"It is a fun and colourful festival that involves a large - over 7 metre high - decorated chariot [Rath] which is pulled by ropes by the public through the main streets of town accompanied by music and dance.
"There is much spiritual and cultural significance to the festival."
The festival will conclude with a free vegetarian lunch in Cafler Park, although the public are invited to help pull the chariot through the city, if they wish.
Ratha means chariot and yatra means journey.
The festival refers to the annual journey of the divinity in the form of idols to their aunt's house. "Aunt" here refers to the feminine creative aspect of divinity.
The festival is also responsible for a common word used around the world. A figurative reference to a chariot containing Lord Jagannath has resulted in the English word juggernaut to refer to an unstoppable force.
The Krishna community will then take the chariot on tour starting from Cape Reinga on January 22 and hauling it for 10 days down to Karikari Peninsula, a trip of about 150km.
The walk is called Walking for a Change to encourage people to make some necessary changes in their lives and get back to a more simple, slower, and saner way of life, Mr Wilcox said.
