Max Burgess, speaking for the Pataua Residents and Ratepayers Association's application, said infrastructure in the area had not kept pace with increased demand.
"The proposal will not impact negatively on the environment or the general community's ability to enjoy the area."
The once-sandy bottomed beach had become too muddy to launch boats off it when the tide dropped, and there were also safety issues with cars maneuvering amongst children and other people using the beach in summer, Mr Burgess said.
Among several speakers from Ngati Korora/Te Waiariki iwi and hapu who oppose the plan, Tanya Monroe said Whangarei District Council and Department of Conservation had a poor record of looking after public land at the Pataua river estuary where houses and baches encroached on land gazetted as reserve.
Resident Mike Bell said the reclamation proposal was being promoted under the Residents and Ratepayers Association banner but did not have a community mandate. "Six months of the year it's busy with boat launching. Should we fill in a beach to park cars and trailers?"
He said a more widely acceptable proposal could be developed with the reputed $170,000 price tag.
