With the two former league champions, Lae City Dwellers and Hekari United, separated in the new conference system, both sides qualified for the Championship Playoff stage with relative ease from their respective pools, and were joined by Welgris Morobe and Rapatona.
[1] In the Northern Conference, champions Lae City made a flying start with an opening day 7–0 victory over Goroka Gosiha, who would go on to lose all ten of their games.

However, in what was seen by most as a shock, Erema defeated Port Moresby 2–1 while Rapatona secured a win over Gigira Laitepo by the same scoreline, earning qualification ahead of the team from the capital.
Hekari topped the group after a 5–0 victory over Lae on 12 March 2019,[10] with both sides qualifying for the OFC Champions League and the Grand Final, which was to take place a week later.
Despite their previous defeat, champions Lae responded in the Grand Final, securing their second title in a row with a 2–0 victory over Hekari thanks to two goals from Raymond Gunemba.
