* Status and Rank: The heru, especially those made from precious materials like bone, ivory, or adorned with feathers and intricate carvings, were indicators of a person's social standing, lineage, and mana (spiritual power or prestige). High-ranking individuals and chiefs often wore elaborate heru to symbolize their importance.
* Spiritual Significance: Hair itself was considered tapu (sacred) in Māori culture, representing a connection to the spiritual realm and ancestral lineage. The heru helped to keep the hair neatly arranged, reflecting respect for this sacred aspect of the body.
* Ornamentation and Beauty: Heru were decorative items that enhanced a person's appearance and added to their overall adornment. The intricate designs and materials used in their construction were a testament to Māori artistry and craftsmanship.
* Practical Use: While ornamental, the heru also served the practical purpose of keeping the hair in place, especially for men who often wore their hair long.
* Gender Differences: While both men and women wore heru, the styles and materials often differed. Men's heru were typically larger and more elaborate, reflecting their roles as warriors and leaders, while women's heru might be more delicate and refined.
