• The data service was used by regional authorities in New Zealand to respond to central government funding initiatives.
• Specifically in response to central government funding for FTTH deployment (UFB) and rural broadband extension (RBI).
• Network coverage could be integrated into their GIS systems.
• Maps for public consultation could be produced.
• Network providers could be identified.
