Internet piracy has reportedly halved since the three-strikes copyright law came into effect last year, movie studios say.
However Kiwis still flout the anti-piracy legislation, with 41 percent of internet users accessing "copyright infringing services online" in February, Fairfax Media reported.
The "three strikes" law, which came into effect in September, requires internet companies to issue warning notices to customers alleged to have downloaded copyright content illegally, such as music or movies, if requested by the rights holder.
After a third warning, a case can be brought before the Copyright Tribunal, which can fine an offender up to $15,000.
In submissions made to the Economic Development Ministry and revealed to Fairfax Media under the Official Information Act, both Rianz and the Federation Against Copyright Theft called for the $25 fee paid to internet providers for issuing the notices to be slashed.
