Bald New Zealanders may have been exposed to HIV and other infectious diseases at an Australian hair replacement clinic.
Dr Angela Campbell's clinic in Sydney was found by Australian authorities to have poor infection control practices, including problems with the cleaning and sterilisation of surgical instruments and equipment.
A Ministry of Health spokesman said estimates of patient numbers in Australia were only in the hundreds, so the number of New Zealanders potentially affected was expected to be relatively low.
The treatment involved cutting hair from one part of the head and transplanting it into another part.
Patients who underwent treatment between December 2010 and February 2013 could have been exposed to blood borne infections such as HIV or hepatitis B and C.
The Ministry of Health recommended individuals who attended the clinic contact Healthline free on 0800 611 116 for advice and assistance in contacting the Australian Public Health Unit involved in tracing patients of the clinic.
