Christchurch residents have been hit with a power cut on Thursday afternoon.
The power outage has affected at least four suburbs, including Addington, that has forced the evacuation of Horncastle Arena which is currently preparing to host the Canterbury Home Show opening on October 14.
Other suburbs affected were the central city, Riccarton and Spreydon.
An Orion spokesman told Newshub originally as many as 4000 customers may have been affected but that number has now been contained to 198.
They say teams are still out working to get the power on to the remaining customers, however are unsure of how long it may be before power will be restored.
