An eight-year-old girl was pulled "shaking and cold" from the Manukau Harbour after at least three hours in the water this evening, while a 52-year-old man is still missing.
It is believed the pair had been out fishing together when their dinghy capsized.
Emergency services suspended their search for the man around 11pm, after more than six hours, but will resume looking for him in the morning.
Rescue services began searching the Papakura channel area of the Manukau Harbour after a member of the public found a small boat adrift and upturned with no occupants at around 4.30pm.
Police, Coast Guard and Westpac Rescue Auckland have been conducting air, sea and land searches. Just after 7pm Coast Guard volunteers in the Papakura Rescue One boat found the eight-year-old girl treading water in the harbour.
