The Gallaher Shield is awarded to the winner of the Auckland Rugby Union senior premier competition, and was first awarded in 1922. The shield is named in honour of Dave Gallaher, an early stalwart of Ponsonby, Auckland and New Zealand rugby. Ponsonby are by far the most successful club in Auckland history, with 37 shield wins and 48 championships in total.

As of the 2025 season.
