A Campbelltown Collegians junior, Nofoaluma has played 19 NRL games since making his debut in Round 10 of the 2013 season against South Sydney.
During his time in the top grade, the 20-year-old has crossed for 11 tries including the 2013 Dally M Try of the Year against Manly-Warringah at Campbelltown Sports Stadium.
Nofoaluma was part of the premiership-winning Wests Tigers Holden Cup side in 2012 and last year represented the Junior Kangaroos.
"The Club has been great to me over the years and I'm really enjoying my football," Nofoaluma said. "Being a local junior, I've made some great friends coming through the grades at Wests Tigers and playing alongside those guys is something I cherish.
"I've always supported the Wests Tigers; it's a great feeling to be now playing NRL for the Club and I'm thankful for the opportunity I have been given," he said.
Head Coach Mick Potter was pleased with new deal for Nofoaluma, which will see him remain at the Club until the end of the 2017 season.
"David is yet another local product that the Club has secured on a long-team deal," Potter said. "He is a pleasant young man who is great to work with and is always great to coach.
"We have already seen how talented David is and he keeps on getting better. He no doubt has a long, bright future ahead of him," he said.
Wests Tigers CEO Grant Mayer said the Club is now focused on securing the remaining off-contract local juniors.
"This is a significant step forward for the Club in completing the retention of our local juniors," Mayer said. "David has been dynamic since his debut against the Rabbitohs last year and has quickly become a crowd favourite.
"To retain him with so much interest from other clubs is a real coup and a testament to the culture that we are building at Wests Tigers."
There are a number of other players that the Club are working on securing and remain hopeful that further announcements can be made in the coming weeks.
"Negotiations are never as straight forward as they seem but I have been consistent in my messaging that the retention of our local juniors is a priority," Mayer said.
"After discussions with player managers, the players themselves and our coaching staff, I'm convinced that we are on the same page.
"For avoidance of doubt, I'll be making no comment about specific players until we have a good news story," he said. "In the meantime I implore our fans to come out to Campbelltown Sports Stadium on Saturday night and cheer on the Wests Tigers - #2560."
