Leat lost his brother in February while the pair, along with fellow Kiwi Ryan Dill-Russell, competed for Commonwealth Games qualification in Sofia, Bulgaria. The 26-year-old said there had been some difficult moments in the months since but, conversely, the memory of Alister kept him striving towards his goal in Glasgow.
"I've had some really, really tough times, especially having to be overseas by myself, or just with a teammate or two, being away from home and friends and, especially, my parents.
"But when the going gets tough, all I have to do is think about him, and I've got that extra one per cent where I can push through. That's easy motivation for me."
As well as keeping him in his thoughts throughout the event, Leat competed with a more material memory of his brother - a tattoo that, when translated from latin, read, 'This is one of only two brothers'.
"This was definitely dedicated to him and I definitely had it in mind the whole day," he said. "I had a few emotional moments, especially during warm-up, when I thought about him, but you've got to try block that out and really focus on what you're doing up there.
"At my last competition, I thought about him a bit too much and I think that really ruined my performance on the day. It's just about controlling those emotions so you can perform to the best of your abilities."
A composed Leat managed to do just that during his gold-medal match against Englishman Danny Williams in the 73kg class. Although he fell behind to an early waza-ari, the Kiwi hung tough against his more accomplished opponent but never managed to battle back from the deficit.

Although the story-book ending failed to materialise, Leat knows he can move forward from these Games and continue to make his big brother proud.
"You're always going to be disappointed not to get that gold but, once I have a bit of down time, it'll really sink in. A silver medal's still a great achievement."
