I'll have a look within the next week or so.

In the meantime you might find the following items
of interest, the New Zealand system is not so
different from the state system in Australia:

the AMPL code and datasets are also available from
their website in PDF and XLS formats / no license as
far as I could see (so treat these as public domain at
your risk)
