The Māori New Year - Puanga for Whanganui people, Matariki for others - will be celebrated with karakia beside the river on July 15.
The occasion starts at 6am at Te Whakaniwha/Putiki Slipway. The karakia will be followed by kōrero and warm refreshments by the slipway.
Organising the Puanga celebrations is a group effort, and Nicole Dryden advises anyone attending should wear warm clothes to beat the predawn chill. People who are not well should follow the Covid-19 protocol and stay at home - they will be able to watch live on Facebook.
Puanga begins when the star Puanga, also known as Rigel, is seen in the morning sky. It has been visible there since last month, Whanganui Regional Museum kaiwhakaako Āwhina Twomey says.
