Auckland also accounted for almost 100 per cent of broadcasting revenue, worth $1,403 million last year, the figures showed.
Feature films continued to dominate the film sector's revenue streams, contributing over 50 per cent of all production and post-production revenue, Attewell said.
"The total revenue is largely driven by a few businesses - those with revenues of at least $50 million - but over 91 per cent of all screen businesses earn less than half a million dollars each," he said.
"Many businesses in the screen industry are one-person contractors.
"To put this in context, 15,500 people were employed directly by the screen industry over the year ending March 2013, and they earned $742 million in wages."
The vast majority of screen businesses were engaged in production or post-production work, Attewell saied.
In terms of value added, the screen industry added $1.1 billion to the economy, and almost half a percent of Gross Domestic Product (GDP).
