Hawke's Bay's first half highlight was a short ball from lock Geoff Cridge which sent wing Robbie Fruean over in his comeback match. Ryan Tongia blitzed the cover for the second try. But there were too many missed one on one tackles to mount any concerted pressure on the visitors.
No 8 So'otala Fa'aso'o carried well for the Steelers, while first five Piers Francis landed his kicks, including four penalty goals in the second stanza, racked up 23 points and slotted the first drop goal of the 2016 competition.
Magpies lock Ross Filipo saw just over 15 minutes of action and must be one of the oldest debutants in union history at 37.
The Magpies are back into Premiership action next Wednesday hosting Auckland, while the Steelers are at home next Friday for a crossover clash with Wellington.
