Matariki is the Māori name for the Pleiades star cluster. Before sunrise during New Zealand’s winter, the cluster is visible as a faint sparkle of tiny dots when you look towards the northeast horizon. It rises during Pipiri (June/July) and marks the beginning of the Māori new year. Generally, the Māori acknowledge nine main stars in the group. 

The word is an abbreviation of Ngā Mata o te Ariki (Eyes of God) in reference to Tāwhirimātea, the god of the wind and weather. In the story of creation, Tāne Mahuta (god of the forest) separated his parents Ranginui and Papatūānuku, and his brother Tāwhirimātea got upset and tore out his eyes, crushed them into pieces and thew them into the sky. 

Traditionally, Maori iwi, or communities, would gather together at night during a time of the constellation’s prominence, making use of the period between harvests to celebrate and make offerings for a bountiful future. 

When Matariki disappeared in April/May, it was time to preserve crops for the winter season. When it re-appeared in June/July its appearance was said to predict the success of the season ahead; clear bright stars are a good omen and hazy stars predict a cold, harsh winter. The brightness of each individual star predicts the fortunes of a specific thing that the star represents, such as the wind or food that grows in trees. 

Some iwi recognise this time of year by the appearance of Puanga, also known as Rigel. There are also regions where the setting of Rehua, also known as Antares, is used to identify the change of seasons.
