NRL: Jazz Tevaga frustrated with 'mentally weak' NZ Warriors before Melbourne Storm showdown

There's no denying the frustration within the NZ Warriors camp, as another NRL season slips away, with their campaign typified by their defeat to Canberra Raiders.

Each week, the same themes appear - mistakes at key times, individual errors, lost momentum and an inability to respond to adversity. 

The Warriors have shown glimpses of their potential, especially in their homecoming win over Wests Tigers, but forward Jazz Tevaga is frustrated.

"It's a tough one," he said. "I can't put it down to one thing - what I will say is we're pretty mentally weak.

"When something goes against us it has a snowball effect."

Like any high-performance, high-pressure environment, tensions can boil over when things aren't going your way. 

For the Warriors, Tevaga believes that's been magnified in recent weeks. 

"That's just built-up frustration, then guys start spraying each other," he said. "There have been toxic sprays on the field and it's something we have to get out of our game.

"I think the leaders have to come together - the more experienced players. We just have to get the team back on track and it's just getting back into our process.

"We've lost a bit of resilience this year within us and when one thing goes wrong, it snowballs. We're struggling to learn how to turn that around and defend our errors."

All of this will be tested again on Friday night, when they welcome Melbourne Storm to Auckland's Mt Smart Stadium. 

On a four-match losing streak themselves, Melbourne will look at this encounter as an opportunity to get their season back on track. 

Veteran Shaun Johnson - who will again pair with Chanel Harris-Tavita in the halves, with fullback Reece Walsh reinstated - agrees the Warriors need to be stronger when things go against them.

"When you got it, you got it, but when you're against it, you certainly feel it," Johnson explained, when asked if he could feel momentum slip away during games. 

With a healthy lead and all of the momentum going into the break against Canberra, the Warriors were rocked in the second half - particularly by the boot of Raiders ace Jack Wighton.

"Those kicks shifted the game," said Johnson. "We still had an opportunity, as a collective, to stop it and that's where we fell short.

"Mistakes get made, but I just think, at the moment, our response isn't up to scratch. We're not collectively buying into what we need to do to get the ball back. 

"Just because they kick a 40/20 shouldn't mean they score a try is what I'm trying to say. That's where we're at as a group."

Johnson, as a senior player and a glass-half-full type of character, sees the growth from recent games, as well as an opportunity for an upset at home this week. 

"I'm not happy with the result, I'm not happy with the second half, no, but it gives me confidence and belief we can match it with those sorts of teams."

The Warriors will need all of that belief in bucket loads, with a fired-up Melbourne ready to storm Mt Smart.
