Folau signed a deal with the Waratahs at the end of last year but didn't feature in preseason due to injuries.
The younger brother of Israel Folau will start on the right wing in Friday evening's clash against the Kiwis, one of 15 Waratahs players in the 28-man squad.
South African giant Le Roux Roets is also set to make a start after his Super Rugby chances were dealt a blow with concussion in the final Waratahs trial.
Former Schoolboys Will Harris and Will Harrison are also in the squad, the latter starting at fullback.
The match will be a chance for backup hookers Andrew Tuala and JP Sauni to push their selection credentials after Tolu Latu's Super Rugby suspension.
Emerging Waratahs coach Shannon Fraser said the match would be a good chance for the next level of players to show their wares.
“Our team is combination of NSW Waratahs players looking for more game time as well as the emerging talent coming through our NSW rugby player pathway programs.
“We are using this as an opportunity to not only give our emerging talent more quality competitions, but also developing our support staff.
“Auckland Contenders are a quality side and we are expecting them to deliver a quality game of rugby."
