"We appreciate the community's patience and support while we work to ensure kauri are safe."
Rawhiti 3B2 Trust spokesman Andre Witehera said the two are working collaboratively to manage this issue.
"3B2 Ahu Whenua Trust supports all efforts in safeguarding the mauri of this taonga, and we are working in partnership with the conservation agencies to have a mitigation plan in place to prevent the spread of this devastating disease," Witehera said.
Kauri dieback is a microscopic fungus-like pathogen that spreads through the movement of contaminated soil and water. People walking through contaminated soil or water can spread the disease on their footwear.
