The South Island iwi wanting to invest in a controversial Hawke's Bay dam says it's up to the Environmental Protection Authority to deal with local iwi concerns.
Ngai Tahu has been named as a potential investor in the Ruataniwha Water Storage Scheme, in the rohe (territory) of Ngati Kahungunu, which is opposed to the project.
Ngai Tahu says the dam would be a good fit for its business because it is familiar with irrigation and water management in Te Waipounamu.
The South Island tribe says it is in talks with Ngati Kahungunu about its investment plans.
The resource consent applications are currently before a Board of Inquiry with the Environmental Protection Authority.
Ngai Tahu Holdings Corporation chief executive Mike Sang says the inquiry should provide an opportunity for mana whenua to seek further assurance about the scheme.
