After two losses on the trot, Pāpāmoa FC would have been confident of getting back to winning ways when Ōtūmoetai visited Gordon Spratt reserve on Saturday.
Ōtūmoetai had had a miserable start to the new NRFL Southern Conference, failing to gain a single competition point in five starts.
But form often goes out of the window in local derbies, and within 10 minutes the visitors were 2-0 up thanks to goals from Jack Boland and Chaz Picton.
Pāpāmoa gave themselves something to build on with a headed goal from Colm Kenny off a free kick just before the halftime break.
But Ōtūmoetai’s defence held firm and their attack restored the two-goal advantage, Picton getting his second on 58 minutes.
