The New Zealand national rugby union team, commonly called the All Blacks, represent New Zealand in men's rugby union, which is regarded as the country's national sport. The side has won the last two Rugby World Cups, in 2011 and 2015, as well as the inaugural tournament in 1987. They have a 77% winning record in test match rugby, and are the only international side with a winning record against every opponent. Since their international debut in 1903, they have lost to only six of the 19 nations they have played in test matches. Since the introduction of the World Rugby Rankings in 2003, New Zealand has held the number one ranking longer than all other teams combined. The All Blacks are statistically the best side to have played the game, and jointly hold the record for the most consecutive test match wins for a tier one ranked nation.
New Zealand competes with Argentina, Australia and South Africa in The Rugby Championship. The All Blacks have won the trophy fourteen times in the competition's twenty-one-year history. New Zealand have achieved a Grand Slam (defeating England, Wales, Scotland, and Ireland in one tour) four times – 1978, 2005, 2008 and 2010.
The All Blacks have been named the World Rugby Team of the Year ten times since the award was created in 2001, and an All Black has won the World Rugby Player of the Year award nine times over the same period. Fifteen former All Blacks have been inducted into the International Rugby Hall of Fame. All Black coaches have won World Rugby Coach of the Year nine times since the award's 2001 launch.
The team's first match was in 1884, and their first international test match was in 1903 against Australia in Sydney. The following year they hosted their first ever home test, a match against a British Isles side in Wellington. This was followed by a 34-game (including 5 tests) tour of Europe and North America in 1905, where the team suffered only one defeat – their first ever test loss, against Wales.
New Zealand's early uniforms consisted of a black jersey with a silver fern and white knickerbockers. By the 1905 tour, they were wearing all black, except for the silver fern, and their name "All Blacks" dates from this time.
The team perform a haka, a Māori challenge or posture dance, before each match. The haka performed has traditionally been Te Rauparaha's Ka Mate, although since 2005 Kapa o Pango is often performed. Wikipedia
