The challenge now is to do it all again on Saturday when they tackle the Wests Tigers in Wellington because consistency has not always been a trait of the Warriors.
"We have to get rid of that tag,'' coach Matt Elliott said. "And the only way to do that is to come out with the sort of intent we displayed on Saturday night.
"You can't play aggressively throughout every match. It's just too hard in this competition. The challenge for us is to be prepared to graft hard, particularly at the beginning of halves.
"You are going to have games that, for whatever reason, you come out flat but that's not a reason to lose. The best teams of the last decade, the Melbournes and Manlys, can play flat and win. It's a matter of sticking to your processes and committing to the things that are most important. I know we are heading in that direction.''
There were many individuals who stood out - Jacob Lillyman (155m, 26 tackles), Simon Mannering (112m, 29 tackles), Konrad Hurrell's impact off the bench playing in the middle and Jayson Bukuya and Shaun Johnson who kept Jason Taumalolo relatively quiet on the Warriors' right edge - but it was the collective effort that impressed the most.
They were accurate (they completed their first 14 sets and had another run of 16 consecutive ones in the second half), patient (six consecutive sets) and often kicked early in the tackle count to play the game at the right end of the park (Johnson kicked for a mammoth 504m).
It got a little nervy towards the end after Glen Fisiiahi dropped a routine bomb to let in a try and the Cowboys came close to snatching a late victory but the Warriors wouldn't bend and it was encapsulated by a desperate try-saving tackle by Sam Tomkins and Manu Vatuvei who somehow managed to hold up Tariq Sims over the line.
The Warriors will face a resurgent Wests Tigers side who upset the Rabbitohs 25-16 on Friday night and have won two of their first three.
Feleti Mateo (knee) is a doubt but Matulino should be fit to play.
