Matariki is the Māori name for the cluster of stars also known as the Pleiades. It rises in mid-winter and for many Māori, it heralds the start of a new year.
Matariki literally means the "eyes of god" (mata ariki) or "little eyes" (mata riki).
According to myth, when Ranginui, the sky father, and Papatūānuku, the earth mother, were separated by their children, the god of the winds, Tāwhirimātea, became so angry that he tore out his eyes and threw them into the heavens.
Matariki, or Māori New Year celebrations were once popular, but stopped in the 1940s.
In 2000, they were revived. Only a few people took part at first, but in just a few years thousands were honouring the "New Zealand Thanksgiving".
