The New Zealand national men's rugby union team, officially nicknamed the All Blacks, represents New Zealand in men's rugby union, which is regarded as the country's national sport. The All Blacks are three time winners, and current holders of the Rugby World Cup, having won the inaugural competition in 1987, then won consecutive titles in 2011 and 2015, and are the 2015 World Rugby Team of the Year. They have won over 76% of their test matches and are the leading test match points scorers of all time. Their win ratio puts them amongst the most successful teams of any sport in history. They are the only international side with a winning record against every country they have played, and since their international debut in 1903 only five nations have defeated New Zealand in test matches. Since the introduction of the World Rugby Rankings in October 2003, New Zealand has held the number one ranking longer than all other teams combined. The All Blacks are also the first team to set their hands on the Webb Ellis Cup, the first team to win back to back Rugby World Cups, and the first team to win the cup on three separate occasions.
