A local iwi representative says accessing the Pink & White Terraces would be "tremendous".
New research has sparked new hope of returning the terraces to public view - 131 years on from the Mt Tarawera eruption.
Researchers Rex Bunn and Dr Sascha Nolden have acknowledged the help of Te Tuhourangi Tribal Authority trustee Rangitihi Pene. Mr Bunn initially approached Te Tuhourangi Tribal Authority in 2014 while researching the terraces and Mr Pene said they had been in communication since then.
For Mr Pene there is a direct link as his great-grandmother lived in Te Wairoa before resettling to Whakarewarewa.
"They were our introduction to the world of tourism, not just the guiding but the hotel industry," he said.
