"But it has been just as good being around good people and making lifelong friends. It's a great game and it has been awesome to be a part of it.
"It's very rewarding and I'm grateful, but mentally and physically I'm nearly at the point where I don't want to just be hanging in there to earn a pay check.
"I want to be playing football and feel like I'm enjoying it and at the top of my game.
"So right now I feel it's a good time for myself to take that next step."
Humility aside, there's no doubting Halatau has made a significant impact on our game. Just ask Chris Lawrence - a player who has learnt plenty from the New Zealand-born hooker's professionalism over the years.

"Dene is a very quiet and humble guy that takes everything in his stride, but he comes in every day and just does whatever is asked of him," Lawrence said.
"Whether that's playing in different position or helping out younger guys, he just does it.
"His enthusiasm to turn up day-in and day-out is definitely something I picked up as a young guy coming through.
"He is what I think every young footy player should aspire to be like.
"I just hope he isn't lost to the game, because he is such a good mentor and role model."
"I've loved being in the NRL playing for the Tigers and at the Bulldogs as well and now I want to repay some of the good things that have happened to me."
Before hanging up the boots though, Halatau is fully focused on helping the Tigers make the finals.
It's a challenge starting with a must-win clash against St George Illawarra at ANZ Stadium on Sunday.
Halatau can't wait to take on the Dragons and his former premiership-winning Tigers teammate Benji Marshall in his 250th NRL game.
"I'm pretty excited for Benji," he said.
"Robbie (Farah), Chris Heighington and myself all debuted together in the same year, so it's great we are having milestones.
"I don't want to rain on his parade and I'm stocked for him, but hopefully we beat them. "But I'll definitely congratulate him on what he has achieved."
Halatau may be hanging up the boots, but he believes the Tigers will succeed in his absence.
"I think we are in a really good place," he enthused.
