Penrith Panthers can confirm Peta Hiku has been immediately released from the remainder of his contract to pursue an opportunity in the UK Super League.
The 24-year-old outside back joined the Panthers from Manly ahead of the 2016 season.
"Peta is an international-class footballer and has been an extremely popular member of our club," Panthers Executive General Manager Phil Gould AM said.
"Unfortunately with the emergence of several of our young players and the way our team has developed, we can’t fit everyone in the team each week.
"From a salary cap perspective we always knew someone would probably have to move on.
"Peta received a great offer from a strong club in the UK and it presents a wonderful opportunity for Peta and his young family.
"We wish them well and sincerely thank Peta for his time here at the Panthers. He is always welcome back at our club."
Hiku departs the Panthers having scored six tries in 20 NRL appearances for the club.
