"We're pretty focused on winning the World Cup and we think [Williams] is an undeniable talent - not only what he brings on the field but also off the field, I think it important, in terms of the culture and the team environment.
"We went through quite a robust discussion and had a lot of discussions over the course of the evening. We had to check first that we could actually take him and, once we knew that we could and we knew the timing was there that allowed us to do that, we then had to front up to the difficult decisions around the conversations with Tohu.''
Harris was offered something of a consolation prize _ the chance to travel with the squad to the UK in a development role and play pre-tournament against the Cook Islands _ but Harris and his club, after consultation with Kearney opted against accepting.
Holden hoped Harris would not become alienated from the national set-up in wake of his exclusion and said the coaches and selectors were ready to cop the brunt of any criticism.
"That's been the key for me and I made that very clear with the coaches - if we wanted Sonny in the team then we had to be prepared to front up.
"I think we're going to put our arms around Tohu, and I know the team are going to make sure there's lots of messages of support. Once the emotion's gone out of it for him, I'll give him a call myself, but we'll do everything in our powers, around the key words of integrity and respect, to make sure it's managed appropriately.''
