Ultrafast Fibre Limited was established by WEL Networks Limited in 2010 in order to fulfil a New Zealand Government initiative to rollout ultrafast broadband (UFB) across eight centres in Central North Island.

Responsible for building a 3,000km fibre network, Ultrafast Fibre passed about 163,000 addresses in the urban areas of Hamilton, Tauranga, Whanganui, New Plymouth, Tokoroa, Hawera, Cambridge and Te Awamutu. This represents about 13% of the entire national UFB build.
