The 22-year-old who made his regional debut away to Edinburgh in 2009 has gone on to make 39 appearances and is delighted to have signed an extension.
“I’m absolutely delighted to be staying here, I’m a Cardiff boy, born and bred, and to be offered and sign a new deal is fantastic,” said Warburton.
“I’m only 22 years old and feel there’s a lot more to achieve.
“I’ve only been with the seniors for three seasons and with all the young players such as Bradley Davies, Leigh Halfpenny and Tom James, we’ve got a very bright future.
“I’ve come through with the same bunch of boys in the Academy and we’ve all progressed together so it’s been quite a smooth transition.
“What is exciting is I’ve known some of these boys for six years already through rugby circles and there’s about ten or twelve of us who have come through within a few years of each other, which shows the systems are working.
“About six or seven of us have been capped already.”
Since making his debut on the summer tour of North America in 2009, Warburton has been an ever present feature in the national set-up and he is looking forward to successful end to the season with the Blues.
“I think the play off places is a minimum for us in the Magners League. We want the title and follow up on the silverware we won in the last two years.”
“If we didn’t reach the play offs it would be a very disappointing season but everyone is focused on finishing the season strongly.”
