The traffic signal fault in Christchurch which caused significant delays this morning in the CBD has now been fixed.
Originally thought to have been caused by this morning’s earthquake, the actual cause of the fault is still not known.
It began around 10 last night.
Christchurch Transport Operations Centre says congestion is now expected to ease.
It says the signals team is working with the Christchurch City Council’s IT department to find an exact cause.
Earlier this morning the strong quake woke up most of Christchurch.
