Harawira said the man's death at this time of the year was particularly sad.
"Christmas is all about celebrating with family and friends, and now this man's whānau will be spending this time grieving for him rather than sharing the festivities with him. They will be in our thoughts as they face this sad time."
The decision to implement a rahui was made in partnership with Te Tapatoru a Toi chairman, Te Kei Merito, he said.
Te Tapatoru a Toi was the joint management committee that was established with representation from Ngāti Awa, the Crown and the community to take care of Moutohora, Ohope Scenic Reserve and Tauwhare Pā.
