The Penrith Panthers have reportedly alerted the NRL about potentially concerning behaviour from a section of Warriors fans ahead of their elimination final in New Zealand.
The Sydney Morning Herald have reported that the club flagged an unofficial Warriors Facebook fan page that correctly identified the Pullman Hotel in Auckland as the Panthers' accommodation.
In the thread titled "help our boyz", members of the "New Zealand Warriors Till I Die" group have been encouraging each other to disrupt the reigning premiers preparations in the build up to the clash.

"ATTENTION ALL WARRIORS WHANAU," the subject line read.
"It's our job as fans to help our boyz as much as possible.
"Fireworks, burnouts and screaming outside the hotel is highly recommended anytime between 1-4am on Saturday."
The stunt raised concerns amongst Penrith officials, with their CEO Matt Cameron speaking out about the issue.
"We’re aware of the post that has been circulating," he said.
"I’m all for the fans being passionate about their team. I would expect both sets of fans to act responsibly while still supporting their clubs."
Despite the potential for major disruption, the club is reportedly yet to request that their accommodation be moved.
Warriors CEO Cameron George reassured his opponents, stating that the Auckland-based club has "very responsible fans."
"They’re excited about the weekend. Penrith don’t need to feel unsafe or anything in regards to that with their hotel," he said.
35,000 members are currently associated with the page, leaving questions about how widespread this message has been received and how legitimate the calls to action could become.
