Stand-in Wests Tigers skipper Benji Marshall plans to revise the way he talks to referees in the wake of his costly sin-binning against Brisbane last week.

Marshall was given a spell on the sidelines during a crucial period late in the 20-18 loss at Campbelltown Stadium last Friday night, the New Zealand Test captain paying the price for a string of penalties against the home side.

Tigers coach Tim Sheens was left fuming at the decision, believing Marshall bore the brunt of both sides' indiscretions.

But with the `c' beside his name again this week with Robbie Farah in camp with the NSW side, Marshall said he would seek to build a better relationship with whistleblowers Gavin Badger and Brett Suttor when the Tigers travel to Auckland to face the Warriors on Sunday.

"Just the way (I) talk to them - some of them are a bit hard to approach - but I think I let me worrying about what the referees were doing affect my game too much," Marshall said of his run-in with Jared Maxwell and Ben Cummins.

"You say what you've got to say and get on with the job - I'll still be doing the same job this week, I just won't let it affect my game this time."

Asked if it meant less talk with the men in pink, Marshall said: "Not so much less talk but less bad talk where I let the negativity get the better of me."

Coming off three straight losses, the Tigers can ill-afford to stretch it to a fourth given they are already three points behind eighth-placed South Sydney.

Making it harder for the Tigers to accept their poor ladder position is the fact they could easily be sitting on top of the ladder with 16 competition points given the greatest losing margin in all three of those losses was just two points.

"We're looking at the (Warriors) game as sort of a must-win - it's not going to be the end of our season if we do lose - but ideally we'd like to win," Marshall said.

"We can take the positives out of it that we're not playing that bad - a couple of games that we should have won we didn't and if we can take that confidence into the game then I think we're a good shot."
