An enormous wall of dust which has swept over New South Wales and Australian Capital Territory is making its way over the Tasman Sea towards our shores.
MetService reports the dust is visible from satellite imagery.
Western parts of the South Island could be hit by the dust wall tomorrow.
Strong northwest winds are picking up large areas of the dust, MetService said, ahead of a cold front.
Other parts of the country could be hit, including central New Zealand, which would not be reached until Friday.
