Haka is a traditional Maori performing art, typically performed in unison by a kapa haka group. It is characterized by vigorous, rhythmic movements of the entire body, stamping of the feet, and stylized gestures. A central feature is the chanted vocal accompaniment, delivered with powerful rhythm and intonation.

Fierce facial expressions, including pūkana (bulging eyes) and whetero (protruding tongues), are used to convey emotion and intensity, with the specific intent varying depending on the occasion. The quivering movements of the hands, known as wiripapa, are said to represent the dance of Tane-rore, the personification of shimmering, heat-hazed air, and are considered fundamental to the art form.

There is a wide variety of haka performed by both men and women, each with its own purpose, chant, and choreography. The specific words and actions of each haka often narrate a particular story, genealogy, or historical event. While some are highly traditional, featuring only vocals, body percussion, and taonga pūoro (traditional instruments) like Māori flutes and trumpets, others show influence from European-style music in harmony, melody, instrumentation, and lyrical content.
