Tēnā koe Jim,
Your Official Information Act request, reference H2022013384:
Thank you for your email of 25 September 2022 requesting information relating to respiratory
related deaths and hospitalisations.
As part of the health and disability system reforms, as of 1 July 2022 the functions previously under
the Manatū Hauora Data & Digital directorate have transferred to Te Whatu Ora Health New Zealand
(Te Whatu Ora). As the matters you have raised now fal under the functions of Te Whatu Ora, our
agency will respond to your request which has been considered under the Official Information Act
1982 (the Act). You requested the fol owing:
please provide the total figures for all non-COVID respiratory related deaths and hospitalisations
from 1st January 2018 until 1st September 2022 broken down by month.
While Te Whatu Ora is able to provide hospitalisations for respiratory illnesses, it is difficult to
separate this into COVID-19 and non-COVID-19 related respiratory illnesses. Please keep in mind that
not all COVID-19 hospitalisations are classified as respiratory disease. For example, if a patient with
COVID-19 has a heart attack and is hospitalised (with COVID-19 being incidental), this would not be
classified as a respiratory event.
In addition, the presence of a COVID-19 code linked to a hospitalisation does not necessarily mean
that the respiratory diagnosis was related to COVID-19. We are unable to assume the causal link
between these two factors. For example, a patient might contract COVID-19 during their stay for
another, different respiratory disease.
Because of this, Te Whatu Ora cannot easily identify non-COVID-19 respiratory hospitalisations from
the data and information currently held. While the Act al ows New Zealanders to ask for information
from Ministers and government agencies, there is no requirement for agencies to create new
information or compile information they do not hold. Therefore, your request has been refused
under section 18(g) of the Act, as the information is not held by Te Whatu Ora.
Please find two tables attached as Appendix 1. Table 1 provides deaths caused by respiratory disease
in 2018, broken down by month. Table 2 provides discharges from publicly funded hospitals coded to
respiratory disease (including COVID-19), from January 2018 to August 2022, broken down by month.
The data in Table 2 for 2021 and 2022 is currently provisional and may be subject to change.
Table 1 denotes deaths that were registered in 2018 – patients who died in December 2018 may not
have been registered until 2019 and would therefore not be included in the data provided.

More recent mortality data is not currently available. After the close of a calendar year, there is a 12–
18-month process to assign cause of death codes to most deaths in that year. The Ministry’s clinical
coding team reviews the death certificate and health history of the deceased, to assign cause of
death codes. Approximately 10% of deaths are referred to the Coroner each year to determine
cause. Deaths that require a coronial inquiry can take 2-3 or more years for cause of death to be
assigned. We do not make mortality data available publicly until the majority of deaths have been
assigned a cause of death, so that the data we release is complete and accurate. The Chief Coroner
has noted delays in the time it is taking them to assign cause of death codes.
I trust the information provided is of assistance. You are advised of your right to also raise any
concerns with the Office of the Ombudsman. Information about how to do this is available at:
www.ombudsman.parliament.nz or by phoning 0800 802 602.
