A network outage prevented Newshub from airing its 6pm news bulletin.
Instead, the network has had to re-air its 4.30pm news and air The Project earlier than usual.
In a statement released to the public, MediaWorks explained its Flower St studio has been hit by a network outage, which prevented it from airing the Newshub bulletin at 6pm as usual.
"Technicians are working on the issue and it is expected that the normal viewing schedule will resume as soon as possible," it said in the statement.
