* Ceremonial Use: Māori masks were primarily used in ceremonial contexts and religious rituals, often associated with specific events, deities, or ancestors. They weren't everyday objects.
* Specific Roles: Masks played distinct roles in these rituals, embodying spirits, ancestors, or powerful beings. Their use was highly specific to the occasion and the community.
* Carving Tradition: Māori masks were carved by skilled artisans and imbued with significant cultural meaning. They were not simply decorative items but powerful representations of their beliefs.
Therefore, instead of talking about when they were worn, it's more accurate to say that Māori masks were used in ceremonies and rituals throughout their history.
To further clarify, it's important to avoid generalizations. Specific types of masks might have had specific uses and timings. You might find information on the use of particular masks associated with certain rituals or tribal groups.
