"We've got a long coastline and it's a big part of our district."
Fishing people, and he is one of them, were worried mining would affect fish and other marine life.
"It's a particularly good fishing spot off Patea and Ohawe."
Coastal erosion and water clarity were other concerns.
But if mining can happen without environmental damage, a clear majority of councillors want to make sure South Taranaki benefits. It wants the mining administration office to be based in Hawera, and the hearings about the marine consent to happen there too.
And it wants the ships working offshore to be serviced by helicopters based at Hawera.
"That's the key to it. Where the helicopter flies from is where people are probably going to live," Mr Dunlop said.
It would also like financial grants and assistance for local communities.
Taranaki Regional Council has also made a submission to the marine consent application. A spokesman said the submission had not yet been endorsed by the policy and planning committee, and would be released in late January.
Horizons Regional Council has submitted that environmental effects must be avoided, especially sediment plumes that could reach south of the Waitotara River where the Horizons region begins.
