The Warriors have re-signed Ligi Sao until the end of 2019 and secured Canberra fullback-wing Zac Santo for the rest of this season and next on a second-tier contract.
Sao returned to the Warriors last season after a three-year stint with Manly but an injury affected season saw him make only two appearances off the interchange bench against Canterbury and Melbourne.
The 24-year-old has already made seven showings off the bench this season but last featured in the round 10 defeat to Penrith.
Santo made his NRL debut with North Queensland in 2014 and has been used twice at first-grade level since joining the Raiders in 2016.
A regular for Canberra's feeder club the Mounties in the Intrust Super Premiership, he was named at fullback in the ISP team of the year last season.
