Mother of three Laura Singh, who was missing for five days, is undergoing medical assessments after she was found in Wellsford yesterday.
Ms Singh, who went missing from her Greenlane home on Monday, was found around 1pm.
Auckland City Police communications manager Noreen Hegarty said Ms Singh turned up at a business in Wellsford and staff contacted police.
People at her Greenlane home yesterday declined to comment on Ms Singh's disappearance and said she was still being checked over by doctors.
Detective Senior Sergeant Paul Newman said the fact that she was able to be reunited with her family this weekend was a fantastic end to a stressful week for all involved in trying to find her.
"Laura will, as a matter of course, be assessed by health practitioners and, when the time is right, we will speak with her to establish what's been going on for the past four days."
Her sister Angela Kneeshaw said the family sincerely thanked the public, police and the media for their help finding her. Ms Singh's vehicle had also been located and had been secured by police. Colleagues at her Mt Eden workplace said they were relieved she had been found.
Appeals for information about Ms Singh's disappearance had reached more than 80,000 people.
Mr Newman said officers had not seen any indication of foul play at Ms Singh's home. She had been having a text conversation with a friend until just after 8pm.
Billboards appealing for sightings were due to be put up around Auckland courtesy of NZME. and the Department of Conservation had been asked to distribute flyers to its North Island field staff.
Ms Kneeshaw said her disappearance was totally out of character.
