Unfortunately for FC Whangarei, their four-man erect wall was not enough to stop a lofting shot by Marcus Mulhearn.
From the restart FC Whangarei made their way into Tikipunga territory, where they were awarded a corner.
A Jason Teal header deflected off Crowley, which wrong-footed Tikipunga's goalie William Morunga, resulting in the match winner.
