Many of the nearly 4700 objecting to Taranaki offshore iron-sand exploitation also want to speak at hearings.
A controversial bid to mine an area of seabed off the North Island's west coast has met a backlash, with only a handful of several thousand submissions in support of the plan.
Of just over 4700 submissions received by the Environment Protection Authority (EPA), which is considering Trans-Tasman Resources' application, 99.5 per cent were either fully or partly against the plan.
TTR is seeking a consent to mine 65sq km of exclusive economic zone seabed in the South Taranaki Bight for iron-rich sand particles, using large remote-controlled machines that would travel along the seafloor pumping sand to a processing ship.
The EPA said a wide range of concerns were raised in the submissions, with the majority of issues relating to effects on marine and coastal ecology, erosion and waves, and consequential effects on local communities, recreation, businesses, Maori interests and economy.
