New Zealand Football Championship

The New Zealand Football Championship was created as a replacement to the former New Zealand National Soccer League, a tournament involving clubs from the regional governing bodies of New Zealand Football. The NZFC was to be run as a summer league involving new clubs created solely for the new competition, with these new clubs being run jointly by existing winter clubs. The only exception to this was Napier City Rovers, whose summer club would be rebranded Hawke's Bay United during the second season, to be operated jointly by other clubs in the Hawke's Bay region.

Eleven groups bid for franchises, with the successful bids being announced on 7 April 2004 as Auckland City, Canterbury United, Napier City Rovers, Otago United, Team Wellington, Waikato FC, Waitakere United and YoungHeart Manawatu, with Olé Madrids, East Auckland and Team Bay of Plenty being excluded. Unhappy at their exclusion, the Olé Madrids bid team took New Zealand Soccer to court, suing for damages and demanding inclusion in the competition, claiming that, whilst they met NZ Soccer's criteria for inclusion, other successful bids did not. The case was dropped by the Madrids team eight days before the commencement of the first NZFC season. The Olé Academy, previously having had a relationship with Team Wellington, currently holds an exclusive partnership with current league side Eastern Suburbs. East Auckland also considered legal action, however this was not pursued.

The first match of the competition was on 15 October 2004, with Auckland City defeating Napier City Rovers 3–1 at Park Island, Napier. Auckland City were also crowned the inaugural NZFC champions after defeating Waitakere United 3–2 in the final.

The second season saw Napier City Rovers rebrand and reorganize their NZFC team as Hawke's Bay United, forming an amalgamated franchise with other local clubs. It also saw the first instance of a NZFC team winning the O-League, with Auckland City FC defeating Tahitian team AS Pirae 3–1.

At the conclusion of the 2006–07 season, New Zealand Football granted three-season licence extensions to seven of the eight franchises – all but YoungHeart Manawatu, who had to reapply due to concerns over the club's financial and organisational situation. However, YoungHeart eventually earned reinstatement after beating out four rival bids – one based in Gisborne, one from North Shore City, and two from Manukau. Olé Madrids also applied for the licence; however they withdrew early.

On 2 September 2010, New Zealand Football announced a five-year sponsorship agreement with ASB Bank resulting in the rebranding of the New Zealand Football Championship to the ASB Premiership.

In 2013, after a review of the competition by the ASB Premiership review committee, YoungHeart Manawatu was dropped from the competition after finishing last in the previous three seasons. New Zealand Football also confirmed that a team composed of New Zealand players born on or after 1 January 1995 would take Manawatu's place in the Premiership for at least two seasons. The addition of the team – to be known as Wanderers SC – was to provide adequate preparation for New Zealand's U-20 players for the upcoming 2015 FIFA U-20 World Cup which will be hosted by New Zealand. Much confusion surrounded the initials "SC" in the Wanderers' name, as no official explanation was given as to what they stood for. It wasn't until after their first match that coach Darren Bazeley finally revealed that "SC" stood for "Special Club", saying "it acknowledges this team has arisen out of a special situation and was specially formed for the purpose."

The 2014–15 season saw the Premiership expand to nine teams for the first time in its history. Wellington Phoenix Reserves was added to the competition to provide game time for the members of the Phoenix squad who are not playing frequently for the first team in the A-League. Restrictions were also put in place for all clubs requiring that at least 50% of match day squads are players who are eligible to play for the All Whites.

After 11 full seasons, only Auckland City and Waitakere United have been crowned Premiers or Champions, with Auckland City adding their sixth premiership and sixth title in the 2014–15 season. This trend was bucked, however, in the twelfth season of the competition, as Team Wellington defeated Auckland City 4–2 after extra time in the final. The 2018–19 saw Eastern Suburbs crowned as champions for the first time, becoming the first club to win the NZFC and the New Zealand National Soccer League.

In December 2015 it was announced that the league would be expanding to 10 teams for the 2016–17 season with Eastern Suburbs from Auckland, Hamilton Wanderers from Hamilton, and Tasman United from Nelson joining the league, while WaiBop United would exit the competition.

In September 2016, it was announced that the expanded league would be rebranded as the Stirling Sports Premiership.

In March 2017, it was announced that the league would be rebranded as the ISPS Handa Premiership, due to a three-year sponsorship deal with ISPS Handa.

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.
