Henry made his first-grade debut against Manly in 2012 and last year played his first test for the Kiwis.
"We've already had five players appearing for the club for the first time and now Nathan and Ben reaching these milestones," said Warriors coach Andrew McFadden. "They're occasions we place a lot of emphasis on.
"It's also special to have two such valuable team members being able to bring up their milestones in front of family, friends, members and fans at our home. Friendy and Ben have made terrific contributions to the club and I know the rest of the boys are thrilled for them.
"We're also excited to be at home for our next two games in our 20th anniversary season. We can't wait to get out there in front of our own supporters after two tough games on the road. This is the place the boys love playing at with a big and vocal crowd there behind them."
