Wakefield coach Richard Agar says squad continuity is key to the club’s future progress.
Agar’s side are still in the hunt for a second successive play-off place, in his second year in charge.
He told the club’s official website: “It’s paramount and very much a priority that all the good work we’ve done over the last 18 months, we don’t lose in the short term. Tying down our best and most influential players – and some of our young players too – is very important.
“We’ve got a very strong spirit and sense of togetherness within our group and that runs right through the staff and down the whole squad. We’ve got players we’re getting a lot out of and players who are very happy to be representing this club.
“In the days where players can move quite easily and in a market that’s very player driven, it’s great for us that we can hold onto our best talent because they believe in each other and believe they can achieve what they want out of the game at the club.”
Upon his arrival from Hull, Agar brought in 17 new players ahead of the 2012 season.
