Naiqama was a key recruit leading into the 2015 season, originally inking a one-year deal following his departure from the Penrith Panthers.
The 26-year-old has since played on the wing in all six matches this year, with the new contract securing the talented winger through until the end of the 2017 season.
Naiqama has scored 18 tries in 29 NRL games since making his debut in Round 26 of the 2010 season for the Newcastle Knights.
“I’m really excited to secure a deal with Wests Tigers long-term,” Naiqama said.
“I was only here on a one-year deal previously because I came to the Club looking for an opportunity.”
