Matariki, the start of the Māori New Year, is signalled by the appearance of seven stars low on the north-eastern horizon at dawn. Also known as Pleiades, the stars arrive any time from late May to mid June. This year the stars arrived on 18 June. Different tribes celebrated Matariki at different times. In the 21st century, the New Year starts with the first new moon following the rising of Matariki.
