"I'm doing a bit of coaching at the moment with the academy within the Ospreys," the 37-year-old told BBC Wales' Scrum V.
"And if the opportunity does arise then I'll take it with two hands."
Tiatia, who won two caps for New Zealand, moved to Wales after a four-year spell in Japan with Toyota Verblitz.
He was an EDF Energy Cup winner with the Ospreys last season but, when he does decide to retire from the game, he hopes that the Ospreys will be in a position to enjoy long-lasting success.
If an opportunity to continue to help the Ospreys move in that direction arises through a coaching capacity, then Tiatia intends to put any thoughts of moving home to New Zealand firmly on the back foot.
"I'm really enjoying it, I lived in Japan for four years and just experiencing different cultures and different living experiences.
"And I think coming to Wales, it's broadened my horizon a little bit more and…when I do hang up my boots - and it'll be pretty soon I'm imagining - I'll be telling everybody it's part of my history.
"I've lived in a great country, surrounded by great people, but also trying to create a legacy here as well within this organisation, the Ospreys."
