A law firm representing women who may have contracted Hepatitis C from a doctor working at a Melbourne abortion clinic says its clients feel betrayed.
Australian authorities are investigating a doctor who has the disease and worked at the clinic.
They are also contacting 3500 women, including 55 from New Zealand, who were patients at the Croydon Day Surgery centre between January 2006 - December 2009.
The Ministry of Health in New Zealand started tracing them on Tuesday.
The law firm Slater and Gordon in Victoria is acting for a number of women who are infected with Hepatitis C.
Spokesperson Paula Shelton says it is a double-blow for the women, who made a difficult decision to go through a traumatic procedure.
New Zealand patients can ring Healthline on 0800 611 116, which will put them through to the Hep C line in Victoria for advice, and details of testing.
