The MVR contains details of every vehicle and its owner. Details can be obtained by quoting a registration number plate.
1 NEWS has obtained figures from the NZTA under the Official Information Act that show a striking pattern. A spike in requests from Thompson and Clark to access the register coincides clearly with heightened activity from Greenpeace and other environmental groups.
For example in Jan/Feb 2013, the Rainbow Warrior was visiting New Zealand. In January 2014 there were extensive protests mounted when oil company Anadarko's drilling ship was in New Zealand waters.
Mr Norman says: "It's pretty plain that Thompson and Clark are using their access to the register as a kind of trawling tool to identify people who were involved in protest action".
This is illegal: TCIL was granted access to the register for a number of very limited purposes, and "spying on protesters" was not one of them. Access was also on the basis that information was not passed to third parties. Interestingly, they've since had their access removed - something NZTA says is common where there has been inappropriate use. Apparently there's a $50,000 fine for abuse of this information, but we can be certain the police will never prosecute: Thompson and Clark are on their side, and so the police will simply look the other way on their crimes, just as they do for crimes committed by their own officers. If Greenpeace wants justice, they'll need to seek it themselves by civil action or private prosecution.
