Waikato had qualified highest during the regular season, while Wellington qualified fourth. Waikato won their semi-final, where they beat Otago 44–15. Wellington travelled to Auckland where they beat Auckland in their semi-final. Waikato hosted the final after qualifying higher than Wellington, who had to travel back from Auckland for the match.
Waikato claimed the Air New Zealand Cup with a four tries to three 37–31 win over Wellington in ideal conditions in Hamilton. The final margin suggested a closer match than was actually the case. Waikato dominated for long periods of the game. When Waikato's replacement halfback Brendon Leonard went over from a scrum just out from the Wellington line after 71 minutes, Waikato Stadium's full house of 25,000 rejoiced. They knew they had their first national title since 1992. There was a momentary concern for fans when Wellington wing Ma'a Nonu scored his second try, two minutes later, and when captain Tana Umaga scored with less than a minute remaining but Wellington was still six points behind and the damage had been done. Flanker Marty Holah was outstanding in the rucks and mauls for Waikato while halfback Byron Kelleher had his most competitive appearance in recent weeks. Locks Keith Robinson and Jono Gibbes kept the pressure on the Wellington lineout which was its shoddiest of the year. At crucial lineouts its execution was deficient on too many occasions. David Hill, who is also leaving for the northern hemisphere, kicked 17 points for Waikato. Wellington was forced to battle without its leading prop Neemia Tialata, who did not start, and then it lost Joe McDonnell halfway through the first half. That brought Anthony Perenise on to the tighthead side of the scrum for only his third first-class appearance. It was a significant loss, more in terms of the leadership Tialata brought to the forward effort over the past few weeks. The match, in front of a capacity crowd of just over 25,000, started at breakneck speed with both teams throwing passes with gay abandon and it was Wellington that had the first success with a seventh-minute penalty goal to first five-eighthsJimmy Gopperth. Two Waikato errors, an accidental offside from a lineout move, and knock-ons by Kelleher and wing Sitiveni Sivivatucost it 70 metres in ground. Wellington then made its own mistake with a lineout throw taken by Holah and it stormed back into the Wellington half. And when captain and flanker Steven Bates won a clean lineout take, the ball was spun and while second five-eighths David Hill took a big hit, his transfer to wing Sosene Anesi was inch perfect and he burst into a gap and when tackled he found centre Richard Kahui on hand to race in for the opening try. Hill got up from his tackle and landed the conversion. Gopperth landed his second penalty goal after 19 minutes to get Wellington back to within one point at 6–7. Waikato used its lineout to good effect to set up its second try, scored after 27 minutes by Kelleher. Several drives were made at the line with lock Keith Robinson hit in a big tackle by flanker Jerry Collins. However, Waikato controlled the ball provided under the posts by the halfback. Wellington then fouled its own chance with indecisive ball from a scrum. Gopperth was forced to tidy a poor pass from halfback Piri Weepu and in the tackle by Holah the ball was lost with Waikato clearing downfield. Wellington regained the ball from a turnover, the ball was moved left, then right, and No.8 Rodney So'oialo sold a big dummy to Kahui. He sped through the gap and after drawing the defence found the flying Nonu in support and he scored beneath the posts. Gopperth's conversion made the score 13–14. A 36th-minute penalty goal to Hill gave Waikato its lead. The second half had a controversial start when from a Wellington scrum about 10m out from its line Holah kicked the ball through and as Weepu waited for the ball to cross the line, he found Kelleher sliding through to win the try. Hill landed a splendid conversion to take Waikato out to 24–13. Gopperth and Hill exchanged penalty goals in the ninth and 13th minutes.
