It also continues a remarkable season for Auckland City, who are unbeaten in the Northern League (with a draw against Hamilton Wanderers their only blemish) and will contest the Chatham Cup semifinal against Wellington Olympic on Sunday.
In difficult blustery conditions at Ngahue Reserve Auckland City took the lead in the 12th minute through a Cameron Howieson penalty.
The award was hotly disputed and didn't seem an obvious penalty, as defender Adam Mitchell was dragged down at a corner.
That led to a significant delay – as the AS Venus players disputed the call – but Howieson did well to maintain his composure and bury the spot kick into the bottom right hand corner.
The home side extended their lead in the 29th minute after a quick transition.
Ryan De Vries surged in the penalty area, before the ball broke to Gerard Garriga, who finished into an empty net.
They went close to a third on the hour mark – thwarted by double saves from the Tahitian goalkeeper – before Auckland custodian Conor Tracey produced a sharp stop of his own in the 73th minute.
Tade's goal provided an appropriate finale, as the Argentinean striker buried a neat half volley from six yards.
