McAlister said the end of the Olympic campaign would mean the squad could now spend some time enjoying the atmosphere in Rio.
"At that level the sacrifice the players have made across the board, and the discipline they've shown has been outstanding... I don't think they'll be that disciplined tonight though for some reason."
The medal caps off a year of success for the McAlister clan, as earlier in the year Charlie coached Suburbs to Auckland club rugby supremacy, winning the Gallaher Shield.
"We all make sacrifices and our goal is always to try and make other people reach their potential, as a coach and a player."
Kayla's brother, former All Black Luke, didn't let being based in Toulouse in the south of France stop him from pestering his dad for constant updates.
"I was hearing from him 24/7 mate, he's painful, he was asking heaps of questions and I'm trying to watch the game," Charlie said.
"They talk all the time those two, he's extremely proud of her and her of him.
"We have ups and downs being the parents of two children who are borth elite talents, but we're proud of both kids across the board."
In addition to supportive parents, members of the team also received encouragement from their children, with Niall Williams' daughters Tatum-Lee and Rema-Rae showing their support for "Team Williams", with both mum and uncle Sonny Bill playing sevens for New Zealand in Rio.
