Hegarty first signed to the main squad in January this year. He earned two caps for NSW in the first few matches of Super Rugby of 2016 before being struck by a season ending ACL injury in round two against the Brumbies.
The 24-year-old utility back has previous Super Rugby experience, having played 33 matches for the Melbourne Rebels, securing 49 points for the Club, including seven tries. He joined the Waratahs after a stint overseas in the Japanese Top League.
Recently back running, Hegarty will be ready in time for the 2017 pre-season.
