Large swathes of New Zealand have gone offline after an issue with the company responsible for its entire ultra-fast broadband fibre network, which is used by all local Internet Service Providers (ISPs).

Estimates suggest 90 percent of broadband users were left without internet for about four hours.

One provider, Voyager, says identified the issue as being caused by the “Chorus Wellington UFB (ultrafast broadband) handover.”

Chorus, once part of Telecom NZ before it was split into two (the other part being Spark, an ISP) owns and maintains the fibre backbone of the whole country. Social media has been flooded with businesses advising their operations are at a standstill.

Chorus has released a statement saying services have started coming back online, while revealing “human error” was behind the blackout.

This is a developing story.
