It's called Martha Ricky, a celebration of the Maori New Year marked by the appearance of a star cluster known as the Pleiades.

Prime Minister Jacinda Arden, who had pledged to establish the public holiday during her re election campaign, made the announcement on Thursday.

This is not just about a public holiday.

It is a teaching moment, a chance to learn about something that is uniquely Marty, a chance to learn around navigational history and we will begin doing that from the year 2022.

And I can share for the first time today that the first celebration of metallic E after much advice from our advisory committee will be on the 24th off June 2022.

Our turn made her announcement at White Tongi, where over 150 years ago a treaty was signed between Maori chiefs and the British crown.

But that treaty has since been broken as the Maori lost much of their land under British colonization.

Thousands of Maori, who currently account for about 15% of New Zealand's population pro tested our turns government in 2019, saying they hadn't done enough to acknowledge their civil and social rights.

On Wednesday, New Zealand's government also proposed a national syllabus on Maori history.

The course will cover the Maoris arrival to New Zealand, the country's immigration and colonization, and the Treaty of White Tongi.
