Halfpenny has scored 16 tries so far in his Blues career, and almost 200 points, including a try for the Blues in the final of the 2010 Amlin Challenge Cup Final against Toulon in Marseille.
Halfpenny was included in the British & Irish Lions squad for the tour to South Africa in May 2009 but had to return home from the Lions tour due to a recurrence of a thigh injury.
Speaking of his decision to sign a contract extension with the Blues Halfpenny said,
"I'm really pleased to have extended my stay at the Blues."
"It's a great club and I had no doubt that this is who I wanted to sign with and happy that we have come to an agreement."
"I've not been tempted to play anywhere else as it's a very ambitious club and the quality players we have here, with some good youngsters coming through, the future looks very bright."
"You couldn't ask for better training facilities, which are fantastic and for me there's no better place for a rugby player to be."
"We are seeing the Welsh talent coming through and it's great that they have decided to stay with the region."
"We won two titles in the last two years but we still have ambitions of winning more in the future which is why most of the players have extended their contracts."
At 6ft 6ins tall and weighing over 19st Bradley Davies is a formidable force on the rugby pitch. Hailing from Llantrisant, the second rower captained Wales Under-19 to the Grand Slam in 2005 and the 2006/07 season saw him established in the senior Blues squad and he's gone on to make 79 appearances for Cardiff Blues.
His energy and commitment around the field has impressed the Blues faithful and in the summer of 2008 he was selected in the Wales squad to tour South Africa but was not able to play due to injury. During the 2009 Six Nations Championship Davies made his Wales debut as a late replacement against Scotland.
Bradley Davies said, "It's great news to have signed, not only for me personally, but for the rest of the boys who have signed also."
"It's nice that we have got a core of young players who have extended their contracts and can drive the region forward."
"I think our academy system is showing it's worth now, a lot of the boys have stepped up and played at a high level, either Heineken Cup, regional rugby or international level."
"There's great work being done at the Academy in Trefforest and the region is bearing the fruits of that."
Chris Czekaj, who is on course to play his 100th match for the Blues against the Ospreys this weekend added,
"I've been six seasons with the Blues now and I'd be stupid to want to move with the progress that the team has made over the last few years."
"I've really enjoyed the move from wing to full-back this season and I prefer playing full back now to be honest, so that's where I see myself from now on."
"I find you get more ball at full-back and I get to use my kicking game a lot more. You also get to see a lot more of the attacking opportunities from there."
"Dan Fish has come through this season and put in some good performances, and he's taken his chance well so it's good to have that type competition along side a lot more established player such as Ben Blair."
