Four teams returned, including champions Hekari United, while three teams withdrew: runners-up Lae FC were expelled from the league after 'bringing the game into disrepute' in the previous year's final,[3] Morobe FC lost their sponsor and were unable to return, missing out for the first time since the league's inception,[4][5] while Eastern Stars also withdrew.
At the end of the regular season, the top four teams advanced to a knockout competition, the winners of which were crowned Champions.
In the playoff semi-finals, which took place on 16 May 2015, Hekari faced Madang FC, whom they had beaten by seven goals less than a month prior.
They would play Lae City in the Grand Final after the regular season runners-up eased past third-placed FC Port Moresby in the other semi-final.
While Hekari picked up third place as a consolation, Lae City won their first title after a one-sided Grand Final, which finished 5–1.
