Choat's 2016 was a steep learning curve in time management. He was in the Auckland Rugby Union academy and juggling studies with club and union training.
"Last year was quite hard to balance everything. You get to the point where after weeks and weeks of training, it's quite hard to focus. You don't realise how easy it is at school. Uni is very independent but it's a big learning process. This year, taking that in to account, I talked to Royal Wolf and the university and dropped two papers this semester," he says.
He'll catch up and will have the laptop handy in Australia.
It is impossible to overstate the importance of the Jock Hobbs Memorial Under 19 tournament as a springboard for some careers. Choat made a real impact for Auckland A in 2016, who made the Premiership final. Often off the bench, he revealed a nose for the ball and the tryline.
"It was good because, coming from a 1B school, I didn't get noticed as much. Getting into the ARU academy, playing prems... that tournament meant I knew I could compete with quality guys from the other provinces. It was a really good experience, a first crack at semi-professional rugby for my province," he says.
Then things started to fall into place after that national, televised, exposure.
"Originally I wasn't supposed to trial, but due to an injury I was brought into the December camp and went reasonably well. I was selected for the March camp and, from the feedback I got, I really pushed my way in. It was good to come from that and get in," he adds.
His rugby diet since has consisted of three games for the Blues Under 20s and a club outing on April 8 for Waitemata. If all goes well, he may not be back in his club colours until late June or early July.
Expectations for this Oceania series ahead of the World Rugby Under 20 championship in Georgia, which starts late next month?
"There's three opensides (Canterbury's Tom Christie and Auckland Under 19 teammate Dalton Papali'i are the other two), so I'm thinking we're going to be starting a game each. I'm hoping to play as much as I can and prove that the coaches were right to pick me," declares Choat.
New Zealand head coach Craig Philpott says Choat has played his way into the squad.
"Adrian is someone who took his opportunity in the March camp, when we had a trial. He got more game time than we initially thought he might, through injuries, and demanded selection. He's got an opportunity at that next level to show that he's ready to go to a World Cup," says Philpott.
