The top spot is currently owned by Waitakere, who claimed a 3-1 victory over Southern United on Saturday to go two points clear of Auckland City and Wellington. The fourth and final playoff spot is currently occupied by Eastern Suburbs, who defeated Hamilton Wanderers 3-1.
Auckland have a game in hand on their fellow playoff contenders, but missed a chance to share top spot after a 2-2 draw with Canterbury United.
Ramon Tribulietx's side seemed to have sealed a tight victory when Alfie Rogers gave them a 2-1 lead in the 84th minute, but Andre De Jong was dragged down in the box in injury time, giving Canterbury a last-gasp penalty.
The initial effort was saved by City goalkeeper Enaut Zubikarai, but the linesman ruled he did so illegally, and the re-take was tucked away by Tom Schwarz to rescue a late point.
In the other game played this round, Tasman United picked up their fourth draw of the season, holding the Wellington Phoenix Reserves to a 1-1 stalemate.
The youthful Phoenix side had a chance to win the game with a penalty in the 92nd minute, but Tasman goalkeeper Tom Fawdry pulled off a fine low save to make up for an earlier error and maintain a point for his side.
