Wakefield pair Jacob Miller and David Fifita have extended their contracts with the club for an additional two years.
Miller joined Trinity from Hull in 2015, while Fifita moved to the club last season from Cronulla Sharks.
Head Coach Chris Chester said: “I’m delighted that we’ve managed to agree a new deal with Miller – it’s important for us to keep our best players at the club and by doing so it shows we are heading in the right direction.
“Jacob is still a young player with exceptional talent. I’m looking forward to working with him for another two years and see him improve even more.
“Fifita has become an important member of the squad since joining us back in June last year and I’m thrilled that we have been able to secure him for another two years and to continue to build our squad for the coming seasons.
“He has so much passion for the club both on and off the field which is great to see.”
