A gas leak in Auckland’s Takapuna has prompted emergency services to cordon off Killarney St, causing heavy traffic in the surrounding streets.

Fire and Emergency New Zealand is responding to the leak while police direct motorists.

Police closed Killarney St between Lake Pupuke and Anzac Sts.

Traffic has backed up onto Taharoto and Lake Rds, Anzac and Auburn Sts and The Terrace.

It is the second gas leak to plague Auckland in less than a week, after people were told to evacuate the downtown area last Thursday evening.

An emergency mobile alert was sent to phones at 5.45pm on Thursday, telling people to close all doors and windows.

Part of Customs St was cordoned off from Albert St. Beach Rd was also closed up to Anzac Ave.

A Herald reporter said the “smell of gas is very strong on the corner of Customs and Commerce”.
