However, the group was granted leave for a third challenge, being heard in the Court of Appeal this week. That challenge is again seeking the court to overturn the consent granted by the council to Creswell.
A local community group, Sustainable Otakiri, which was established for the purpose of challenging the water bottling plans, has also joined Te Rūnanga in challenging the consent in the court.
The groups' case rests on a variety of claims, including that the authority issuing the consent didn't adequately consider the environmental effect of plastic bottles.
The groups also claim that the Environment Court didn't pay enough consideration to the environmental effects of the activity, and should have sought further evidence.
The significance of wai to Māori has also been a key aspect of the previous challenges.
In her opening statement, Counsel acting for Te Rūnanga Ella-Rose Kini told the court that the basis of the claim rested on the belief of "he taonga tuku iho te wai", a loose translation of "water is an inherited treasure".
However, the company at the centre of the bottling plans has previously said it has attempted to engage with the iwi around its plans.
That included offering Ngāti Awa a shared-governance role in the operation of the plant so they can undertake their cultural kaitiaki, or guardianship responsibilities.
The company also noted both China and New Zealand's commitment to end single-use plastic by 2025. The plant is not expected to become operational until 2027.
The case is expected to wrap up by the end of the week.
