A large scrub fire between the motorway and railway tracks near Porirua has been brought under control, but there are still significant delays for traffic.
State Highway 59 is affected, which is the main route in and out of Wellington since Transmission Gully remains unopened but has officially been named State Highway 1.
Emergency services were called to the scene at about 4pm.
A Fire and Emergency NZ spokesperson said the fire initially stretched between 50m and 100m, however the majority of it has been extinguished and controlled.
