In addition, employment projections for 2006 have been generated using BERL's computable general equilibrium model of the New Zealand economy and utilising externally sourced information on projections of export demand, productivity and a range of other economic indicators over the medium term. It is envisaged that these employment projections will be modified, updated and refined on an ongoing basis using additional and new data as it comes to hand, as well as integrating Career Services own information sources into this process.
