The league was founded in March 2010, by Trudy Hannon and Kyla Sinclair. By May of the same year the league was already attracting over 30 people to practices and by January 2011 the league boasted 50 members. The league began training in cramped conditions at Bell Hall until a new rink was opened at the Palmerston North Leisureplex in January 2011. In July 2011 the Swamp Rats played their first competitive bout against Mountain City Rollers and Mount Militia Derby Crew in New Plymouth. In August of the same year they hosted their first home bout - a round robin triple-header against Taranaki Roller Corp's Rumble Bees and the Richter City Roller Derby Convicts from Wellington. Swamp City won both their bouts, with the Rumble Bees taking out their bout against the Convicts. The league's A team was originally called The Plague. The team was later renamed the All Stars. The league has also had a B team at times. The first B team was called the Poison Ivies. After a year-long hiatus in 2014 a new B team was launched in 2015 called the Badda Bings. In 2016 the league renamed their Facebook page and website from Swamp City Roller Rats to Swamp City Roller Derby.
