Head coach Ian Millward has made eight new signings so far for his squad ahead of the 2013 Super League season.

Ins for 2013:

Justin Carney (Sydney Roosters)

Jordan Tansey (York City Knights)

Lee Gilmour (Huddersfield Giants)

Jamie Ellis (Hull FC)

Michael Shenton (St Helens)

Jake Webster (Hull KR)

Weller Hauraki (Leeds Rhinos)

Keith Mason (Huddersfield Giants)

Each of the new signings are described below.

England International centre Michael Shenton will rejoin his hometown club for the 2013 season.

He made his first team debut for the Tigers in 2004, going on to make 153 appearances for the club, scoring 93 tries. The former Smawthorne Panthers junior signed for St Helens following the 2010 season and scored a try for Saints in the Stobart Super League Grand Final last year.

On England duty, 'Shenny' has made 8 appearances for his country, scoring two tries.

After securing the signing of Shenton, head coach Ian Millward said:

“Michael is a quality centre who is very much a current International and has experience of playing in a Grand Final. It is brilliant news for the club both on and off the field. For him to make the decision to come back to Cas over quite a few other clubs is a big vote of confidence for us going forward.”

24-year old Carney has signed on a two-year deal from NRL side Sydney Roosters. He made his first team debut for Canberra Raiders in 2008 before signing for the Roosters at the end of the 2010 season.

Last season saw Carney play for the Roosters 17 times, scoring 3 tries. A former New South Wales Schoolboy, he was nominated in 2009 for the Ken Stephen Medal for his outstanding contribution in the community.

2010 was not such a good year for Carney as a badly broken leg kept him out for the full season. Carney can play in the centres or on the wing.

Upon signing Carney, head coach Ian Millward said:

“Justin will become a crowd pleaser with his robust running and dynamic style. No one will run the ball harder or faster in Super League in 2013.

"I'm hugely delighted with the capture of Justin. He'll perform a number of roles for us on the field as he is multi-skilled.

"He was pursued by many Super League clubs and thankfully I could call upon the friendship I formed with him at Canberra to get him across the line.

"He'll be a major part of us moving forward and it is clear he is excited about being a part of Castleford Tigers in 2013."

Jordan started his career with the Leeds Rhinos, making his first team debut against the Catalans in 2006, scoring a try in the game to make it a debut to remember.

The following year saw Jordan establish himself as a first team regular for the Rhinos, capping a brilliant season with the award of Yorkshire Evening Post Shooting Star of the year. The same season saw Jordan snatch a dramatic Millennium Magic win against the Bradford Bulls with a controversial last-minute try for the Rhinos.

In 2008, at the age of just 22, the Leeds-born Utility back agreed a two-year deal with NRL side Sydney Roosters. Jordan was only expected to stand as cover for first choice full back Anthony Minichiello, but after the Australian picked up an injury, he was given his chance. Jordan took his chance, making seven appearances for the Roosters before returning to his homeland to join Hull FC.

Jordan instantly became one of the Black and Whites key players. 2010 saw him make 25 appearances for Hull as they reached the end of season play offs. Just days before the 2011 season his contract with Hull was terminated for disciplinary reasons.

After spending a few weeks with Championship side Dewsbury Rams, Jordan returned to Super League with Welsh side Crusaders. He was a regular in their 2011 campaign making 18 appearances, scoring 5 tries in the process. Jordan left the Crusaders after they pulled out of Super League for the 2012 season.

Jordan has been playing this year for the York City Knights in the Championship, but in July agreed a one-year deal with the Tigers for the 2013 season.

After securing Jordan’s signature for next season, head coach Ian Millward said:

“We've signed him next year on his outstanding utility value. He has an impressive CV."

Gilmour made his first team debut with Wigan Warriors in 1997. The following year saw Gilmour become a regular, starring in the Warriors Grand Final triumph over the Leeds Rhinos. After spending five years with the Warriors, Gilmour secured a move to Bradford Bulls.

During his time at the Bulls the club enjoyed their most successful years. Gilmour was part of the side that lifted the 2003 Challenge Cup, as well as playing a major role in their journey to the Grand Final in the same year, although injury meant he missed the showpiece event.

At the end of the 2003 season Gilmour joined St Helens where current Tigers head coach Ian Millward was at the helm. The second rower spent six years with the Saints winning a long line of trophies (four Challenge Cups, Grand Final winner, World Club Challenge Winner). With the Saints Gilmour also was runner-up on many occasions.

Gilmour has spent the last two seasons with the Huddersfield Giants.

He has also played 15 games for Great Britain, his sole try for GB coming in the memorable 2006 Tri-nations victory over Australia down under.

