Meanwhile, searchers in New South Wales have found a man's body near the wreckage of a light plane that crashed in the state's Illawarra region.
The crashed single-seater plane was found less than two hours after the search resumed this morning in dense bushland between Bulli Tops and Sublime Point at 6.30am (8.30am NZT).
Police say searchers found the body of the man, 57, in the area where the plane came down.
The hunt for the plane was sparked after a resident reported a loud bang in the area at about 7.45pm (9.45pm NZT) on Tuesday.
The single-seater aircraft with one man aboard was reported missing after taking off from Wedderburn Airport, between Sydney and Wollongong.
