New Zealand taxpayers put up an "extreme" amount of money to get the Hobbit films made here - and the real winner was Warner Bros, the Green Party says.
The Government has defended the spending of close to $200 million as having wider benefits - including more than one in ten visitors citing the movies as a reason they became interested in visiting.
The latest statements for Warner Bros Entertainment's New Zealand subsidiary, 3 Foot 7, show the firm received a large budget screen production grant of $38.3 million in the 12 months to March 31 this year.
That adds to the $54.6 million it received in the 2014 year, $31.3 million in 2013, $46.9 million in 2012 and $20.2 million in 2011.
Across the five years, production costs amounted to around $1.1 billion, meaning the Warner Bros unit has claimed about 17 per cent of total costs under the grant.
Green Party finance spokeswoman Julie Anne Genter said the level of taxpayer money stumped up was "pretty extreme".
"It seems like the Government isn't doing any real cost benefit analysis on these policies, it seems as though they did just cave to pressure from Warner Brothers.
"I am a Tolkien fan and I think it's great for New Zealand that those films were made here in New Zealand, it is probably good for tourism.
"But that doesn't mean that our Government should be handing out hundreds of millions of dollars to film companies that are making billions of dollars."
Jordan Williams, executive director of the NZ Taxpayers' Union, said the lobby group had examined film subsidies and concluded the economic benefits to be questionable.
"If New Zealand is going well out of subsidising the film industry, we'd be the only country that is - because the international literature [shows] that it is a very poor return for subsidising box office films."
Economic Development Minister Steven Joyce defended the spending, and said Peter Jackson's Hobbit movies had generated 3000 jobs during production.
"The total production costs...have been quoted recently at $1.1 billion, much of which was spent in New Zealand.
"The Hobbit movies have been a significant factor in the growth in visitors to New Zealand. In 2014, 14 per cent of holiday visitors to New Zealand selected the Hobbit Trilogy as one of the factors that first stimulated their interest in visiting."
The first two Hobbit movies generated box office takings of about US$1.92 billion, according to IMDb website, and the third instalment in the trilogy, 'The Hobbit: The Battle of Five Armies', was released in December.
Government sweeteners have been a contentious issue with New Zealand pressured to improve the lure of shooting big budget blockbusters locally.
In 2013, Mr Joyce and Arts, Culture and Heritage Minister Chris Finlayson sweetened the pot, lifting the incentive to 20 per cent of production costs, with an additional 5 per cent in the offing for meeting certain criteria designed to put the local industry on a stronger footing.
That deal helped lock in 20th Century Fox to greenlight James Cameron's three Avatar movies to be produced in New Zealand.
The Hobbit film became a political football in 2010, and saw Prime Minister John Key step in to broker a deal with Warner Bros executives amid fears the production could be shipped somewhere cheaper as local actors and technicians sought to standardise and improve their working conditions.
That saw the government give the studios an extra subsidy of up to US$7.5 million per movie for spending more than $200 million, expanding what spending qualifies for the rebate under the existing rules, and changing employment law to classify all film workers as contractors by default.
It would also stump up US$10 million to market local tourism as part of The Hobbit's release.
