Instead of referring to it as a single custom, it's more appropriate to talk about specific Māori customs such as:
* Tīkanga: This is the term for Māori customary law, values, and protocols.
* Haka: This is a traditional war dance, but also used for performance and ceremony.
* Karakia: This refers to Māori prayers and incantations.
* Tangihanga: This is the Māori funeral process and mourning period.
* Marae: This is a traditional meeting place and gathering space.
* Taonga: This refers to Māori treasures and cultural objects.
It's important to be respectful of the nuances and diversity within Māori culture. If you are interested in learning more about specific Māori customs, it's best to consult resources from Māori experts and communities.
