Sitiveni Sivivatu has strongly denied being involved in an alleged sexual assault in an Auckland bar in the early hours of Sunday morning.

Newstalk ZB earlier reported that a woman had accused the 25-year old winger of indecently assaulting her at an Auckland bar.

But later this afternoon, the station said the woman was unsure about the identity of the man who allegedly assaulted her.

In a media statement issued through the Chiefs, Sivivatu said he was at his Hamilton home with his wife when the alleged assault was said to have taken place.
