A June 2010 report into Industry Sector Productivity Statistics 1978-2008 released by Statistics NZ confirms that the Transport and Storage sector has a very good story to tell in this regard (see in particular Figure 2.1 on page 6).
What is particularly interesting to note though is Figure 14.2 on page 93. I suspect that it could be concluded that the transport reforms in the 1980s were a major contributing factor to the productivity growth in the decade or so following. The more recent productivity performance of the sector has not been so impressive.
