Born in South Africa, Prumm emigranted with her family to New Zealand in 1995, when she was seven years old. The Prumms settled in
Bombay, south of the
Auckland Region. Thanks to her achievements, she joined the official
Kawasaki team. In 2005, at the age of 17, Prumm competed in the first Women's Motocross World Cup, the forerunner of the current World Championship (WMX) and finished second behind the German
Stephanie Laier. In 2006 and 2007, she won the World Cup. and she had finished in the ninth position. Prumm's racing career was cut short shortly before the start of the 2009 season. In a training session in New Zealand she landed badly after a jump and broke her back in three places (specifically the vertebrae T6, T9 and T12). Although it appeared that she would never be able to walk again, she eventually fully recovered from her injuries, but her time as a motocross racer came to an end. ==Life after racing==
