Warriors hooker Issac Luke.

The Warriors have announced a double retention coup with veteran Issac Luke and back-rower Isaiah Papali'i inking new deals to remain at the club.

Kiwi international Luke took to Twitter on Wednesday to announce he would suit up again for the Warriors in 2019, while Papali'i has been secured until at least the end of 2020.

Luke's fourth Warriors campaign will coincide with the club's 25th season in the NRL.

"It's good to have the contract all sorted out," he said. "We always wanted to stay in New Zealand, my wife and the kids. I'm really happy here at the club and I'm pleased I have another season with the boys."

Warriors coach Stephen Kearney was thrilled to have Luke locked in.

"We wanted Issac to stay. It was just a matter of sorting out the details," he said.

"Now we look forward to him making a big contribution to the side next season."

The 31-year-old played 23 of the Warriors' 25 games this year, scoring six tries while averaging 71 minutes per match, 72 metres and 31 tackles a game. He had 114 dummy-half runs, third most in the NRL behind fellow hookers Damien Cook (Rabbitohs) and Cameron McInnes (Dragons).

Late in the season, Luke reached the 250-game career milestone while taking his club appearances tally to 66.

Meanwhile, Papali'i has extended for another season after originally contracted until the end of 2019.

The Warriors back-rower cemented his spot in Stephen Kearney's side in 2018 and was recently picked for New Zealand's Test campaign against Australia and England over the next six weeks.

"Isaiah is a great young prospect who has quickly established himself at NRL level," Kearney said.

"He's a wonderful example to players aiming to make it into the NRL coming through our system. He really impresses with his attitude and resilience."
