A survey by a movie industry veteran shows New Zealand special effect workers put in longer hours than many other countries.
The survey of 30 countries showed that only 3% here do a 40-hour week, with the rest doing 50 to 80 hours and up to 100 hours during busy periods.
Scott Squires has been in the industry for 40 years.
He told Nine to Noon that Hollywood film studios are making more demands and offering less pay, driving special effect companies out of business.
And many visual effects experts are being forced to leave the industry because of difficult work conditions.
