新西兰Mainland Premier League

The Christchurch League started in 1998, a breakaway competition from the Southern League. The inaugural season had eight teams; Avon United, Canterbury University, Christchurch Rangers, Christchurch United, Halswell United, New Brighton, Nomads United and Western. The inaugural season was won by Christchurch United with a record 58 points, which was only beaten in 2020 by Cashmere Technical with 59 points.

In 2000, after the final season of the Southern League, the breakaway competition became the Federation 6 (Mainland) Premier League, the league was expanded to 11 teams, with two team outside of Christchurch; Marlborough United and Nelson Suburbs Reserves. The following season the league expanded to 12 teams, the additional team was Mid-Canterbury United.

In 2012, Woolston Technical and Cashmere Wanderers merged to become Cashmere Technical; they replaced the Woolston side that had finished sixth in the 2011 competition. Recently merged teams Coastal Spirit (Established between New Brighton AFC and Rangers AFC in 2008), and FC Twenty 11 (Established between Avon United and Burnside AFC in 2011) entered the Premier League through promotion from the Division One competition.

In March 2021, New Zealand Football announced a change to the structure of both the premiership and the top regional leagues around the country. The Mainland Premier League and the FootballSouth Premier League the Southern League. These leagues would allow local clubs to qualify for the premiership season (now known as the National League Championship), with the top 4 teams from the Northern League, the top 3 teams from the Central League, and the top 2 teams from the Southern League making up the competition, alongside the Wellington Phoenix Reserve side. All teams that qualify plus the Phoenix Reserves, would then play a single round-robin competition between September and December. For the Southern League, the two existing competitions run in the South Island (Mainland Premier League and FootballSouth Premier League) play their original league seasons for the teams to then qualify for a place in the newly formed competition. Five teams from Mainland Premiership, which covers the top of the South Island to Christchurch and three teams from FootballSouth Premier League, covering from below Christchurch to the bottom of the South Island, will qualify. The competition started on the 17 July 2021. During that time, the bottom three teams played in a qualifying league, with the top two finishers promoted to the 2022 Southern League.

In 2022, the league rebranded to become the Canterbury Premiership League (CPL), as there was no need to travel to Nelson.
