The NRL Integrity Unit is investigating a sex tape involving NRL star Konrad Hurrell.
A video reportedly depicting Warriors player Hurrell driving while engaged in a sex act surfaced on the internet on Sunday night.
It appears the video was filmed on a phone and circulated on social messaging service Instagram before being deleted.
New Zealand actress Teuila Blakely confirmed she was the woman in the video.
"Yeah it was me, but it was a private video between me and Koni and it wasn't meant to have been leaked," the 39-year-old star of Shortland St told the New Zealand Herald.
Blakely said the film was taken two months ago and Hurrell sent it to a friend on Snapchat, an app which allows users to send photos and videos which are then automatically deleted after a short period of time.
She said she did not know who uploaded the video onto the internet.
The Warriors said they were investigating the matter.
NRL chief operating officer Jim Doyle said the league's integrity unit was looking into the incident and was waiting for the Warriors to report back.
"All I am going to say is that I am aware of it," Doyle said at the launch of the NRL Women In League round on Monday.
"Driving here to this function we were made aware that there is something there but we are following up on it now. We don't have any other knowledge."
