Despite concerns over recent months that internet companies will not have enough time to get ready for the law, a number of providers contacted this week said they were prepared.
Slingshot chief executive Mark Callander said the company was ready and waiting for the regulations and in a position to cope with the regime.
The head of TelstraClear's copyright team, Ewan Cowie, echoed this sentiment and said the company had a system ready to go live.
However, Orcon chief executive Scott Bartlett said he was nervous about the amount of notices that might arrive and was concerned his firm could become swamped.
"Our hope is that rights holders only focus on the most egregious of copyright infringers and don't dump thousands of notices on [internet companies]. We honestly just have no idea what kind of volume [of notices] is going to come through, it could be 100, it could be 1000," he said.
Fuelling Bartlett's concerns is the fact Orcon will need to manually process and send warning notices to customers.
It would be at least another three months before the company would have an automated system running to deal with each notice, Bartlett said.
Telecom's Anna Skerten said one of the main concerns with the law was the uncertainty over how many notices rights holders would send.
"We have tried to engage with the major rights holder groups to make sure we have sufficient capacity to cope with the notices they intend to send, but no firm estimates have been given to us," Skerten said.
The New Zealand Federation Against Copyright Theft (NZFACT), which represents the Motion Picture Association, could not be reached for comment.
