He plays for his Cullinane school team in the summer, and also made the local representative under 17 side.
Cullinane rugby coach Hayden Hepburn, who helped get Boult in condition for touch, said the New Zealand selectors judge players of three aspects - defence, attack, and physical strength.
"They're ranked and scored on their testing results.
"Out of those three [areas], Adam can control one of those three - the physical. He can develop the others.
"The kid sort of started working hard on the physical aspect of his rugby, which made it easy to transfer into touch."
Hepburn said the school incorporated touch among their official summer sports in 2012, and Boult had made the decision around 2014 to set aside his cricket.
To accommodate his talents even further, an interschool agreement was made for Boult to play in the Whanganui High School 1st XV this winter, and that team qualified for the final of 2016 Manawatu Colts competition, suffering the closest of defeats to perennial champions Massey White.
Boult was a standout at fullback.
In touch rugby, he prefers to be positioned in the middle of the pitch, acting as the "link" player.
He also hopes the New Zealand team can overcome the dominance of the Australians, who have won four of the last five Trans-Tasman series.
"They just said they're the best in the world. Fast, never stop," Boult said.
The teenager will be attending Massey University next year, undertaking a degree in sports management.
Despite his national touch honours, rugby union will remain his primary focus going forward.
