Police have cordoned off parts of northern Wellington suburb Khandallah after contractors broke a gas main.
The Fire Service said the pipe, near the intersection of Khandallah and Cockayne roads, was hit at 10.50am.
Fire personnel have not located which main had been hit and nearby houses have been evacuated.
At 2pm police returned to the scene and cordoned Khandallah Rd between Simla Cres and Cockayne Rd, and at Clutha Rd and Cockayne Rd, only allowing residents access to their homes while the rupture was dealt with.
Powerco Gas operations manager Don Elers said the gas main leak occurred when a civil contractor damaged a section of Powerco's gas distribution network.
Mr Elers said an investigation into the circumstances surrounding the gas leak would be undertaken over the next few weeks.
He said anyone planning on excavating in a location with a reticulated supply of natural gas must locate buried gas lines before beginning work. He advised people to go to the company's website to obtain details on how to locate underground services before they started digging.
"It's a simple measure to take to ensure you are safe, which is Powerco's main priority," Mr Elers said.
