This created two imperatives.
Transit not only wanted to have the first toll road, it wanted to be responsible for all future toll roads, because of the need to establish a whole range of functions and activities it hadn't undertaken before - in particular customer service and billing.
Finally, the National government, to be fair, had nothing to do with any of this, because it was all over bar the ribbon cutting when the 2008 election happened. This was a Clark Administration special. However, it is rather poor form for the Nats to not contain things now. I have three simple recommendations:
1. Put the Transport Registry Centre of NZTA up for sale (with the toll system) keeping data management of the driving and motor vehicle licensing databases in-house and separate.
2. Require NZTA to outsource provision of tolling services for any future toll roads by competitive tender;
3. Put the Northern Gateway Toll Road up for sale (or even lease for 50 years).
