The 31-year-old former New Zealand prop was due to be out of contract at the end of the season but is eager to finish his career with the Bulls.

Vagana said: "I've been here six years and I want to finish off at this club.

"I have lots of good memories and I'm hoping for a few more now before I do pack it in. I had offers from other clubs but here is like home from home."

Vagana joined the Bulls in 2001 from Auckland Warriors and has made 187 for the Yorkshire club.

He added: "It would have been hard to leave but it's a cruel world. Guys that have been here 10 years had to go last season and it's part of rugby league but I'm just glad I've been given the opportunity to stay."

Bradford coach Steve McNamara was quick to sing Vagana's praises. He said: "Joe is very important to this club in what he does both on and off the field and his form has been outstanding in recent weeks.

"Since the departure of Stuart Fielden I think he has really stepped it up."
