The Hanan Shield is one of the most prestigious trophies in New Zealand's domestic rugby union competition. First played for in 1946 after being presented by the Mayor of Timaru, A.E.S. Hanan. The Hanan Shield is based on a challenge system played between North Otago, South Canterbury and Mid Canterbury. The holding union must defend the shield in challenge matches, and if a challenger defeats them, they become the new holder of the shield. A rules change at the end of the 2011 season meant that the shield is up for challenge in any meeting between the holders and one of the other two teams.^[1]

• A draw is recorded as a win for the holders

On 6 October 2007, Mid Canterbury won the Shield from North Otago, who had held the shield since 2000, with a 25–22 victory. In a fiercely contested clash in front of a record crowd at Oamaru's Centennial Park, Mid Canterbury played themselves into a Shield winning position. Mid Canterbury made the decisive break thanks to two stunning solo tries to young winger Brenton Connell, then hung on in the final 20 minutes despite losing star midfielder Jack Umaga to a broken jaw. This ended North Otago's Hanan Shield reign of 14 defences over seven years.^[2]

On 9 August 2008 Mid Canterbury made their first Hanan Shield defence when they ran onto the Ashburton Showgrounds to play South Canterbury in the first Hanan Shield match contested under the new experimental law variations (ELVs). It was South Canterbury who put on the early pressure with prop Timaru Tafa crossing in the 6th minute. Mid Canterbury's 19-year-old wing Brenton Connell sliced through a midfield gap on his own 10-metre line, broke a tackle and sprinted away down the left-hand flank to score in the corner. In the 29th minute, loose forward Jon Dampney showed his strength in shrugging off a tackler to score in the corner. Connell made it two for the afternoon when Dampney took a quick throw, which saw the ball spread to the opposite sideline into the hands of Connell who crossed the line and scored. South Canterbury started the second half strong, and scored two tries in the first 10 minutes, to loose forward Eric Smith and Tafa got his second. Mid Canterbury were trailing 19–18 but were not about to give up. A try to second five-eighth Richard Fridd pulled them back into the game, while two more tries were scored by first five-eighth Dan Maw and Dampney who scored his second.
