The death of the 33-year-old utility back, who also played for Tasman and three different Super Rugby teams, was confirmed by the Tasman Rugby Union yesterday.
"It is with great sadness to hear of the passing of Billy Guyton [a 52-game Mako player, and recent coach of our FPC Mako team]," the union said on social media.
"Billy was a much-loved member of our whole Tasman Rugby Union team and had a positive impact on those he played alongside and coached. Billy has been a major contributor to the development of women's rugby across our Tasman region."
Guyton, who was raised in Waimate and later represented the Valley and Excelsior clubs, played 29 games for North Otago in the Heartland Championship from 2010 to 2012, scoring 89 points.
He started all 11 games at fullback in 2010, when the Old Golds won the Meads Cup, and earned selection in the Heartland XV.
He also played every game (10) at fullback in 2011 before showing his versatility in 2012, splitting his eight starts between the No15 jersey and midfield.
Guyton then morphed into an exceptional halfback after signing for Tasman.
He played 24 games for the Blues and one each for the Hurricanes and Crusaders, and toured with the Māori All Blacks in 2016.
His death was "absolutely devastating news" for everyone who knew Guyton, North Otago union chief executive Colin Jackson said last night.
"He was widely admired for his rugby skills and deep passion for the game.
"Billy was a true club man who proudly wore his team’s jersey and he thoroughly enjoyed the camaraderie that goes with a rugby team.
"Humble, thoughtful and truly gifted, Billy Guyton will always be remembered as one of North Otago’s finest players.
"Our sincere condolences go out to Billy’s family and friends."
