NRL veteran Issac Luke has joined the St George Illawarra Dragons on a one-year deal.

Luke, 32, will enter his 14th season as he looks to add to his 271 games in the NRL.

The hooker has previously played for the South Sydney Rabbitohs and New Zealand Warriors, while he is also a 43-time New Zealand international.

"Everyone is already aware of Issac's career in regard to his longevity," Dragons director of rugby league pathways and list management Ian Millward said in a statement on Tuesday.

"Issac has walked the path of the NRL over a long period of time now and will be great for our squad.

"To have a really established back-up player of his calibre is exciting. Our coaching staff were keen to have him on our roster with plans in mind regarding how they'd like to play him, which have already been discussed with Issac as well as Cameron [McInnes].

"With Issac now on board, we have 25 players on our roster [and] 23 of them have played NRL and while that includes those who have just received their first taste of first grade like Jackson Ford and Jason Saab, we are pleased with Issac's injection of experience."

The Dragons struggled during the 2019 season, winning just eight games to finish 15th.
