Fewer than a third of properties passed by the National Broadband Network in Coffs Harbour have taken up the new service, despite plans to begin switching off the copper network later this year.

NBNCo says more than 24 thousand properties on the Coffs Coast are now serviced by the national broadband network.

More than 19 thousand will lose their copper services between July this year and January next year.

But according to figures provided by NBNCo, only 7 thousand have taken up the new service.

In a statement, an NBNCo spokesman said they are working with all stakeholders to ensure the community is aware of the need to switch over.

"For the past 12 months, NBN Co has been working with a range of stakeholders to ensure local residents and businesses in the Coffs Coast are aware and have the necessary information needed ahead of migration to the NBN," he said.

"Such activities include local advertising, community information sessions and direct mail."

Cowper MP Luke Hartsuyker this week described the rollout of the NBN on the Coffs Coast as "shambolic", after receiving numerous complaints from residents about problems making the switch, and using the service.

He said if the situation does not improve, the switch-over could be delayed.
