The move will bring to an end a five-year association with the Ospreys for Tiatia, who moved to the region from Toyota in the summer of 2006, a period that has seen him establish himself as an Ospreys legend on the field as well as embarking on his fledgling coaching career.
After cutting his coaching teeth with as Defence Coach with Swansea he became an age-grade coach within the Ospreys Elite Youth Development programme, before taking up a coaching role working with the B group at the Ospreys as well as specialising in the tackle contest area. During this time, Filo and his family have settled in the region, with three of his five children born in Swansea.
Speaking about his decision to take up the post at Toyota, Tiatia said: "I'm very sad to be uprooting my family and moving on from Swansea and the Ospreys, but it's a decision I'm making firstly to be nearer home and my family in light of some of the events that have occurred in the southern hemisphere recently and secondly, on a professional basis, as it allows me to make the next step in my coaching development.
"I've had five years here and I'll take away some great memories from my time as an Osprey, not least three children who were born in Swansea, so I will always have a very strong connection.
It's been a fantastic time and the supporters have really taken to me as one of their own, which is the best thing I can say about the region. I know that I will always remember my time here, and I sincerely hope that I have been able to leave some kind of legacy that Ospreys fans will remember me for."
Elite Performance Director, Andrew Hore, paid tribute to Filo for his outstanding service over the last five years, wishing him the best of luck in his new role: "Filo has been a tremendous servant to the region in his time here and obviously we will be disappointed to see him leave at the end of the season, but as both a family man and a dedicated professional, we can fully understand and accept the reasoning behind his decision.
"He has been an asset to the organisation on and off the field. As a young coach he has learnt the ropes on the Ospreys Coach Development Pathway over the last four years, having a huge influence on the next generation of Ospreys, and will definitely leave his mark on the organisation," he said.
