In June 2003, Carter made his All Blacks debut at age 21 in Hamilton, New Zealand, scoring 20 points against Wales. He was then capped against France in Christchurch, which the All Blacks won 31–23. He was also a substitute in a match against Australia (the "Wallabies") in Sydney, which the All Blacks won 50–21. Carter was then included in New Zealand's 2003 Rugby World Cup squad, where he first gained serious international attention. Carter spent much of the latter stages of the tournament on the bench leaving New Zealand without a specialist goal-kicker. However, he did play in the games against Italy in Melbourne, which the All Blacks won 70–7, and the wins over Canada and Tonga. Although he has been an All Black since 2003 he only secured a permanent position as the first five-eighth in the team during the 2004 tour to the United Kingdom and France displacing Carlos Spencer. He had been playing as a second five-eighths up until the end of the 2004 Tri-Nations.
