Majestic Square will be brimming with live music, art, cultural performances and a variety of food as the city celebrates the Māori New Year, Puanga, at the end of this month.
The community event, called Puanga Rising, is to be held at the square between 5.30pm and 8.30pm on Friday, June 24 - the day New Zealand has its first Matariki public holiday.
The event is being organised by Mainstreet Whanganui and Whanganui District Council, with support from the Whanganui Regional Māori Tourism Organisation and the Town Centre Regeneration project.
Mainstreet Whanganui general manager Des Warahi said it would be fantastic to have a whānau-focused event in the heart of the city.
"With this new public holiday, we have an opportunity to create something special in Whanganui that brings people of all ages and backgrounds together to learn about Puanga, enjoy awesome live entertainment and sample delicious kai."
Whanganui Mayor Hamish McDouall said he was excited about the prospect of a new event here, especially one that offered a chance to learn about the region's unique traditions.
