The OFC Champions League, also known as the O-League, is the premier football competition in Oceania. It is organized by the OFC, Oceania's football governing body. It has been organized since 2007 under the current format, following its successor, the Oceania Club Championship. Two teams from the ISPS Handa Premiership participate annually. Four O-League titles have been won by teams from New Zealand. ASB Charity Cup The ASB Charity Cup was introduced in 2011 as a season opener played the weekend before the first matches of the ASB Premiership season. The fixture pits the ASB Premiership Grand Final winner against the best performing New Zealand team in the OFC Champions League. However, when the same team fills both categories as Auckland City did in 2014 and 2015 the ASB Premiership runner-up qualifies for Charity Cup. ASB Phoenix Challenge The 2010–11 season saw the introduction of the ASB Challenge Series. This was an individual friendly competition in which the eight Premiership teams competed against a reserve team attached to Wellington Phoenix, a New Zealand-based team playing in the Australian A-League. The ASB Phoenix Challenge was discontinued after the 2010–11 season but reinstated for 2012–2013, its last appearance. White Ribbon Cup The White Ribbon Cup, is a knockout cup competition run by New Zealand Football. The 2011–12 season will be the inaugural season of the NZF Cup. It was established in 2011 to provide regular football for the six clubs not participating in the Oceania Champions League and runs in conjunction with the ISPS Handa Premiership regular season. National Youth League New Zealand Football additionally ran the National Youth League, a competition for the youth teams for each of the clubs in the New Zealand Football Championship. It was held between October and December, and consisted of each team playing each other once; the fixture list mirroring that of the senior league. The team with the most points at the end of the season became the champions. The final champions were the youth team of Auckland City. After a review by New Zealand Football of all their national competitions, it was decided to end the national youth competition with its last season being 2019. In the last season of the competition, Auckland City won its seventh title as well as winning three in a row from 2017 to 2019 to finish as champions of the competition.
