But as is often the case, the Steelers kept things interesting by just dropping their intensity at an inopportune moment.
The game never really opened up as the penalty count topped 25, referee Glen Jackson pinging both sides with alacrity.
Fans were treated to the bizarre sight of Wellington blindside flanker Vaea Fifita hurdling Piers Francis at full pace down the left flank. It had no real impact on the match but it lit up Twitter for a time.
The Lions had the, ahem, lion's share of early ball and field position but could not make the advantage count after an initial lineout-driven try to hooker Leni Apisai.
They were not helped by the sin-binning of lock Isaia Walker-Leawere for not rolling away from a ruck when he was pinned. Apisai, incredibly, scored another from an identical lineout set-up.
Wellington replacement first-five TJ Va'a was stretchered off with what looked a painful knee injury.
The Steelers face Premiership union Taranaki on Wednesday at Pukekohe, while Wellington host Bay of Plenty on Friday.
