The 30-year-old former Tonga international, who has scored 55 tries since joining the Black and Whites from South Sydney in 2014, also has the option to extend his stay by another year.
Talanoa said: "Signing a new deal is something that I've been thinking about for a while now.
"I knew I needed to put in some good performances at the start of this year to earn a new deal, and I'm glad I did that."

Talanoa was one of head coach Lee Radford's first signings, and he is delighted to have retained his services.
"I'm over the moon to have Fetuli tied down for next year," Radford said. "He's a big part of the culture we have here, and he's been a real revelation since joining in 2014.
"He was a left-field signing but has proved to be a fantastic addition over the last few years."
