Should Matariki be a public holiday?

Should Matariki be a public holiday? I think Matariki should be a holiday. New Zealand should have it as a holiday because it is a very important part/day for Maori. It includes their culture and they should get to celebrate the story behind it. Everyone should get to celebrate their own traditions equally. That is why I think it is fair that Matariki should be a public holiday in New Zealand.
