Kapa haka is the term for Māori action songs and the groups who perform them. The phrase translates to 'group' (kapa) 'dance' (haka). Kapa haka is an important avenue for Māori people to express and showcase their heritage and cultural Polynesian identity through song and dance. Modern kapa haka traces back to pre-European times where it developed from traditional forms of Māori performing art; haka, mau rākau (weaponry), poi (ball attached to rope or string) and mōteatea (traditional Māori songs). There is a regular national kapa haka competition currently called Te Matatini that has been running since 1972. A kapa haka performance involves choral singing, dance and movements associated with the hand-to-hand combat practised by Māori in mainly precolonial times, presented in a synchronisation of action, timing, posture, footwork and sound. The genre evolved out of a combination of European and Māori musical principles. The current form relates to kapa haka concert groups that first appeared in the 1860s especially in Rotorua to cater to tourists. The work of a kapa haka consists of the group performance of a suite of songs and dances spanning several types of Māori music and dance, strung together into a coherent whole. Music and dance types that normally appear are waiata tira (warm-up song), whakaeke (entrance song), waiata-ā-ringa (action song), haka (challenge), pou or mōteatea (old-style singing), poi (coordinated swinging of balls attached to cords), and whakawātea (closing song). They may also include tītī tōrea (synchronised manipulation of thin sticks). In a full performance, which can last up to 40 minutes, each music or dance type may appear more than once. Music for kapa haka is primarily vocal. All song types, with the notable exceptions of mōteatea and haka, are structured around European-style harmony, frequently with guitar accompaniment and acoustics. Spurts of haka-style declamation are woven into the songs, as are dance movements, facial expressions and other bodily and aural signals unique to Māori.
