The first "three strikes" notices issued to alleged internet pirates have not resulted in action before the Copyright Tribunal, where the accused could have copped a fine of up to $15,000.
TelstraClear and Vodafone confirmed last month they had each sent an "enforcement" notice to a customer at the request of the Recording Industry Association, which represents music and recording artists.
Under a law passed last year, internet providers must issue warning and enforcement notices to customers suspected of illegally downloading copyright content, such as movies or music, if a copyright holder requests it.
After a third notice, rights holders can bring a case before the Copyright Tribunal, which can fine an offender up to $15,000.
But according to intellectual property lawyer Rick Shera, a third notice, the enforcement notice, expires after 35 days and rights holders can only file action against an accused in that time.
