However, private investment was increasingly hard to get. Before 2008, it had paid an average of 20 to 25 per cent of a film's budget. That dropped to 7 per cent in 2011 and was 12 per cent this year.
The global recession had meant fewer opportunities to raise international backing, fewer film distribution companies and more competition.
"It is harder than ever to finance the production of films and there are fewer companies willing and able to buy the films that do get made."
The statement also expressed anxiety about the Government's review of the screen sector, due this month, saying it "could have a dramatic impact on our funding and expenditure".
The Government is considering whether to continue the Screen Productions Incentive Fund, set up under Labour in 2008 to fund some television programmes and films with a budget of more than $2.5 million.
Grants under the scheme can cover up to 40 per cent of the total cost and the commission can top that up by co-investing in the film itself.
That was due to end next year. Last year about $10.5 million was injected into productions in grants and in co-investment with the Film Commission.
If that scheme were discontinued, the commission's large feature-film spending would drop from $12.9 million to $8 million by 2013-14. Spending on short films and initiatives such as training of directors was also expected to be cut as reserves ran out.
Last month, the Herald revealed that Film Commission chief executive Graeme Mason had spent more than any other public sector chief on travel in the previous 18 months - $113,657 - attending overseas film festivals and promoting New Zealand-made films.
