This standard is a dataset specification for the patient and consumer identity and demographic information recorded in the National Health Index (NHI) and the administrative and clinical information systems used by New Zealand health providers.
2019 revision of the standard
NHI numbers in the current format will run out by 2025, and numbers issued after this point will have a new format. The standard has been revised to provide details of the chosen new NHI number format. Systems should be changed to accommodate the new format by July 2022. We are providing for this now to allow plenty of time for changes to be made.
A change to the language code set, to recognise all Pacific Island languages, is the other change in this revision.
The above completes work agreed in 2018 when the Ministry sought feedback on possible changes to the NHI data set and this standard. The published summary included a recommendation to improve the recording of gender identity, and this is our next step.
The standard already allows for male, female and other, or gender diverse, to be recorded using the level 1 classification of the gender identity standard published by Stats NZ. The NHI system will add the capability to record gender diverse in this way within the next 12 months. The patient/consumer may also supply their own free text description if they do not identify as male or female.
We will continue to participate in and follow the further work on recording sex and gender outlined by Stats NZ and update our standard once any changes are formalised.
