Sonny Bill Williams made some children's dreams come true by spending time with them at the Bayleys National Sevens at the weekend.
"I've learnt a lot about preparing well for sport and had opportunities to be involved across a number of sporting codes.
"It's important that our next generation of players have the opportunity to learn how to perform well. That's why I've teamed up with ACC, to pass on some of my knowledge and help kids enjoy sport safely."
Williams said investing time into your body to prepare for the demands of whatever sport you want to do well in was key for success in a sporting career.
"Don't take shortcuts. If you want to perform at your best and avoid injuries, you need to be prepared and train smart."
