Volcanic Ash Advisory Centres in Wellington and Australia say there is no longer any risk of flight disruption from volcanic ash clouds.
Ash from a volcano in Chile affected air traffic for several days until it cleared sufficiently for flights to resume in full a week ago.
The advisory centres say there is currently no ash in the skies that can be detected on high resolution satellite imagery.
The volcano began erupting on 4 June. It is still doing so, but is not sending ash high into the atmosphere.
