Your Official Information Act request reference: HNZ00009495
Thank you for your email on 10 January 2023, asking for the following information which has
been considered under the Official Information Act 1982 (the Act). Please see outlined below
a response to each part of your request.
“Could you please supply the following information which could be sourced from your maternity
claims data. Monthly Data from 01/01/19 through to 31/12/22

Spontaneous Miscarriages
Te Whatu Ora does not have complete information about the number of spontaneous miscarriages
in New Zealand. We receive records from hospitals when someone is admitted and requires
treatment for a miscarriage. However, many people do not require hospital-level care for a
miscarriage. This means the information we could provide about miscarriages would not be
complete. As such, I am unable to provide data for spontaneous miscarriages under section
18(g)(i) of the Act as the information is not held by Te Whatu Ora or any other agency subject to
the Act.

Ectopic Pregnancies
•
Molar Pregnancies
•
Live Births
•
Perinatal Deaths
•
Neonatal deaths (First 28 days of Life)
•
Stil births (20 Weeks or> 400 g)”
The number of ectopic pregnancies, molar pregnancies, live births, stil births and neonatal deaths
that were reported to Te Whatu Ora each month from 2019 to 2021 are shown in the tables below.
The information provided in Table 1 and 2 was sourced from the National Minimum Dataset
(NMDS). The maternity datamart provided the information for Table 3 and 4, whilst the information
in Tables 5 and 6 was sourced from the mortality datamart.

When considering the data, it is important to note:
• The maternity and mortality datamarts currently only provide data up to 2020. More recent
information is not yet available.
• The NMDS currently contains complete maternity data up to and including 2021.
• As the hospitalizations data (NMDS) is a count of discharges, patients who have been
hospitalized more than once (due to transfers, readmissions, or repeated incidents) are
recorded each time, and wil appear in the data more than once.
If you have any questions, you can contact us at
[email address].
If you are not happy with this response, you have the right to make a complaint to the
Ombudsman. Information about how to do this is available at
www.ombudsman.parliament.nz or

As this information may be of interest to other members of the public, Te Whatu Ora may
proactively release a copy of this response on our website. Al requester data, including your name
and contact details, wil be removed prior to release. The released response wil be made available
on our website.
