Aso quickly impressed in the Hurricanes match day squad and established himself as a rising star. In the 2017 season, he was the team's second highest try scorer – crossing the stripe 14 times – and was on track to hit the same mark in 2018 before a wrist injury ended his campaign prematurely.
His early season form, however, had caught the eye of All Blacks selectors, who suggested he would have been in the frame for a call up to the national squad for the Rugby Championship had he been fit.
"That was a big shock to me, hearing about my name being thrown around the All Blacks coaches," Aso admits. "I knew I wasn't going to be able to play so I was gutted but I was also happy as well. It was something that made me want to work even harder, hearing about it."
However, it was five months before Aso he was able to pass a ball again and get back into training, so there was no chance of a miraculous recovery and a shot at securing All Blacks jersey.
His form in recent years hadn't just brought him to the attention of the national selectors, but a number of clubs abroad were interested in bringing the rising star over to their clubs.
Aso received multiple offers from France and Japan for 2020 and beyond, but knocked them back to re-sign with the Hurricanes and New Zealand Rugby.
"I was flattered, but told them I wanted to accomplish some goals and not leave New Zealand without any regrets."
Committing to the Hurricanes and New Zealand Rugby until the end of 2020, Aso has no doubt he'll be able to get back into the form that he's shown over the past three years – putting in plenty of extra work heading into the season to take his game to another level.
"The work behind the scenes that people don't see is what made me perform to my best at times. (It's about) doing little extras where I can sharpen my skills and not getting bored of doing the same, basic skills that can be crucial at times during a game."
