King Tuheitia will tonight host 150 dinner guests to mark the beginning of Matariki, and start a new tradition.
Matariki is the name given to the stars in the Pleiades cluster and the traditional Maori festive season of celebration and preparations for te tau hou, the new year ahead.
Tonight will be the first time King Tuheitia will host a formal Matariki dinner at the Waikato-Tainui College for Research and Development, but it will become an annual tradition, said his spokesman Rahui Papa.
Mr Papa said the event would be "very special and very unique" in its celebration of Kingitanga and the new year, topics important to the King.
"The beginning of the new Maori year is a huge part of it and it commemorates his official royal crest," he said.
