"I felt there was an opportunity to have a discussion with (New Zealand chief executive) Steve Tew whether or not we can play the All Blacks," Ritchie said.
"I'd have been failing in my responsibility if I hadn't explored the possibility of an All Blacks game bearing in mind we haven't played them since 2014 and bearing in a mind it's the game that everyone wanted to see.
"I had discussions at the behest of Eddie, not because of any economics. The only reason for having this match was because Eddie wanted to have it. This was not driven by economics.
"Was it possible to organise and was it the right thing to achieve that for the fans, because Eddie wanted it and the opportunity was there.
"It came up in conversation – I asked Eddie if he wanted to play this game if there was a possibility of doing it, even if it was difficult to arrange because of the economic discussions needed. Eddie said yes, absolutely.
