The Prince, who will watch Saturday's Wellington Test as part of his 11-day official visit to New Zealand, was shown some of the practices and routines that players go through as part of their training.
He also got to have hands-on experience of kicking, something Alred believes the Prince will now appreciate more.
Alred said: "It is a great opportunity for William to experience some of the techniques and processes that the main kickers go through for their practice and preparation for games.
"I am sure that he has got a better understanding of the work put in by the likes of Charlie (Hodgson) and the other kickers."
Hodgson added: "I enjoyed the session, I was bit nervous at first with all the media there, you know that you get similar numbers at a game but you don't notice them because of the crowd.
"But we soon settled into the normal routine, like any other session. William was a very down to earth bloke, whose skill and accuracy improved as the session progressed."
