The first stage will be completed in July.
"That's also the time that Wanganui businesses will be able to start using the new network," Ms Elliott said.
She said the fibre currently being laid, which is thinner than a single human hair, would deliver noticeably faster broadband than was currently available, for a similar price.
"We're talking super-high speed. It starts from 30MB per second and goes up from there.
"There's no limit on top speed, other than the limitations of the electronics."
Ms Elliott said multiple users in a neighbourhood would not slow the ultra-fast broadband down, as is currently the case.
But Ms Elliott said fast broadband was only the beginning.
"We can't even imagine what some of the potential future uses for this fibre might be, particularly for entertainment options."
She said telephone, broadband, and entertainment packages such as Sky could all be delivered through the fibre.
Ms Elliott said support for the fibre was high in Wanganui, and her sense was people were keen for it to be up and running.
She praised the Wanganui District Council for its role in bringing ultra-fast broadband to Wanganui.
"We have a close relationship, a good relationship, with the council. It's been very positive," she said.
The Wanganui project is estimated to cost $35 million, while the nationwide roll-out is costing the Government $1.3 billion.
