The Crusaders finally made their dominance count as they ground out a 14-8 win over the Lions in a repeat of last year's Super Rugby final.
Trailing 5-0 at halftime in Johannesburg, converted tries to lock Sam Whitelock and centre Jack Goodhue in the space of three minutes midway through the second spell proved decisive.
Elton Jantjes landed a penalty for the fast-finishing hosts but it wasn't enough to prevent them sinking to a third loss from their last four games.
The defending champion Crusaders' fourth win from six lifts them level at the top of the New Zealand conference although they've played one more game than the Hurricanes.
The Lions (4-3) sit atop the overall standings, one point ahead of the leading Kiwis and alongside the Melbourne Rebels (4-2).
