A haka is a traditional ancestral war cry, dance or challenge of the Māori people of New Zealand which the New Zealand national rugby union team, the "All Blacks", and a number of other New Zealand national teams perform before their international matches. Some non-New Zealand sports teams have also adopted the haka.
During 1888–89, the New Zealand Native team toured the Home Nations of the United Kingdom, the first team from a colony to do so. It was originally intended that only Māori players would be selected, but four non-Māori were finally included. As the non-Māori were born in New Zealand, the name "Native" was considered justified. The team performed a haka before the start of their first match on 3 October 1888 against Surrey. They were described as using the words "Ake ake kia kaha" which suggests that the haka was not "Ka Mate". It was intended that before each match they would perform the haka dressed in traditional Māori costume but the costumes were soon discarded.
The "Ka Mate" haka was not well known at this time. In 1900, a newspaper reported New Zealand soldiers in the Boer War chanting "Ka Mate! Ka Mate! Ka ora! Ka ora! Hae-haea! Ha!" The soldiers thought it meant "Kill him! Chop him up! Baste him!"
But during the 1901 Royal Tour, Ngati Kahungunu warriors revived "Ka Mate" when they performed it to welcome the Duke of Cornwall at Rotorua. Newspapers described the full actions of this "ancient ngeri", printing its complete Maori words and an accurate translation. A movie cameraman recorded the performance. "Ka Mate" became famous, and was widely performed throughout New Zealand.
Nevertheless, when New Zealand played its first full international test match against Australia in Sydney in August 1903, the New Zealanders' war cry was "Tena Koe Kangaroo." (full details below)
