Since 2014, the grant had supported about 50 international productions, he said.
The local film industry employed approximately 14,000 people and generated revenue of $3.3 billion last year.
"Without the grant these international productions would not have located in New Zealand and much of the $3.3 billion would not have been spent here," Bridges said.
Growth in the film sector had a flow-on effect to the tourism and tech sectors, he said.
Artificial intelligence and robotics devised for film productions were being adapted into healthcare and other areas.
On the tourism side, about 18 per cent of visitors to New Zealand said they had travelled here because of Peter Jackson's Hobbit Trilogy.
Barry said the domestic screen grant had supported 23 productions since it was introduced in 2014, including the Taika Waititi hit Hunt for the Wilderpeople.
"The international and domestic screen grants are working hand in hand," she said.
"The successful marketing of New Zealand as an international screen production destination is leading to increased production activity and improved business confidence within the domestic industry."
