Dear E
Official Information Act Request for – Orthognathic Surgical Criteria
I write in response to your Official Information Act request received by us 1st October 2021, you
requested the following information:
•
I am writing to request a report on how many patients have been provided with publicly
funded orthognathic surgery each year, over the past 5 years from Counties Manukau DBH as
a total number. I would like this number to then be categorised into how many patients
received orthognathic surgery for a Class I I Malocclusion (Child and adult categorised).
•
Additional y, I would like to be provided with a list of the Cephalometric and OPG- X Ray
measurement criteria that would qualify an adult patient with a Class II Malocclusion to
receive publicly funded Orthognathic surgery (+/- Community Services Card).
•
Lastly, I would like to be provided with a list of the criteria that establishes the waiting times
for an adult requiring orthognathic surgery.
Counties Manukau Health Response:
For context Counties Manukau Health (CM Health) employs over 8,500 staff and provides health and
support services to people living in the Counties Manukau region (approx. 601,490 people). We see over
118,000 people in our Emergency Department each year, and over 2,000 visitors come through

In both tables 1 and 2, we have withheld the information where the numbers are equal to or
less than 3 under section 9(2)(a) of the Official Information Act 1982, as withholding of the
information is necessary to protect the privacy of natural persons, including that of deceased
natural persons. We have considered whether the public interest outweighs the need to protect
the privacy of individuals and have determined that it does not.
