"Securing safer and improved community-owned air and water access, improving rundown roadways and installing water systems are all the kinds of projects the Motiti Project Fund could enable through granting this consent."
Ms Barry-Piceno said the island's environment was at risk because of its unprotected waterways, lack of community wastewater or freshwater systems and lack of public infrastructure.
Long drops were still in place on the island and fed into the water.
In making their decision to support the applicant, Ms Barry-Piceno said the group's tangata whenua members considered it best to follow their traditions of relying on their elders, known collectively as Korowai Kahui o Nga Pakeke o Te Patuwai.
Group chairman Peter Grant said the decision to support the application was not made lightly and was not based solely on the financial compensation being offered.
"If the consent is granted and the project fund is established, we will finally be able to gain closure with the conflicts between our people."
At the end of Mr Grant's presentation Jim Takotohiwi, who owns land on Motiti but has not been a resident on the island for many years, stood up to speak.
Mr Takotohiwi said he was aghast to see his name registered as a member of Motiti Environmental Management Group and in support of the wreck staying.
He had sat in on the hearings since the beginning and had slowly been forming his own view, which now leaned towards full removal.
