That was as good as it got for the Lions, with a howler from the Lions to open the second half seeing the ball spilt straight into the path of Ben Lam, who raced away to score. Five minutes later - after a Barrett penalty - he had a double, with help from an Ardie Savea offload, and the Hurricanes lead 25-10.
The Lions had a try ruled out due to obstruction, then cut the gap to 25-17, but the Hurricanes were up to the task, with a Dane Coles double sealing a win which should see the Hurricanes finish second on the ladder.
Now on 49 points after the bonus-point win, only the Jaguares - on 41, with a game in hand later this morning - can catch them. Now, the Hurricanes will prepare for the Blues at home next weekend, before getting to stay in Wellington for their quarter-final.
Hurricanes 37 (Ben Lam 2, Dane Coles 2, Ngani Laumape tries; Jordie Barrett 3 cons, 2 pens)
Lions 17 (Aphiwe Dyantyi 2 tries; Shaun Reynolds 2 cons, pen).
HT: 10-10
