In a media release dated 26 May 2015, Chorus says:
UFB has the potential to transform Greymouth's economy and the way it connects to the rest of the world," Chorus General Manager of Infrastructure Ed Beattie says.
"The benefits of a UFB-connected business are widespread. There is growth from improved productivity, lower travel costs, greater flexibility for people to work from home, lower network and ICT expenses, and savings from moving applications into the cloud.
Another bonus is the ability to communicate more easily and efficiently with suppliers, customers and business partners on a global scale.
We're already starting to see some of these benefits in Greymouth. Businesses already connected to fibre are experiencing seamless cloud computing, they're sending large images and files, conducting meetings over smooth HD video conferencing and hosting multiple users and devices, all on the same Internet connection.
UFB is also making an impact in Greymouth homes, particularly with the rapid rise of online TV, high definition movies and gaming. UFB allows multiple users in a home to be connected to different devices, and streaming content all at once, with no buffering or loss of connectivity.
