The Mainland Premier League is a league competition run by Mainland Football for association football clubs located in the northern half of the South Island, New Zealand. It is currently regarded by the New Zealand footballing community as the strongest football league in the South Island of New Zealand and features current and former ASB Premiership players.
The competition currently runs between March and August each year, and consists of seven teams based in Christchurch, and one team in Nelson. There are 21 rounds where teams play each other three times. The winner of the league qualifies for the South Island Championship, a one-off game against the winner of the FootballSouth Premier League, which is hosted by the two federations in alternate years.
By statute, the winners of the Canterbury Championship League, and Nelson Bays region's Division One League play in a home and away play-off, with the winner of the tie receiving promotion to the Premier League. However, due to potential extra costs including travel, the winner of the Nelson Bay's Division One title forgoes the right to a play-off. This effectively means that the winner of the Canterbury Championship League title is promoted to the Premier League.
In 2012, Woolston Technical and Cashmere Wanderers were merged into Cashmere Technical, they replaced the Woolston side that had finished 6th 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 the 2012 season, Christchurch United were relegated from the league after a season-long relegation battle with FC Twenty 11. Nomads United, who won the Division One title, have been promoted back up to the Premier League. Coastal Spirit completed a switch of home ground for the 2013 season from Linfield Park to Cuthberts Green. However, in 2014 they were forced to move back to Linfield because Cuthberts was deemed not up to be up to Premier League standard by Mainland Football. Universities were also forced to play their home games away from Ilam fields for the same reason.
The 2013 season was one of the closest competitions in recent memory. Ferrymead Bays set the pace early on, but soon fell away in the middle of the season after 4-0 home defeat to Nelson Suburbs in a top of the table clash. Eventually after several strong title challenges by the top four teams Cashmere Technical emerged victorious, succumbing to only two losses in the league, and 3 in a season that saw them win the treble which also included the South Island Championship, and the Chatham Cup. FC Twenty 11 were relegated to the Mainland Division One Competition, with the University of Canterbury replacing them after securing the Mainland Division One title.
The 2014 season began with Nelson Suburbs being beaten 4-1 at home by the newly promoted Universities. Both Cashmere Technical and Western continued their strong form from the 2013 season. Cashmere were unbeaten for the first 10 games until an 11th round 1-0 defeat to Nelson Suburbs on 31 May. This was Cashmere's first defeat since 1 June 2013. Tech rebounded, however, and secured their second straight title, with two games to spare. In the final round, University managed a 6-2 win over Coastal, which was enough to secure their 2015 MPL status through goal difference. Their closest rivals, Nomads, only needed to win, but could only muster a 2-2 draw with Nelson. In Division One, Christchurch United secured promotion to the 2015 MPL after a close battle with Selwyn. For Cashmere, it was another successful season where they also retained the South Island Championship and won the Chatham Cup.
The English Cup is a knock-out competition that is sponsored by Stadium Cars, and features all clubs within the Mainland Football Federation. All games are currently played mid-week (with exception to the final, which is a Saturday afternoon) at the neutral venue of English Park. Currently, Western AFC are the current holders of the trophy after defeating Cashmere Technical 1-0.
The 2015 English Cup commences on Tuesday 12 May with Ferrymead Bays facing Cashmere Technical. A total of 16 teams entered the competition. Included are all Mainland Premier League, and Division One teams (with the exception of Nelson Suburbs, and the Cashmere Technical, and Ferrymead Bays second teams), as well as Burwood, FC Twenty 11, Hornby United, Hurunui Rangers, Nomads United, Papanui-Redwood, Parklands AFC, Selwyn United, and Waimak United.
