The worst case scenario with NZ's new internet file sharing law was that a few chumps would get punished, while hardcore downloaders would simply change their tactics.
But that's what seems to be what's happening.
The first wave of infringement notices were sent under the Copyright (Infringing File Sharing) Amendment Act in November last year, following months of publicity about the new "three strikes" law.
My anecdotal experience is that, so far, many casual users have not been scared off by the Act - possibly because of the relatively small number of notices sent so far (a function of the fact that, at least for the first year of the law, ISPs can charge a copyright holder, such as a movie studio or record copy, a $25 fee for each notice sent. Rights-holders say that's too much).
I was at a BBQ recently, where I was in a minority - being the only person who actually paid for his movie loads (well, at least to the degree I only break Apple's iTunes terms and conditions, rather than the law, with my iTunes US subscription, which allows me to buy more movies and TV shows than are available on iTunes NZ).
I'm constantly shocked that so many otherwise upstanding, law-abiding middle class citizens illegally download movie and TV content - still citing the moral argument that it's okay to do so since so little street-legal online content is available to New Zealanders.
One person I spoke to said, "I'm just waiting for my first letter". He was using RapidShare, and not making any attempt to hide the fact from his ISP (which would have to probe his usage details if it received a notice).
Below, Donald Clark - a former head of the government broadband network company Reannz, and a former advisor to the Prime Minister, summarises University of Waikato research that shows sophisticated internet users have simply switched the way they download material, using software and services that cover their tracks.
"It’s hard to escape the conclusion that people sharing copyrighted material have simply switched mechanisms," Mr Clark concludes.
"I suspect that there has been little net-change in the sharing of copyrighted material."

NZ Legislation shifts file-sharing from bittorrent to tunnels
The last week in January was NZNOG’s - the NZ Network Operators' Group - annual meeting. It’s the place where the people who design, build, and operate ISPs, telco and Internet infrastructure get together to argue.
The group has come up with a new way of measuring traffic so that they can tell (with a pretty high degree of accuracy) what *type* of traffic any particular packet is part of without having to fully unwrap the packet and open up the box. Think of it like looking at the postmark, and then giving the parcel a bit of a squeeze!
They call this technique “mildly penetrative packet inspection” (as opposed to “deep packet inspection”). It’s key features are:
- Requires only 4 bytes of application payload instead of full DPI
- Examines first payload-bearing packet in each direction only
- Classifications based on payload signatures, size and ports
- This all results in a much “lighter” measurement burden, whilst still achieving 95% accuracy (or 70%-80% when port 80 flows are excluded). This places it well above other packet-inspection-lite approaches.
Measured impact of legislation
Crucially, the WAND team managed to take some measurements in January 2011, and then again in September 2011 and January 2012 - ie the measures straddle the dates when the new File Sharing law came into force in NZ!
Does the data show a change in online behaviour? Oh yes.
(Click to enlarge.)
We can see that while overall traffic has remained fairly constant, so can conclude that end-user activity hasn’t altered significantly.
We also see that, immediately following the law coming info force on 1 September 2011, there was a 75% reduction in measured peer-to-peer traffic, and this was sustained into January this year. Newsgroup traffic (a large source of file sharing) has dropped to almost zero!
However, there was a more than doubling in secure tunneling and remote-access protocol traffic volumes.
It’s hard to escape the conclusion that people sharing copyrighted material have simply switched mechanisms - from bittorrent to technologies like VPN, SSH or the use of file downloading services (yes, like MegaUpload) and seedboxes in other jurisdictions.
I suspect that there has been little net-change in the sharing of copyrighted material and that the answer remains business models that make it available easily and at reasonable price - that’s why Netflix (online movie service) accounts for 1/3 of total internet traffic in the US!
The Internet interprets censorship as damage and routes around it. Legislation will never be able to keep up with technical innovation.
