New Zealand - Northern League

The first four years (1965–1969)

In the years 1965–1969, before the launch of a National Soccer League, the Northern League was the highest level competition available to the clubs in the northern region. When the National Soccer League was created in 1970, the Northern League became one of its feeder leagues.

In 1997 and 1998, when the National Soccer League operated as an invitation-only summer league, the Northern League again became the highest level club competition available to the clubs from the northern provinces.

Football Championship (2004–2021)

With the demise of the club-based National Soccer League in 2004, the Northern League, now known as Lotto Sport Italia NRFL Men's Premier, became part of the highest level of football league competition in New Zealand for the third time in its history. The league runs between the New Zealand autumn and winter months (April to September), while the New Zealand Football Championship runs between the New Zealand spring and summer months (October to March).

National League (2021–)

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 four top regional leagues (NRFL Premier, Central Premier League, Mainland Premier League and the FootballSouth Premier League) would be formed into the Northern League, Central League, and 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.

The first few season were dominated by Auckland City after replacing sister club Central United at the dissolution of the New Zealand Football Championship. Auckland City won the league three consecutive times in their first three seasons. In the 2023 season, Auckland City and Eastern Suburbs completed the season undefeated. This is the first time, since Eastern Suburbs did so in the inaugural 1965 season, and the first time two clubs have done so in the same season.
