Both Newcastle and Parramatta are chasing off-contract hooker Issac Luke but the Warriors have put a halt to player contract negotiations during their NRL finals run.
The Warriors want to retain Luke and the Kiwi international also wants to remain in Auckland, but the Knights and Eels have expressed interest in luring him across the Tasman for next season.
The Eels are keen on signing Luke to help them in their plans to rebuild after finishing with the wooden spoon following Saturday's final round 44-10 walloping at the hands of the Roosters.
Newcastle are also eying Luke as a potential signing as they consider options to replace Slade Griffin who suffered his fourth season-ending knee injury in July. The Knights also have young Kiwi Danny Levi on their books but need to bolster their No 9 stocks, while they are also in talks to re-sign other members of their squad.
Versatile Warriors bench forward Jazz Tevaga is another free agent currently weighing up approaches from rival clubs, but like Luke hopes to extend his time in Auckland.
