Penrith Panthers can confirm Corey Harawira-Naera will be granted a release from his contract to take up a long-term deal with another NRL club in 2019.
The 23-year-old forward remains contracted to Panthers for the remainder of the 2018 season.
Recruited from his native New Zealand, Harawira-Naera progressed through the grades at Panthers and was a member of the club's premiership-winning NYC side in 2015.
He made his NRL debut in Round 4, 2017, and has gone on to play 44 NRL games and score 13 tries.
"The decision to allow Corey a release from his contract was a difficult one," Panthers Executive General Manager Phil Gould AM said.
"Firstly it's a matter of future salary cap management for our club. Secondly it is such a wonderful opportunity for Corey with his new club.
"Corey came to us from New Zealand as a teenager and developed through our junior pathways and house-parent program. He is now a quality NRL regular with obvious representative potential.
"He has been a very popular member of our club and we are sad to see him leave. Unfortunately it is just a fact of life in rugby league today under the salary cap system.
"We wish Corey all the best for his future and we will follow his career with great interest."
