Flights to and from Darwin are resuming after being grounded by an ash cloud from an Indonesian volcano.

The Darwin Volcanic Ash Advisory Centre said the plumes affecting Australian airspace are clearing over the Darwin region as the afternoon draws on.

Darwin was completely cut off to all air services yesterday as three separate ash plumes billowed from the Sangeang Api volcano, off the Indonesian island of Sumbawa.

But while it's caused major delays to flights across the Tasman, Air New Zealand says none of its operations to Indonesia or Australia has been delayed.


An Air New Zealand spokeswoman says the airline's flight paths weren't affected by the ash cloud.
