The Ministry of Health says more than half of the 56 New Zealand women at risk of contracting Hepatitis C at an Australian clinic are clear of the disease.
All the New Zealanders tracked down and tested so far have returned negative results.
Victoria's health department says 35 patients out of 3,5000 have been directly linked to a doctor who practised at the Croydon Day Surgery in Melbourne.
The doctor, who tested positive to the virus, was suspended from the practice in February this year.
The health ministry still wants to talk to any New Zealand women who may have visited the surgery between January 2006 and December 2009.
