"We're asking anyone who knows anything about this incident to do the right thing and report it to police immediately so we can return the gear to the team."
Vodafone Warriors CEO Cameron George told the Herald the team was devastated by what had happened.
"All the playing jerseys from our historic win over the Raiders have been stolen and they obviously hold special significance for the guys.
"Then we've also had a fair bit of expensive equipment, including the players' GPS units and a video drone used for training that has also been stolen. All up it's worth thousands of dollars.
"It's taken the gloss off what was an incredible weekend but it's just another challenge and one we are certainly not going to let distract us from making our fans even prouder in the coming weeks."
