Kurt John Sorensen is a New Zealand former professional rugby league footballer who played in the 1970s, 1980s and 1990s. He is the brother of fellow Kiwi international, Dane Sorensen, and the nephew of another pair of Kiwi brothers, Bill and Dave Sorensen. He is of Tongan and Danish descent. Kurt's rugby league journey, though beginning slightly later then his brother, was no less impressive. His Kiwis’ debut in 1975 kicked off a remarkable 14-year tenure with the national team - a record that stands unmatched to this day.

While playing in the Auckland Rugby League competition, Sorensen made his debut for the New Zealand national rugby league team in the 1975 World Cup. The following year, while playing for Mt Wellington, he won the Auckland Rugby League's Rothville Trophy, which is awarded to the Premier One player of the year as chosen by the Auckland Coach. Sorensen then moved to England to play for Wigan for the 1976/77 season. He later played for the Cronulla-Sutherland Sharks, finishing the 1982 season as the club's top try scorer.

In 1983 the committee addressed the Sharks players at pre season and admitted the club were in financial trouble and going broke. They only way they could see out of it was if the players took a 50% pay cut for the season. After that, many of the players, including Kurt and Dane became free agents. The brothers manager suggested they shop around and find the best deal before returning to the Sharks in 1985 when legendary coach Jack Gibson was set to take over.

In 1984 they moved on to the Roosters and met an offical under the stands to negotiate a deal for both Kurt and Dane Sorensen. To help make a decision, two famous brown paper bags were placed on the table. Kurt and Dane looked in the bags, then looked at each other, and said - where do we sign. Unfortunately, New coach Laurie Fryer bought a range of Grid Iron techniques after a trip to the USA, which most players couldn't grasp. With a number of defeats the coach would regularly change out 6-7 players per week, leading to only a handful of first grade games for them.

While at Widnes, Sorensen played in 252 games and captained the side that won the Championship in 1987/88 and 1988/89, the Premiership in 1987-88, 1988/89 and 1989/1990 and the 1989 World Club Challenge. He also played in the Widnes side that were losing finalists in the 1992-93 Challenge Cup bursting through the defensive line from 20 yards out to score the opening try at Wembley. In 1986, after returning from the English season, Sorensen made some cameo appearances for the Northcote Tigers in the Auckland Rugby League competition. During the 1989/90 season, Sorensen captained defending champions Widnes at second-row forward in their 1989 World Club Challenge victory against the visiting Canberra Raiders. Kurt Sorensen played left-prop in Widnes' 24–18 victory over Salford in the 1990 Lancashire Cup Final during the 1990/91 season at Central Park, Wigan.

Kurt Sorensen played left-prop in Widnes' 6–12 defeat by Wigan in the 1988/89 John Player Special Trophy Final and played left-prop, and scored a try in the 24–0 victory over Leeds in the 1991/92 Regal Trophy Final during the season at Central Park, Wigan. After leaving Widnes, Sorensen was the player-coach at Whitehaven before controversially joining rivals Workington Town in 1995. He resigned a year later before resuming his playing career with Chorley in England, and Cudgen on the Gold Coast

Panthers forward Scott Sorensen became the fifth member of his family to play for the Kiwis when he made his Test debuts in the World Cup. The 29-year-old's selection comes more than 70 years after his late grandfather Bill Sorensen began his New Zealand career.

Bill went on to play 24 Tests from 1951-1960, while his brother Dave, who is Scott’s great uncle, represented New Zealand in 1971-1972. Scott's uncles Dane and Kurt Sorensen left an indelible mark on the rugby league landscape, playing 45 Tests between them for the Kiwis in the course of their outstanding professional careers spanning the 1970, ‘80s and ‘90s

Kurt made almost 130 NRL appearances for the Sharks and more than 250 for Widnes, ending his career with the club with a try in the 1993 Challenge Cup grand final loss to Wigan. Kurt and Dane Sorensen played more than 600 games of professional rugby league between them and in 2024, the brothers were “immortalised” at the Auckland Rugby League Annual Awards.

For Kurt and Dane, their impact on the sport extended well beyond their playing days. In 2000, Kurt's contributions were acknowledged with his induction into the elite circle of NZRL Legends of League. Now, with their elevation to 'ARL Immortal' status, both Dane and Kurt Sorensen's legacies in New Zealand rugby league are forever enshrined, honouring careers that helped shape the sport in Aotearoa.
