National Maternity Collection

The National Maternity Collection (MAT) provides statistical, demographic and clinical information about selected publicly funded maternity services up to nine months before and three months after a birth.

MAT contains data on primary maternity services provided under Section 88 of the New Zealand Public Health and Disability Act 2000. MAT also contains inpatient and day-patient health event data during pregnancy, birth and the postnatal period for mother and baby, sourced from the National Minimum Dataset (NMDS).

MAT is used by the Ministry of Health, DHBs, PHOs, clinicians, researchers and members of the public.



The National Booking Reporting System (NBRS) provides information by health speciality and booking status on how many patients are waiting for treatment, and also how long they have had to wait before receiving treatment.


NBRS contains details of all booking status events involving a healthcare user who:

  • receives a priority for an elective medical or surgical service, and
  • is likely to receive publicly funded treatment.


Information is collected about their date of entry into the system, their assessed priority, and their booking status.

Start date

Hospitals have been required to report data since 1 August 2000.

Guide for use

Booking status information can be linked by unique event identifier (Booking Entry ID) to the actual procedure when it is undertaken. Using this identifier, records in the NBRS may be linked to the NMDS, which contains data about inpatient and day patient events.

Security of data

The NBRS database is only accessed by authorised Te Whatu Ora staff for maintenance, data quality, analytical and audit purposes.

Authorised members of Te Whatu Ora Elective Services Team have access to the data for analytical purposes via the Business Objects reporting tool and the secure Health Information Network. Business Objects contains a subset of the data described in the Data Dictionary.

Privacy issues

Te Whatu Ora is required to ensure that the release of information recognises any legislation related to the privacy of health information, in particular the Official Information Act 1982, the Privacy Act 1993 and the Health Information Privacy Code 1994.


Information available to the general public is of a statistical and non-identifiable nature. Researchers requiring identifiable data will usually need approval from an Ethics Committee.

National reports and publications

Summary NBRS data is published on the elective services web site as part of the Elective Services Patient Flow Indicators (ESPIs), and regular data quality reconciliation reports are available to Districts.

Data provision

Customised datasets or summary reports are available on request, either electronically or on paper. Staff from Te Whatu Ora Analytical Services team can help to define the specifications for a request and are familiar with the strengths and weaknesses of the data.

Te Whatu Ora Analytical Services team also offers a peer review service to ensure that Te Whatu Ora data is reported appropriately when published by other organisations.

There may be charges associated with data extracts.
