Hardaker joined Penrith mid-season on a loan move from Leeds.
The Englishman has featured in the centres and at fullback, as well as coming off the bench.
He is scored his first try last weekend against Brisbane.
“It was always going to take time and I feel like I’m getting there now. To get another game under my belt and get a try is pretty special for myself,” Hardaker told NRL.com.
The England international sat for 80 minutes on the bench in Round 19, not receiving any game-time.
“That was a tough one; every player would probably tell you he wants to go out there and play,” Hardaker said.
“I do get a bit upset, I probably was for the first 10 minutes after the game but ‘Hook’ (Griffin) came straight up to me to be fair and apologised and said he didn’t want to change the team as it was quite close and could have gone either way and I totally understood that.
“I’m here for the team, I’m not here to be an individual.
“I was happy for that afterwards and came into training smiling a couple of days after and trained as hard as I could and he put me on the bench again [for the Brisbane game last week].”
