Why do people use hakas?

People use hakas for various reasons, primarily as a traditional ceremonial dance of the Māori culture in New Zealand. It is performed to express a range of emotions, including celebration, grief, or to challenge opponents in a show of strength and unity. In contemporary contexts, hakas are often performed at sports events, especially by New Zealand's national Rugby team, the All Blacks, to inspire pride and solidarity among players and fans. Additionally, hakas serve to preserve Māori culture and heritage, fostering a sense of identity and community.
