Wakefield's Cook Islands international Tinirau Arona has signed a new contract for 2019.
The 29-year-old back-row forward has been a model of consistence for Trinity since he joined them from Cronulla ahead of the 2016 season and is one of only four ever-presents so far this year.
"It's really good news," said Wakefield coach Chris Chester. "I'm pleased for T. He's been very good, certainly this last six weeks and has been a consistent performer for the club over a number of years.
"To get something sorted is massive for the club."
Arona said: "I'm over the moon. It's like a weight has been lifted off my shoulders.
"Wakefield is my home and I'm happy to call it home for another year."
