Rieko Iowane visit Argentina Prison

All Blacks stars Sonny Bill Williams, Rieko Ioane visit prison in Buenos Aires ahead of Argentina Test

On their day off, Sonny Bill Williams, Rieko Ioane, Ardie Savea and several other teammates shared their rugby knowledge with some of the inmates.

Williams said the experience was about giving back to the community.

"I think for us as people, it's our responsibility to help people less fortunate than ourselves," he said.

"I got tackled before and I hurt my knee, I might not be okay to play this weekend," Williams joked.

The All Blacks players went through a skills session and took photos with the inmates.
