"We're still considering our options at the moment, but for the Copyright Amendment Act to be workable so that rights holders can equitably protect their works, several provisions do need to be reviewed, including the high cost of issuing notices," Eaton said. "In the interim, we're committed to supporting the legislation where we can and have launched a national education campaign to support its introduction."
Internet companies can charge rights holders $25 for each notice sent.
"We do believe a workable solution can be found moving forward," he said.
NZFACT was established in 2005 by the Motion Picture Association, an organisation which "serves as the voice and advocate of the American motion picture, home video and television industries".
NZFACT members include Village Roadshow, Walt Disney Studios, Paramount Pictures and Warner Bros.
The Government's "three strikes" law requires internet companies to issue warning notices to customers suspected of illegally downloading copyright content - such as movies or music - if a rights holder requests it and pays the fee.
After a third notice, rights holders can bring a case before the Copyright Tribunal, which can fine an offender up to $15,000.
TelstraClear, Telecom, Orcon and Vodafone said yesterday that they had not received any more notices.
Orcon chief executive Scott Bartlett said he expected the notices would come in weekly batches.
