Woodcock made his international debut for New Zealand on 23 November 2002 when he started against Wales at the Millennium Stadium in Cardiff. Woodcock was one of six debutants that day and started alongside Blues teammates
Keven Mealamu and
Daniel Braid, the former of whom would go on to become a long-serving front-row partner to Woodcock. Woodcock played the full 80 minutes, something rare for a prop and the All Blacks beat Wales 43–17. Woodcock did not play for the All Blacks again until 2004, a year when he started three times. Woodcock became a regular starter for New Zealand in 2005, starting in all three tests against the touring
British and Irish Lions team, with the All Blacks failing to lose in all of those tests. Woodcock started in 10 of his 11 international appearances in 2005, and made 10 appearances for the All Blacks in 2006. He was the first All Black prop to score a test try against Australia in 20 years, when he scored the first try of his international career on 30 June 2007 against Australia in a 15–20 loss and another try against Australia the following week, when the All Blacks won 26–12. After his performances through the year, Woodcock was selected for the
2007 Rugby World Cup. Woodcock made started in four of his three appearances in the competition, the most notable being when he played the full 80 minutes of New Zealand's shock 18–20 loss to France in the quarter-final of the World Cup, eliminating them for the competition. Woodcock was retained in the All Blacks in 2008 and on 2 August 2008, he became the first All Black prop to score two tries in a match (a rare feat for a prop against any side) against Australia in over 50 years. He had a heavy workload for the All Blacks in 2008, playing 12 tests for them that year. Woodcock celebrated his 50th test to kick off his 2009 international rugby season, but it was unfortunately spoiled by losing 22–27 on the occasion, against France in Dunedin. He scored New Zealand's only try in the
2011 Rugby World Cup final against
France, becoming the first
All Black prop to score a try in a
Rugby World Cup final, and only the second prop ever to do so. He received his 100th cap for the All Blacks in a test match in Wellington against Australia on 24 August 2013. Woodcock was not subbed off, with replacement prop
Wyatt Crockett instead replacing
Sam Whitelock in the 27–15 win over Australia. Woodcock was named in the 31-man squad for the
2015 Rugby World Cup, where he scored a try in a 47–9 victory against
Tonga in the final pool match of the competition on 9 October. His 118 test-match career in rugby union unfortunately ended in the same match, when he was injured and replaced by Wyatt Crockett in the 43rd minute. Joe Moody was subsequently flown over to England from New Zealand, in order to replace Woodcock, who remained in the country and collected his winners' medal following New Zealand's 34–17 victory in the final against Australia's Wallabies. In the
2016 New Year Honours, Woodcock was appointed a
Member of the New Zealand Order of Merit for services to rugby.
