Emergency services are responding to an apparent explosion in central Wellington.
Fire appliances are on scene at the corner of Cuba and Ghuznee streets.
A worker at the Cuba St Night 'n Day store said he had heard an "explosion", and said the
impact of it had lifted up a manhole on Cuba St.
The section of Cuba St where it occurred has pedestrian-only access.
"It was an explosion ... a big bang underground," he said.
It was not known if anyone was injured.
