The film industry is pleading with the Department of Conservation for lenience over the future use of Mt Aspiring National Park.
Submissions are currently being taken on a draft plan for management of the park's 355,543 hectares over the next decade.
But Film Otago Southland is concerned the plan is greatly restrictive for the industry.
Executive manager Kevin Jennings says he is not seeking completely unrestricted access and is happy to compromise with the department.
Filming occurs in the park once a month, on average, and Mr Jennings says intention books could be used to ensure movie crews do not get in the way of trampers.
However, the department says it is being more than fair to the film industry.
