Becoming a father had also changed his mindset, particularly when preparing for a big game.
"I play for my family - I always have and now that I've got a wee family of my own, it's definitely put things in perspective. I definitely play for my little one now.''
Warriors captain Hoffman said he had always looked forward to being a dad one day and is now the proud father of Zach, 3, and 11-month-old Mia.
He said he enjoyed seeing his children's excitement and planning the big day with wife Mel.
"Father's Day takes on a whole new meaning when you're actually a father yourself. When you're a kid and before you have kids, it's all about someone else.
"So to have a day where it's dedicated to you - I just love seeing how excited my kids get, either getting presents or keeping a secret from me that they've done with their mum is something really exciting.''
Hoffman, whose father Jay Hoffman is a former Australian rugby league player, said family traditions he shared with his father were now things he now kept up with his own children.
"My dad played rugby league for the Canberra Raiders, so my memories of a kid is growing up going to training with dad and going to the footy - waiting for dad to come out of the changing room after games.
"To be able to share that same experience with my kids is certainly something really special."
Second rower Simon Mannering shares his parenting responsibilities with partner Anna. The couple have two children: Zeke, 2, and baby Jack, who was born in February.
Mannering, who celebrated his 30th birthday last week, said he was still getting used to celebrating Father's Day - being a fairly new dad.
"As a young fella, you always did something for your father on Father's Day. And now, to have some people you love dearly look at you in that same way on that day, it's pretty special.
He described fatherhood as being the best gift in the world.
"Some people don't get the chance to do that, so I'm very lucky to have my two sons. They mean everything in the world to me.''
