The game was due to be played at the John Smith's Stadium on Monday, May 29, but will be rescheduled for Friday, June 16, which was a blank weekend for both clubs following their exit from the Ladbrokes Challenge Cup.
The switch means the two clubs will no longer have to play two games in four days but Giants managing director Richard Thewlis says the move was prompted by the success of their cotenants.
"Since Huddersfield Town's magnificent victory we have been inundated with calls from supporters wanting to share the Wembley experience as well as a huge number of stadium staff here which made the actual staging of our game extremely problematical," Thewlis said.
"It's fully expected that 40,000 Huddersfield sports fans will descend on London that day to hopefully see a Town win and with both ourselves and the Saints having a free weekend later in the year the move made a lot of sense to us both."
