The 29-year old is is just two months into a four-year deal with the Rhinos, who have won just won of their opening eight matches.
And while Merrin has admitted to finding things tough throughout Leeds’ struggles, he remains committed to the cause.
“It was always going to be a challenge to come to a different country and get used to new things,” he told Sky Sports.
“But that’s what I came here for, to step out of my comfort zone, to try something new and come into a new group.
“People will see how we’re going at the moment and take that as me not enjoying what’s going on. Obviously you’re not going to enjoy losing, you’ve got a problem if you do enjoy losing.
“There’s a lot of outside noise at the moment and it’s hard to push that away when it’s in your face all the time with social media, but I’ll focus on what I can control and my part in turning things around.
“It’s a tough time and that’s what rugby league is. You wouldn’t do it if you weren’t made for it.
“Obviously the season hasn’t worked in our favour and at times it does get hard, but you’ve got to go through tough times to realise what sort of a person you are and I’m not turning my back on this team.”
Merrin was encouraged by what he saw last week as something to build off moving forward.
“I think we showed some good signs at the weekend, even though we didn’t get the win,” he said. “It was probably our best performance collectively.
“We’ve shown some great performances and let our foot off the throat and it’s cost us dearly in the end.
“We’re still building but the drive and the will and the passion that we have among this group is incredible.
“At the weekend, I think we set a good standard to build on.”
