About Te Rēhita, the National Register
Once a patient is diagnosed with breast cancer, their information is included in Te Rēhita, the confidential National Register.
This data is used for research, to audit care, to help plan breast cancer services, and to identify where further progress is needed to improve the lives of everyone affected by breast cancer, now and in the future.
- Te Rēhita Mate Ūtaetae, the Breast Cancer Foundation National Register, holds a rich database of over 38,000 patients who have been diagnosed with invasive and pre-invasive breast cancer between 2000 and 2021. Approximately 4,000 new patient registrations are added each year.
- Data on Te Rēhita, the National Register, has been collected since 2000 for use in research and audit to help improve diagnosis, treatment and outcomes.
- From 1 January 2020, Te Rēhita, the National Register, includes all patients diagnosed with pre-invasive and invasive breast cancer in New Zealand from Northland to Southland.
- Of the patients in these regions, more than 99% are included in Te Rēhita, the National Register (less than 1% opt out).
- New Zealand is a world leader in the collection of near-national data about advanced breast cancer (ABC) diagnosis and treatment. Source: BCFNZ Study into metastatic / advanced breast cancer.

How Te Rēhita, the National Register, data is used
Data from Te Rēhita, the National Register, is used for:
- Epidemiology and changing patterns of breast cancer
- Assessing efficacy and treatment of existing and new treatments
- Identifying regional and NZ-specific cancer trends
- Assessing and addressing inequities in care
- Indirectly enabling other research, e.g. clinical context for cancer genome research
- Healthcare planning
- Audits for quality measurement and improvement, e.g. BreastSurgANZ Quality Audit
Data from breast cancer patients in both public and private healthcare systems is collected from hospitals and health professionals by authorised data managers.
The more complete the data, the greater the value of Te Rēhita, the National Register, for improving treatment and care in the future. Therefore, patients are followed up all their lives. If needed, general practitioners (GPs) may also be contacted by an authorised data manager for annual follow-up data, including breast cancer medications prescribed and any recurrent or new breast cancers.
