The first rising of the Pleiades and of Rigel (Puanga in Māori) occurs just prior to sunrise in late May or early June, and this indicates that the old year has ended and the new year has begun. The actual time for celebrating Matariki varies, depending on the iwi (tribe or clan). Some iwi celebrate it immediately. Others wait until the rising of the next full moon, or alternatively the dawn of the next new moon. It has become common practice for various private and public institutions to celebrate Matariki over the period of a week or month anywhere from early June to late July. Other iwi used the rising of Rigel in a similar way.
In traditional times, Matariki was a season to celebrate and to prepare the ground for the coming year. Offerings of the produce of the land were made to the gods, including Rongo, god of potato. This time of the year was also a good time to instruct young people in the lore of the land and the forest. In addition, certain birds and fish were especially easy to harvest at this time.
National holiday proposals
From time to time, there have been proposals to make Matariki an official holiday in New Zealand. In 2001, The Māori Language Commission "began to reclaim Matariki, or Aotearoa Pacific New Year, as an important focus for Māori language regeneration. The commission is spearheading a campaign to elevate Matariki into an iconic national event as part of a nationwide Māori language information programme, "Kōrero Māori", and intends to develop relationships and partnerships in order to co-ordinate and share activities with other stakeholders while complementing existing events".
In June 2009 Maori Party MP Rahui Katene was unsuccessful in having her member's bill 'Te Ra o Matariki Bill/Matariki Day Bill' drawn from the ballot. The draft legislation would have fixed the date of a public holiday using the New Moon in June.
