Impressive, unexpected results were a trend throughout the league this weekend, with Southern United reeling off their third straight win, their first three-game winning streak since 2011.
They toppled Canterbury United 3-1, coming from 1-0 down after 55 minutes to claim a significant scalp.
Also significant was Hawke's Bay United's performance, triumphing over Eastern Suburbs in a 6-3 goalfest to jump into sixth on the ladder.
Suburbs were picked by pundits to pick up three points which would have seen them join the three leaders, but a poor second half performance has left them clinging to fourth spot on the ladder, having gone four games without a win.
They have been jumped on the ladder as a result by crosstown rivals Waitakere United, who are on a five game unbeaten run.
Chris Milicich's men defeated Hamilton Wanderers 2-1, with German striker Pascal Reinhardt scoring the winner in the 79th minute to send the three-time champions back into a share of the league lead.
They trail Team Wellington on goal difference, who took down the Phoenix Reserves 3-1 on Saturday.
