All Black forwards Kieran Read and Sam Whitelock, have re-signed with New Zealand Rugby for another four years.
They have also recommitted to the Crusaders until the end of 2017, which is a major-boost for the Christchurch-based Super Rugby side.
The deal was announced today by New Zealand Rugby chief executive Steve Tew at Read's University of Canterbury Rugby Club in Christchurch.
"This is a significant re-signing for New Zealand Rugby with the tenure of the players' contracts covering two major rugby events - the rugby World Cup in 2015 and the British & Irish Lions tour to New Zealand in 2017. Kieran and Sam have been outstanding in recent years and we are delighted to have them recommit to New Zealand. For them to commit to New Zealand for such a long time I think is also a credit to the environment that both the All Blacks and Crusaders have created which makes players want to stay,'' Tew said.
Read, 27, has been in outstanding form at No 8 for the All Blacks this year.
"The All Blacks and Crusaders have some exciting things coming up over the next few years and I'm really looking forward to being part of that. I love playing for both teams. The time is right to commit to New Zealand long-term, doing the right thing for my family played a big part and I'm incredibly happy with the decision.''
At 24, Whitelock has already amassed 47 test caps since making his debut in 2010 and quickly cemented his place as one of the starting locks in the All Blacks and Crusaders.
"Playing for both teams is a dream come true for me and I am really enjoying my rugby at the moment. I feel I am constantly learning and developing my game at the highest level and knowing that I will continue to do that in New Zealand over the next four years, playing alongside my mates, is an awesome feeling. There are some exciting times coming up for both teams,'' Whitelock said.
All Blacks head coach Steve Hansen said: "The fact that two world-class players in Kieran and Sam have re-signed for four more years is a huge positive for the All Blacks. Not only are they part of the current success of the team, but it means we have a nucleus of experienced players to take the team into the future beyond 2015, which is fantastic. It's also great news for All Blacks and Crusaders fans, knowing that both players have committed to New Zealand rugby in the long-term.''
Crusaders head coach Todd Blackadder added: "These are undoubtedly two of the best players in world rugby at the moment. More than that though, they are both inspirational, committed team men who bring so much to the Crusaders environment.''
Read and Whitelock have joined in-form All Blacks utility Ben Smith who has also signed through to end of the 2017 season.
