Making five appearances in that tournament, he took a total of 10 wickets at an average of 14.30, with best figures of 5/51. His performances for Denmark caught the attention of Hampshire, with Hansen joining the English county for the 1997 season.

He went wicketless in the match, while with the bat he recorded scores of 12 not outand 19. Having spent most of the 1997 season in the Hampshire Second XI, this again was the case for the 1998 season, with Hansen not featuring in any of Hampshire's first-class matches that season. He featured heavily for the Second XI in the 1999 season, but did make three first-class appearances in the 1999 County Championship against Sussex, Northamptonshire and Somerset. He took a total of 5 wickets in these three matches, which came at an average of 39.20, with best figures of 3/59.

It was in 2000 that he made his debut in List A cricket for Denmark against Zimbabwe A in the 2000 ICC Emerging Nations Tournament. Hansen made five appearances in that tournament, which was hosted in Zimbabwe. He took 9 wickets at an average of 14.11, with best figures of 3/20.

His next major appearance for Denmark came in English domestic cricket in the 2003 Cheltenham & Gloucester Trophy against the Leicestershire Cricket Board, though the match which was a first round fixture was played in August 2002 to avoid fixture congestion the following season. Denmark lost the match by 4 wickets. The following season, he appeared for Denmark in the first round of the 2004 Cheltenham & Gloucester Trophy against Wales Minor Counties, with the match itself played late in the 2003 season in a similar arrangement to that already mentioned. Denmark again lost the match. Hansen played in his third and final ICC Trophy during the 2005 ICC Trophy in Ireland. In a change from previous tournaments, this ICC Trophy held List A status. He made six appearances during the tournament, with him taking 15 wickets at an average of 14.00, with best figures of 6/30. These figures, which came against Uganda, were his maiden List A five wicket haul. Hansen also scored 75 runs in the tournament, including recording what remains his only half century, scoring 51 against Bermuda. In total, he represented Denmark in 19 ICC Trophy matches, taking 36 wickets at an average of 14.02.
