Warm air causing record temperatures was not the only thing blown over from Australia this week, with Kiwis also getting remnants from bush fires across the Tasman.

Australia, which is also being scorched by a heat wave, is dealing with severe bushfires in southern Tasmania which have destroyed homes and led to health alerts.

MetService told Newshub that smoke particles from those bushfires were responsible for a strange haze obscuring long-distance views in Auckland on Thursday, having been blown to New Zealand by strong westerly winds.

Murray Stewart told Newshub on Thursday that looking from West Auckland there was an "incredible amount of haze to the extent I can't see the CBD, which is normally quite clear".

On January 26, Met Service tweeted satellite imagery showing smoke from the bushfires clearly distinguishable from white clouds hovering over the South Island.
