Police have released CCTV stills showing the robbery of gear belonging to the Warriors which was stolen from a vehicle in Torbay.
At about 4.10am on Monday, two offenders broke into a van containing Warriors players' uniforms, GPS units and a video drone among other items.
The gear-laden unmarked van was parked outside a staff member's house on Auckland's North Shore when it was broken into.
Police now have images of the alleged offenders and the vehicles used in the burglary and would like to hear from anyone who can help identify them.
Detective Sergeant Dean Miles said somebody would be able to recognise them from the images.
"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."
