There are no problems with the either the pace of the roll-out of the National Broadband Network nor its budget, Malcolm Turnbull told the Parliament on Monday, following publication by Fairfax Media of a leaked internal progress report suggesting multiple ongoing delays.

The confidential internal progress assessment marked "for official use only", identified a series of construction problems within the complicated multi-technology project.

These ranged from delays in connecting electricity to the node points in streets, to design hold-ups and other material or skills shortages.

A government source scoffed at the problems, declaring many simply arose and were then resolved in a timely fashion within weeks.
