"I was surprised to be asked to play there but it's an opportunity and one I want to take."
It's not likely to precipitate a more permanent switch, with Issac Luke, Thomas Leuluai and Elijah Taylor certainties for the Kiwis when fit, but it adds to Henry's growing utility value.
It has seen him hit the books in preparation for Friday night's game.
"I'm going through the playbook," he said. "Normally I have to pay attention to only one page but at hooker I realise I have to look at everyone else, what plays to run and what certain people like.
"I was asking Siliva [Havili] for tips and tricks I can use on the field. It's good. It keeps me on my toes. The more prepared I am for this game, the better for me.
"I'm looking to facilitate the halves and forwards. If there's room to run, I will take it. [Coach] Stephen Kearney said if you feel the defence is being passive on you, then run - keep them guessing. I'm not looking to do anything flash in the first time in this position."
The NZRL will receive $700,000 from High Performance Sport New Zealand to help with their high performance programme over the next two years.
It's the first time the NZRL have received high performance funding and chief executive Phil Holden said it would assist the Kiwis with development programmes, management support, programmes to build intellectual property around the team and coaching academies.
