The 35-year-old woman, who has name suppression, wants the Accident Compensation Corporation (ACC) to pay for counselling for her post-traumatic stress syndrome, suffered after finding out her boyfriend had HIV but did not tell her.
The couple had unprotected sex throughout their four-month relationship, which ended in April 1996 when she learnt of his condition. She is not HIV-positive.
The woman took her case to the Christchurch District Court last year, but it was dismissed. She lost a High Court appeal last week.
The woman's lawyer, Wellington counsel John Miller, said he would continue to fight for the woman's right to counselling by taking the case to the Court of Appeal.
Miller said ACC had repeatedly refused to provide counselling for the woman because her situation did not involve sex violation or assault, but he argued his client was violated because she would not have consented to sex if she knew her partner was HIV-positive.
