Colombo St has reopened to vehicles after a gas leak closed the central Christchurch thoroughfare.
Christchurch Transport Operations Centre (CTOC) reported there was a gas leak and southbound lanes on Colombo St had been closed at the intersection with Armagh St.
Motorists were asked to avoid the area until it was resolved.
A Fire and Emergency NZ spokesman said the leak was coming from a gas main, but they were not sure of the cause.
"We currently have two appliances on scene and they are ensuring that the gas dissipates.
