In 1999, Zuiderent was signed by Sussex, and played for them up until the end of the 2003 season. During this period, he did not always appear regularly for the Netherlands team as he believed that playing in matches for Sussex would be more beneficial to his career. Most notably, he missed the 2001 ICC Trophy competition in which the Netherlands earned qualification for the 2003 Cricket World Cup, but he did later represent his country in all their matches at the 2003 World Cup.
After leaving Sussex, Zuiderent returned to the Netherlands and once again was a regular member of the national team. In the 2005 ICC Trophy, he scored three centuries and finished as the tournament's top run-scorer. He produced a man of the match performance in the 5th/6th place play-off against the United Arab Emirates, carrying his bat and scoring 116 not out. The win ensured that the Netherlands would qualify for the 2007 Cricket World Cup and receive ICC funding and ODI status for four years. Zuiderent was named as the Player of the Tournament.
