Henry will step down after the match at Eden Park but Hansen, who previously replaced his superior as Wales coach, has insisted that he is only concentrating on the match against France.
"Four years ago we got knocked out in the quarter-final of a World Cup, and three coaches (Henry, Hansen and Wayne Smith) made a decision to try and re-get the job, and we did that," he said.
"We were lucky enough to get reappointed, and last weekend we earned the right to turn up on Sunday at nine o'clock to try and win the thing.
"That is the only thing I am thinking about. I don't really care what happens after Sunday. All I am focusing on is trying to get a team ready to turn up to win."
Sunday's match is a repeat of the tournament's inaugural final of 1987.
