Tango should have put the Aces ahead when he cleverly went round the edges of the defence but was thwarted by a good save from NZ Masters keeper Geoff Williamson.
Otumoetai were resilient at the back, with Hugh Gilmour and Garrick du Toit dominant, but getting the ball into the goal proved to be difficult.
The opening goal finally came after Hayden Bruin, one of three brothers in action, produced a pin-point pass for Andrew Bingham to turn in for a 1-0 lead at the break.
The second goal came quickly after the restart, with Tyler Bruin doing the hard work to set up his brother Hayden for an easy finish.
Cory Bruin reacted quickly to a deflected back pass to make it 3-0 as the Aces struggled to keep up with the intensity of the Otumoetai attack, freshened by six replacements.
The Aces even tried a quarter field press but were powerless to stop a sweeping move that started deep in the Otumoetai half. Accurate passing from Gilmour and promising 15-year-old Liam Burn setting free the Bruin boys, with Hayden scoring his second goal.
Munro Stewart added a final goal to make it 5-0 but the Aces did have a late flurry forcing two consecutive penalty corners without any luck.
