After winning a third title with the Crusaders in 2000, he was again selected for the All Blacks; getting a start against Tonga, and in that years Tri-Nations. After returning from All Blacks duty, he played for Canterbury and contributed to a Ranfurly Shield win over Waitako. Canterbury then reached the NPC final, giving Hammett the opportunity to be part of a Super 12, Ranfurly Shield, and NPC winning team, all in the same year. Wellington won the NPC final however, and the opportunity was lost. Hammett was then selected for the end-of-year All Blacks tour, and played against France and Italy (both as a substitute).
