Henry described his role as being part of a big team supporting a little team.
"There's going to be a huge number of English supporters. This is our opportunity to get behind the All Blacks.
"There's a chance to see history here. We want to become the first team to win three World Cups - Australia and South Africa have also won two - and we want this to be the first All Black team to win a World Cup away from home. That's very difficult to do.
"To be able to experience this phenomenal tournament from the supporters side is really going to be something different. I'm excited that Beaver and I can share this experience with a bunch of like-minded New Zealanders who share the same passion for rugby and the All Blacks as we do," Henry said.
All Blacks Tours general manager David Caldwell said the sales of packages to date has been "phenomenal".
"We didn't expect to be this far ahead after six months of sales given Kiwis are traditionally late purchasers," Caldwell said.
