More than a year after a Senate committee looking into the National Broadband Network convened, the government has issued a scathing response, rejecting a third of its recommendations.

In September, the committee published a report expressing concerns about a range of issues, including poor consumer experiences, and issued 23 recommendations for improvement.

The government has disagreed with nine of those, saying some were "unnecessary", and describing the overall report as "misdirected".

"The government is disappointed that after considering 191 submissions; holding 15 public hearings; receiving testimony from 179 witnesses; and undertaking three site visits, the committee's majority report and recommendations indicates a failure to understand the fundamentals of the NBN," the response said.
