NRL superstar Jarryd Hayne has been caught in an embarrassing pornography gaffe while presenting an online safety talk at a Gold Coast high school.

Hayne's online browsing history was being shown on a screen at the school, featuring mostly sports images, when a pornographic website was displayed on the screen to the 200-plus students at Robina State High School.

In a statement issued late Monday, Norton said it was continuing to investigate the incident but could "categorically confirm that the inappropriate images were not from Jarryd's mobile phone".

"The content was traced back to a Samsung device while Jarryd was utilising an iPhone," the statement read.
