They've hoisted the Webb Ellis Cup a record-breaking three times (1987, 2011, 2015) and boast an impressive win percentage of over 77% in World Cup matches.  They're also the only team to successfully defend the title, achieving back-to-back victories in 2011 and 2015.

Consistently Competitive:  Dominance isn't just about winning trophies. The All Blacks maintain a phenomenal level of performance throughout the rugby calendar.  They hold the record for the most weeks ranked number one in the World Rugby Rankings, showcasing their consistent excellence over a long period.

Ruthless Efficiency: Beyond trophies and rankings, their win rate across all test matches speaks volumes.  Clocking in at a staggering 77%, they consistently dismantle opponents with their innovative tactics and sheer skill. This ruthless efficiency makes them a force to be reckoned with in every match.

The All Blacks Mystique:  Success breeds a unique aura.  The All Blacks are shrouded in a mystique that extends beyond just their playing prowess.  Their pre-match haka, a powerful Maori war dance, is a potent symbol of their unity and determination.  Their iconic black jersey is instantly recognizable and a source of immense pride for New Zealanders.
