Film Otago Southland executive manager Kevin Jennings said film, television and commercial production tended to ''go into the doldrums'' between the traditional peak times of summer and winter.
However, TV commercial shoots had extended through April, providing the industry with a steady stream of activity since last winter.
Most were international ad productions, selling ''everything from air conditioners to beer to pharmaceuticals - and a lot of car ads''.
''We've seen a real increase in the Korean market, and a steady build on Chinese jobs as well.''
It comes on top of two feature film productions that have wrapped up in the past fortnight.
Walt Disney movie Pete's Dragon was shot throughout April in Tapanui, while independent film The Inland Road finished a five-week shoot based in Arrowtown last Sunday.
Mr Jennings said one of Film Otago Southland's goals was to minimise the peaks and troughs in the industry in the same way the tourism industry tried to do.
Companies providing supporting infrastructure for film, television and commercial productions tended to be small, independent operators who knew they had to ''make hay while the sun shines to get through the lulls''.
''So when you get this tail-end that is still going strong, it's a real boost.''
The region traded heavily on being the opposite season to the northern hemisphere, and could offer a wide diversity of landscapes within two hours' drive of Queenstown.
''If you watch ads you'll see they often go from city to barren to lush - they tell the story through the background.
''We'll have shoots that might be in Invercargill, down at the beach or the Catlins, Fiordland, arid Central Otago and then Glenorchy - all in one ad.''
