They allowed an error-riddle New Zealand Warriors side to run over the top of them - again failing to score in the second half of their 21-20 golden-point loss at Redcliffe on Saturday.

It was a Shaun Johnson field goal in extra-time that completed the win for the Warriors.

That came after a controversial penalty awarded by the bunker against Raiders prop Corey Horsburgh, who was put on report for high contact on Warriors counterpart Matthew Lodge.

Warriors fullback Reece Walsh calmly slotted the penalty with just two minutes remaining to send it to golden point, where Johnson capitalised on Raiders hooker Tom Starling's forward pass that gifted the home side field position.

It meant the Warriors turned around a 60-point loss to the Melbourne Storm last week to come away with the two points.

But it was how the Raiders let the game get to that point that had Stuart fuming.

It was the third match in a row the Raiders failed to score in the second half.

"That whole second half was undisciplined, lacked any quality execution. It was very disappointing," Stuart said.

"I'm glad they were as bad as us.

"It doesn't matter now [about the penalty against Horsburgh]. It should never have got to that.

"Publicly I'm lost for comment in regards to the quality of that football in the second half and for any loyal fan that we've got left I feel really embarrassed and sorry for them."

However, North Queensland Cowboys legend Brent Tate was scathing of the decision.

"I can't believe it was a penalty. We've got the bunker interfering in games," he said on Fox League commentary.

"I don't know what to say to be honest. I didn't think it was a penalty at all, a very soft one ... and as a result we've got players lying down."

While Horsburgh's unlikely to face any serious sanction from the match review committee, the Raiders will be sweating on their review after both Jack Wighton and Joe Tapine were also put on report.

Wighton was cited for a lifting tackle on Reece Walsh and Tapine for a facial on Murdoch-Masila.

Somehow Murdoch-Masila escaped sanction for an elbow to Tapine's head.

Lodge was also put on report for an elbow on Corey Harawira-Naera, while the Warriors lost Jesse Arthars at half-time with a shoulder problem.

Warriors coach Nathan Brown felt a penalty and being put on report was a fair outcome when asked about whether Lodge was lucky not to be sent off.

"It certainly went a bit awkward there, but I don't think he went out deliberately to do it," Brown said.

"I always look at the action, is it a bit stiff, and I couldn't argue that it shouldn't be a penalty and he's on report and that if that was one of their players that did it I would've been happy to cop a penalty and report and see where it takes itself."

It had started brightly for the Green Machine, with centre Matt Timoko opening the scoring after Wighton put him through a hole.

The Raiders middles were all firing - especially Adam Elliott, in his best game in lime green.

He was a surprise starter at hooker, with Starling relegated to the bench, and he produced a number of mazy runs out of dummy half - before switching to a more familiar role in the middle.

Then he continued to shine with his hard running and he produced a great offload for Hudson Young to score.

Raiders enforcer Josh Papalii also started well, running for 106 metres in his opening 20-minutes stint, as Stuart showed more faith in his bench.

Raiders fullback Jordan Rapana struggled, with his error leading to Warriors centre Adam Pompey scoring.

He also slipped after copping a tough bounce from a Daejarn Asi chip, allowing Warriors winger Viliami Vailea to score his maiden NRL try.

But the home side's own errors allowed the Raiders to restore their eight-point lead by half-time Wighton capitalising on an Eliesa Katoa mistake.

It was almost a case of both sides going error for error in a scrappy second half.

The game did threaten to explode though, with tempers flaring when Tapine and Murdoch-Masila came together.

Asi's impressive Warriors' debut continued, putting Euan Aitken through a hole, and it looked like Johnson might have scored the winning try only for it to be ruled out due to obstruction.

Raiders acting captain Wighton said they needed to learn how to win again.

"It's becoming too common," he said.

"We've got to find a way to become winners again. At the moment we just keep letting it slip.

"I'm lost for words. It's something we have to look at tomorrow and we have to move on fast."
