Edward Hunuiehu scored his eleventh goal of the season to give Kingz the lead in the first half.
Papua New Guinea (PNG) international Nigel Dabinyaba scored his first goal for Kingz later in the second half to give his side a two-goal lead.

The defeat saw Laugu drop to the seventh position with 15 points.
They had the golden opportunity to level the score and at least get a point from the match when Laugu captain Atkin Kaua won a late penalty in added time but his attempt from the spot was saved by Kingz custodian Erick Peter.
