The bishop's spokesman, the Reverend Ngira Simmonds, said the three Te Arawa hapu directly affected by the proposed road - Ngati Hurunga Te Rangi, Ngati Te Roro o Te Rangi and Ngati Uenukukopako - had already given land to the council for roading and city development when Rotorua was established and shouldn't be expected to hand over more.
"It's the God-given right of these hapu to occupy their whenua [land] and to exercise kaitiakitanga [guardianship] over that land.
"We also believe this proposal is contrary to Te Tiriti o Waitangi [Treaty of Waitangi] - because the treaty guarantees Maori the right to exercise rangatiratanga [sovereignty] over their lands."
Since the NZTA confirmed the go-ahead for the road in early April there has been growing public opposition.
About a month ago a Facebook page was set up, called Resistance Against Te Arawa Land Confiscation, as well as an online petition, by concerned Owhata residents.
