Wayne Culverwell opened the scoring for the visitors before Rory Binnie equalised in the second half.
Curtin�s new central defensive pairing of Francesco Gerace and Albert Bucchino were rarely troubled as the home side did most of the attacking.
Curtin stalwart Eddie Tikoft and Jon Krawec combined well with youngster Rob Keegan in the middle of the park for the home side while Dilip Thapa and Nathan Smith caused havoc out wide.
Kingsway took an early lead inside five-minutes as Mackenzie Ferguson saved a soft penalty, but Culverwell prodded the rebound home.
From here, Curtin grew into the game but finished wastefully with Krawec, Binnie and Tikoft all seeing efforts fly off target.
The home side could not find a way to break down a resilient Kingsway side.
