Attempts were made by the PNGFA in the mid-1970s to create a national league, similar to the current National Soccer League, but such a league was considered to be unfeasible due to the high airfare costs that clubs would incur by travelling each weekend. Instead, two competitions were run: The Haus Bilas Cup, which was an inter-district competition, and the National Club Championship, into which were invited the winners and runners-up of the local leagues. The National Club Championship became the de facto highest level of football at this time, and was generally played over one weekend at Easter.
1976–1994: Early years
It appears the first National Club Championship took place in 1976, and was won by Mopi FC from Lae. The early years were dominated by sides from Lae and Port Moresby, with Mopi picking up a second title in 1981 and Buresong FC, also from Lae, winning in 1982 and 1984, while four Port Moresby-based sides won the remaining five competitions played between 1976 and 1987: Germania FC, Tarangau FC, Guria FC and Westpac FC. Due to their victory in 1986, Guria FC qualified for the inaugural Oceania Club Championship held in 1987 in Adelaide, Australia. The side lost their opening qualification match and progressed no further. Guria Lahi became the first side outside of the two soccer strongholds to win the National Club Championship, in 1988. Playing against two-time champions Buresong in the final, the Lahi-based team won 1–0. In 1989 and 1992, Guria FC won their second and third titles, claiming the record for most championships, which would stand until 1999.
1995–2005: Pre-NSL growth and further OFC qualification
In the four years from 1995 to 1999, the competition was won by one side – ICF University. The side won their first title in 1995, before final victories against Telikom Lae in 1996, Babaka in 1997, and Blue Kumuls Lae in 1998 gave them the record for the most domestic titles at that time. However, in 1999, Guria Lahi once again broke the dominance of capital-based sides, beating Port Moresby-based Rapatona 2–1 in the final. With the prospect of the 2001 Oceania Club Championship taking place in Port Moresby, for the second time there was an opportunity for the national champion to qualify for a continental competition. Guria Lahi reached the final once again, but were defeated 3–2 by Unitech, with the university-based side qualifying for the Oceania Club Championship as a result. The side won two out of their five group matches and finished fourth in the group. The next five editions of the competition were won by Sobou FC, who picked up their first title in 2001 with a 3–1 victory over four-time champions ICF University. In 2005, they picked up their fifth title, breaking University's record of the most national championships. As national champions, Sobou qualified for the 2005 and 2006 editions of the OFC Club Championship, but failed to register any victories in the finals.
2006–2008: Cancellation
With the launch of the semi-professional National Soccer League, the PNGFA decided to run both competitions alongside each other in 2006, with the winner of each going head-to-head in the "Overall Championship", a two-legged tie, the winner of which would qualify for the 2007–08 OFC Champions League. Despite losing to them in the group stage, University defeated Sobou on penalties in the final, clinching their fifth title and equalling Sobou's record, before defeating NSL champions Hekari United 4–2 on aggregate, thus qualifying for the Champions League. However, they were unable to get beyond the preliminary round. The 2007 edition of the National Club Championship didn't materialise, while in 2008, the title was won by Sunammad FC, the first national club title won by a club from West New Britain and from the New Guinea Islands Province. Since 2008, the competition has not been held.
2019: Revival
In June 2019, it was announced that the competition would be revived. Under a new system, regional competitions took place across all four regions of the country – Northern, Southern, Highlands and Islands – in June and July 2019, before the winners came together in Port Moresby for the finals in September. The champions were Mungkas, who picked up their first championship with a 1–0 victory over City United of Lae.
