The event not only offers the signature 72km solo but a three-leg 72km relay, a 50km race from Turoa Ski Fields to Whakapapa Village and a 24km trail run from Tukino to Whakapapa Village.
"We are grateful for the support of Iwi partners – Ngāti Hikairo, Ngāti Uenuku and Ngāti Rangi, Ruapehu District Council and the Department of Conservation for making this life changing event possible," Cameron said.
Online entries open on July 10 at midday with limited super bird entries.
This year's entries were all sold within 30 minutes. Of the 675 athletes competing, 102 are international runners from 11 countries.
Cameron said he encourages all athletes and their supporters who are planning to attend, to start planning their accommodation as soon as possible as Chateau Tongariro near the Whakapapa Village will be in high demand.
"There are other accommodation options within the Ruapehu region including National Park Village, Ohakune, Raetihi and Taumarunui," said Cameron.
Event festivities will kick off on March 20 with a Powhiri, registration, briefings and an expo.
The first events will begin in the early hours of March 21 with midnight the cut off time for competitors.
The following day a post-event brunch and awards ceremony will be held.
In 2018, records were set for the Ring of Fire 72km Solo by world ranked athlete Lucy Bartholomew from Australia and Sam Clarke from New Zealand.
