A gay rights group is challenging the New Zealand Blood Service's ban on sexually-active homosexual men giving blood.
Queer rights group Rainbow Wellington complaint against the ban will be heard by the Human Rights Commission in February, The Press reported.
The group is challenging the blood service's prohibition of any man who had engaged in protected or unprotected anal or oral sex with another man over the past five years from giving blood.
The ban had changed since a 2007 review, before which any man who had engaged in homosexual acts over the past decade was banned from giving blood.
Rainbow Wellington chairman Tony Simpson said the ban was discriminatory.
"We say five years is too long, and in practical terms there's no difference between that and 10 years," he said.
"There's very little evidence, if any, that oral sex is a source of HIV-Aids infection, and we say sex with a condom is probably about as safe as you could get."
New Zealand Blood Service spokesman Paul Hayes said the safety of the blood supply was key in the selection of donors.
"We certainly don't believe it's discrimination."
Aids Foundation spokeswoman Dawn O'Connor said the foundation supported the service's view.
