This document 'NZ case study' replaces the earlier submitted document (please delete attachment 'deliverable 11' as I could not do this as a user). The revised document relates only to the NZ case study. A separate document relates to the 'Generic guidelines', submitted as ROI 001591. I have added the GRA logo, Dataman logo and added appropriate acknowledgements. I have discussed this replacement process with Sinead Leahy.
