The trial by University College London compared rates of HIV in 545 gay men at very high risk of the infection. Of those given Truvada as pre-exposure prophylaxis or "PrEP", 1.1 per cent developed HIV, compared with 7.1 per cent of those not given the treatment.
A British HIV/Aids charity, quoted in the Telegraph, said, "PrEP is, quite simply, a game-changer".
NZ Aids Foundation executive director Shaun Robinson wants it trialled in New Zealand in high-risk gay men and has had preliminary talks with the Ministry of Health.
But the ministry first wants to see peer-reviewed and published results of the British trial.
