Queenstown Lakes Mayor Vanessa van Uden said the council, which provided funding and office space for the film office, was leading the review.
The office - which is independently of the council - was established in 2004 to attract film, TV and commercial projects to the South.
According to Statistics New Zealand, film activity brings $20 million a year into the local economy.
Ms van Uden said the council recognised the ''significant economic activity'' and the benefits it brought to the district and wider Southern region.
''After 10 years we want to check the [Otago Southland] Film Office has the right structure and sufficient resources to support this significant activity ''.
A discussion document had been released with feedback invited from the film industry, stakeholders and community.
Key questions included whether the structure was right and how the Otago Southland model compared with others; if a different structure should be considered, for example, should the office sit within the council, or a council-aligned body; and what councils or funders should expect to receive in return for the investment.
It also asked if consideration should be given to a ''local film office, i.e. Queenstown only''.
Feedback had been collected from three Otago Southland Film board members, and industry representatives, including the New Zealand Film Commission's chief executive.
That exercise found a film office based in Queenstown was ''essential'' and the Film Office should be independent of both the council and tourism promotion bodies.
''The overwhelming message from the industry and key stakeholders is that the office delivers an essential service,'' the document said.
''Collectively the feedback points to the need to invest in the resource ... likewise there is strong agreement that additional funding ... should be sought to meet additional investment in the office.''
Part of the review would be to look at the resourcing for the office, regarded by the New Zealand Film Commission as one of the three main regional film offices, together with Auckland and Wellington.
However, by comparison it was understaffed. Its sole employee, Kevin Jennings, was contracted to work 32 hours a week, but the workload consistently required him to work more than 40 hours a week to meet industry expectations.
''The industry requirement is for a fulltime level of service. Given funding constraints, the board has been of the view it did not have the ability to formally offer Mr Jennings increased hours or pay.
''Despite challenges, Mr Jennings is considered by the industry and key stakeholders to have performed strongly in terms of meeting industry and stakeholder expectations.''
Online feedback on the review closes on January 22.
