Moriarty, 24, has this week joined up with his new team-mates following the Wales summer tour to Argentina.
His move to Rodney Parade has certainly attraction plenty of media attention, but the back rower is keen to let his rugby do the talking when he pulls on a Dragons jersey for the first time.
“I don’t feel there is a lot of expectation on me, it’s a team sport and I’m just a piece of the jigsaw. I will contribute what I can, when I can,” he said.
“After meeting with Bernard (Jackman) I knew this was the place to come. I liked what he had to say and I liked him as a person, which is always good when you sign for a new club.
“There have been a lot of changes since last season, players leaving and players coming in, and I’m excited to see what we can do.
“Everyone knows what I’m about and that is what I going to bring every week. People shouldn’t expect anything less.
“I’m really excited about a new start here,” he added. “Already I’ve seen the boys working hard for each other and I’m excited about what we can do.
“It’s nicer to be a little bit closer to home and in an environment where I know a lot of boys from when I was younger.
“There are quite a few boys here I used to play against or played alongside when I was a bit younger. Obviously Richard (Hibbard) has come along with me too. I’m looking forward to getting back on the field.”
Moriarty will miss the opening game of the Guinness PRO14 season as he serves a suspension for his red card against Argentina in Sante Fe in June.
However, Moriarty – who has apologised and accepted his ban – insists he will not change the physicality and aggressions he brings with his game.
“I was disappointed to finish the tour the way I did, but there is plenty of rugby to look forward to and I’m sure when I get back to it I will definitely make up for it,” he said.
“I do what I do, I’m not going to change that. I will make it up to the boys when I come back.
“Considering how little I played last season, I was happy with what I got through during that tour,” he added.
“I felt I made good impacts on the games, I felt my physicality was right and that was what we needed with a young squad and players who had not played for Wales.”
