Emergency services have closed off part of a busy road in Mangere, South Auckland, after a gas main ruptured.
The NZ Transport Agency said just before 3.30pm Kirkbride Rd, between State Highway 20A and Ascot Rd, would be cordoned off.
The Fire Service were also at the scene.
A northern fire communications spokesman said a gas main had been ruptured by an excavator.
A Vector spokeswoman said the gas was blocked off and repairs were now underway.
