In 1994, he surprisingly got a place in Egil Olsen's squad for the 1994 World Cup in USA playing in one game, but Rushfeldt never established himself as a regular having only won a total of 7 caps by 2001, and he did not score his first goal until 2002 in a game against Japan. In 2006, he announced his decision to retire from the national team. However, in 2007 he reconsidered his decision and agreed with the national team coach Åge Hareide that he would make himself available for the game against Bosnia because John Carew was unavailable due to injury. He came on as a substitute in the game against Bosnia, making his first national team appearance in 2 years. Norway failed to qualify for the European Championship and he retired for good from the national team. He ended his international career playing 38 games scoring 7 goals.