On the signing of Gilmour, on a two-year deal, head coach Millward said:

"I recruited Lee when I was at St Helens; he comes with a unique C.V. of World Club, Super League and Challenge Cup success and International experience too. We were in need of someone with that experience and knowledge and that is why we have negotiated an early release of his contract at Huddersfield. He will not only be a valuable player, he'll also be a great mentor for our younger players. He's a very good communicator on and off the field and I'm delighted he'll be coming to Cas.

"People should dismiss his age as he's been very much injury-free throughout his career and has very good leg speed. He has the capabilities of emulating Steve Menzies well into his late 30s."

Jamie is a former Chorley Panthers junior who is a product of the St Helens academy. He made his first team debut for the Saints in 2009, at the age of just 20. First team appearances though were limited and Jamie signed for Championship side Leigh Centurions ahead of the 2011 season.

Jamie enjoyed a very successful season with Leigh, working under Ian Millward. He secured both the Championship player and young player of the year awards, scoring 34 tries in all competitions.

Hull coach Richard Agar moved quickly to sign the half back for the 2012 season. However, Peter Gentle was named the new Hull FC coach for the current season and Jamie fell out of favour. After only a handful of first team appearances for the Black and Whites, the Tigers announced the signing of Jamie for the 2013 season, but after securing an early release from his contract he joined the Tigers in July early. He made a memorable debut for the Tigers, scoring 24 points in their home victory over the Huddersfield Giants.

After signing Ellis, Millward said:

"Jamie is a player I think has an abundance of talent, he has a wonderful kicking game and is a player who has played regular Super League with Hull this year. He reminds me very much of an Australian style half back who likes to take the ball to the line."

Jake is a former NRL player who started his career at the Melbourne Storm and made a name for himself in the Storm's feeder side, the North Devils, before making 49 appearances for the first team.

After a season with the Gold Coast Titans in their inaugural year, he came over to these shores to sign for Hull KR in 2008. He has gone on to make 88 appearances for the Robins in Super League, scoring 32 times.

Jake is an International with New Zealand and was part of their 2005 Tri-Nations winning side. He has scored 5 tries in 8 appearances for the Kiwis.

After signing Webster, head coach Ian Millward said:

"I was looking for a specialist centre with experience and Jake ticks both boxes. He is a damaging runner and can create fear in opposition's attack with his defensive qualities.

"I believe the paring of him and Michael Shenton; two specialist International centres will be up there amongst the best in Super League next year.”

Second Rower Hauraki has signed for the Tigers from local rivals Leeds Rhinos on a two-year deal.

The 27-year-old was playing as a teenager alongside Tigers star Rangi Chase when he was snapped up by NRL side Parramatta Eels, making his first team debut for them in 2007. Hauraki went on to make 32 appearances over three seasons for the Eels.

In 2010, Hauraki joined Crusaders RL and was a major part of the side that reached the Super League play-offs for the first time, scoring 10 tries in 28 appearances for the Welsh club.

The following year Hauraki signed for the Rhinos, enjoying a successful 2011 season, picking up a Grand Final winners ring as well as appearing in the Challenge Cup final.

He has also represented New Zealand Maori on a number of occasions, including against England in 2010.

After completing the signing of Hauraki, head coach Ian Millward said:

"I was on the lookout for a second rower with a strong presence both on and off the field and I believe Weller offers the right qualities to fulfill this role. His experience and exceptional attacking qualities will provide us with great stability and composure on the field as well as a role model for the younger, less-experienced players on the team.

"He is a tough competitor and with his boxing background, I expect him to be a leading figure in training too. He ultimately gives us an overall package that is going to add a lot to the side next season. I look forward to working with him." 

As one of the toughest props in the game, Mason brings a wealth of experience to the club. Starting his career at Wakefield Wildcats, he went on to represent NRL side Melbourne Storm, before returning to the UK to team up with Ian Millward and Lee Gilmour at St Helens. The Dewsbury-born forward made his next move to the Tigers for his first stint at the club and left in 2006 to join the Huddersfield Giants.                      

Mason was named the 2009 Coaches Player of the Year and played over 100 games for the Giants. He made 19 appearances for the side in 2012 and joins the Tigers in full fitness.

Head coach Ian Millward said, "I was in search of an experienced forward who could offer a presence both in training and on the field and Keith fits that bill. Having previously coached him at St Helens, I know him to have one of the best work ethics in the game; he commands respect from his peers and will no doubt have a positive impact on the team.

"I am confident that Keith still has some of his best years ahead of him which should also create some healthy competition between the forwards."
