Rawsthorne returns home after making switch from Hull KR to Halifax Panthers
Rawsthorne, 25, came through the Halifax reserve grade in 2016, scoring four tries in seven first team appearances and catching the attention of a host of clubs including Hull FC, where he moved for the 2017/18 Super League campaign.
Following loan spells at York City Knights, Doncaster and Leigh Centurions, Rawsthorne then earned a move to Toronto Wolfpack and became one of the most prolific scorers in the Championship, scoring 27 tries in 34 games, before moving to Hull KR.
The centre, wing or full-back is also a former England Academy rugby union star and becomes Simon Grix’s tenth new signing ahead of the 2021 campaign.
Rawsthorne said: "I am absolutely buzzing to be back at Halifax, it’s my hometown club and where it all started properly for me.
“We’ve got a really exciting squad for this season and I can’t wait to get stuck in.”
Head coach Simon Grix said: “I have said previously we are looking for new recruits and waiting patiently for the right ones. Shaun [Robinson] hanging up his boots moved us along a little quicker and we are really happy to welcome Nick back to his home town club.
“Nick left us as we couldn't provide the full-time environment he wished to test himself in. He comes back with a point to prove and an opportunity to kick start his career after a tough 18 months.
“He displayed his undoubted potential in his first stint and has learnt plenty in some good environments over the last few years. He returns with more experience and adds to the competition in our back line.”
Football Director Ian Croad said: "I remember meeting a young Nick in 2016 with his grandad, after Martin Gonzales convinced him back to the game. Truth is we always felt like 'the one that got away' when he left. I know Nick will do justice to the shirt, I’m really looking forward to seeing him play.”
