In 2011, New Zealand was crowned Rugby World Cup champion. Two years later in 2013, the team emerged undefeated all year, a perfect record, the first for a national professional team. And on Nov. 1, 2014, New Zealand’s All Blacks played against USA’s Eagles before a crowd of 60,000 in what was described as the biggest rugby event on American soil ever, cruising by the U.S. team with an impressive 74-6 victory. From their triumphant stats, the kiwis are playing in a league all their own. But how has a country with a population just one quarter of London’s been able to dominate international rugby in a way not seen in almost any other sport? Photographer Nacho Hernandez, a former rugby player himself, spent four months in New Zealand to find out. His photographs, taken over a year, explore the culture and the passion of its fans young and old.

Pride in their country’s legacy of rugby reverberates among New Zealand fans, where even one loss is met with the depression of 10. Historically, the All Blacks have won more than 75 percent of the matches they have played since 1903, and they have an overwhelming winning record, one on one, against any other team in the world. In the history of rugby, only five nations have ever beaten New Zealand. They have not lost a game at Eden Park, the country’s main rugby field in Auckland, since 1994. New Zealand as a country has sometimes been described as an experiment to transplant an idyllic British society in the middle of the South Pacific. With regard to rugby, at least, the success was complete. Although invented in England, rugby fits New Zealand like a glove. The first New Zealanders who played it not only had inherited the love and penchant for sports from England, but they were also very tough and rugged, settlers and farmers used to hardship. The sport suited them.

Rugby games in New Zealand are often punctuated by a variety of rituals that have come to help define the sport. Mooning? Check. Falling in that vein of taunting is the infamous Haka. “Few things represent New Zealand rugby as well as the Haka. This Maori dance has been performed by the All Blacks since their first international games, but in the past it was a half-hearted affair, more cute than threatening. A Maori player from Rotorua, Wayne ‘Buck’ Shelford (All Black n. 860), is credited with having transformed the All Blacks’ Haka in the late 1980s,” Hernandez explains to In Sight.
