The Maori, the indigenous people of Aotearoa (New Zealand), have a very rich oral tradition that actually dates back to the time when their ancestors first arrived at the shores of the islands!
These traditions, however, have greatly been influenced by Europeans settlers, especially by missionaries, who tried to destroy the Maori by banning everything Maori: traditional clothing, traditional musical instruments, songs, religious beliefs, even the Maori language itself, everything was banned and violations were punished severely.
No one can say how much knowledge was destroyed during these times.
Kotahi tonue tama
Te tiaki whenua,
Ko te kuranui,
Te manu a Rua-kapanga,
Itahuna e to tupuna, e Tamatea
Ki te ahi tawhito,
Ki te ahi tupua,
Ki te ahi na Mahuika.
Na Maui i whakaputa ki te ao
Ka mate i whare huki o Repo-roa,
Ka rere te momo, e tama e!“
This is the end part of a large Maori poem that can be dated back to the 14th century, around the time when the first Maori settlers arrived at the shores of Aotearoa (New Zealand).
The poem mentions the kuranui, the bird of Rua-kapanga, which is said to have been the first person to have spotted the bird; te kuranui might be translated as ‘the large red one’, ‘the large precious one’ or maybe as ‘the most precious one’.
Furthermore it also informs us about the fate of these kuranui(s): “… destroyed by your ancestor, Tamatea, with underground and supernatural fire, the fire of Mahuika (a fire goddess), brought to this world by Maui; they were driven into the swamps and perished …”
