explanation of R4B and the changes from R4 can be viewed here.

We would be delighted to hear from any of the New Zealand Implementer Community who are planning to use R4B, particularly any of the new or changed Resources. HL7 New Zealand will decide on whether to upgrade the Terminz FHIR Server soon. This presently holds most of the local conformance resources and is gaining use as a Test Service for our Members, something we are looking at progressing with our key partners at the  Digital Health Association and their Digital Interoperability Industry Group.


The HL7NZ FHIR® Implementation Work Group is continuing work on the second version of the Base NZ FHIR Implementation Guide. The current focus is on NZ profiles on data types, such as Address, and key resources such as Patient; however, we are also continuing to encourage requests for extensions that have a national scope. Weekly meetings are at 12:00 pm on Fridays.  All interested parties are welcome to attend these meetings – further details are available on our Web Site


After nearly 3 years of virtual events, we are delighted that HiNZ is now planning to hold an in-person Digital Health Week NZ 2022 in Rotorua from 5-8 December. This will include our long-awaited joint workshop with HISO – Escape from Burning Platforms with SNOMED on FHIR

In the meantime, we are planning to re-commence our programme of Webinars in which our members showcase their implementations of HL7 FHIR. If you would like to present one of these sessions, please contact us. Later in the year, we are also hoping to provide another joint FHIR Connectathon with HL7 Australia.

Ngā mihi
