More than 80 submissions from as far afield as Australia and the United Kingdom have been received on a proposal to establish a float-plane operation on Lake Wakatipu.
The submission deadline has been extended until Thursday.
Rachel Beer, of Lakes Environmental, said 72 submissions had been received by Thursday afternoon. Of those, 54 were in opposition and 17 were in support, with one submitter conditionally opposed.
About another dozen submissions had arrived on Friday and while there had not been time to enter them, they were all in opposition, Ms Beer said.
Brent Collins (38), originally from Blenheim - a commercial pilot living in South Africa - is seeking land use consent to establish the new float-plane tourism venture on Lake Wakatipu, a proposal first aired two years ago.
It would primarily take people on sightseeing trips from Queenstown to Glenorchy, however, operations would also include charter trips to Lakes Wanaka and Hawea.
The application proposed to base the operation at a floating pontoon on the Queenstown Gardens side of Queenstown Bay, using a water-taxi system to shuttle passengers to and from the plane.
Take-off and landing areas would be located in the open waters of Lake Wakatipu, with a reserve site located at Frankton Arm.
Mr Collins intended to use a de Havilland Beaver (DHC-2) with a three-bladed prop and/or a Cessna 206 (non-turbo) for the venture, which would operate up to 16 flights a day in winter months and up to 22 per day during summer months.
Lakes Environmental secretary Rachel Beer said the submission period was extended to enable ample time to extract addresses from the Queenstown Lakes District Council's rate database and serve it to those deemed by the planner as "potentially affected parties".
"Those parties are required to have the documents served to them for a full 20 working days."
