Enrolment in a primary health organisation (PHO) is voluntary. Most New Zealanders are however enrolled through their general practice and gain the benefits associated with belonging to a PHO, which can include cheaper doctors’ visits and reduced costs of prescription medicines.

Enrolment information

Most general practices are now part of a PHO. If you are not sure whether your general practice is part of a PHO, you can ask your regular doctor or practice nurse.

To enrol, you will have to complete and sign a form which the doctor, nurse or medical centre receptionist will give you. The form will require you to provide some personal details such as name, age, date of birth, address and ethnicity. The information collected at enrolment is subject to the Privacy Act 2020 and the Health Information Privacy Code 2020, so the privacy of your information is protected.

Enrolment demographics

Information is available on the number of people who are enrolled in a PHO and the demographic details of enrolees by PHO, Lead District and District of Domicile. Download the latest pivot table of PHO Enrolment Demographics as of June 2024 [xlsx, 1 MB]

Monthly tables for prior financial years are collected in the relevant workbooks.

Access to Primary Care

The table below shows the estimated percentage of the total population who are enrolled in a PHO by ethnicity as of April 2024.

















The estimated coverage for a population is sometimes slightly more than 100% as the underlying population comes from Stats NZ population projections and the enrolment number comes from the primary care data collection. Detailed information on the number and percentage of the total population who are enrolled in a PHO for each of the 20 Districts can be found in the spreadsheets below. The information is presented by ethnicity, deprivation, gender and age group for each quarter since April 2019.


Note that updated population projections were used in the calculation of the January 2022 and January 2021 statistics. The updated projections use the latest subnational population estimates and updated methodology to calculate migration. The combined impact is a variation in projected population for some Districts when compared to releases prior to January 2021.
