After re-committing to New Zealand Rugby for another four years in 2013, Whitelock and Brodie Retallick became a World-Class locking combination and started together eight times in 2013, with Whitelock playing in 12 of the All Blacks' 14 tests in 2013. Whitelock was only subbed off twice the All Blacks' unbeaten year, in tests against France, Australia and Argentina. He also played his 50th test in the 30–22 win over England on the 2013 end-of-year tour, but this was unfortunately overshadowed by the fact that 2005 and 2012 World Rugby Player of the Year-winning Crusaders teammate Dan Carter had been subbed off in the 25th minute of that match which was Carter's 100th.
