Police are continuing to scour central Auckland suburbs to find a woman missing since last week.
Cindy Li, 70, has been missing since the morning of 9 November when she left an address on Tranmere Road, Sandringham, on foot.
Police said an extensive search effort had taken place in the areas nearby since she was reported missing.
They are still trying to establish her movements since leaving the area, and where she headed afterwards.
CCTV footage and follow-up information from the public was being reviewed at by police.
Detective Senior Sergeant Geoff Baber said police had significant concerns for Li's safety, given her age and the length of time she had been missing.
"We have a large team working hard to piece together Cindy's movements and locate her.
"There is no evidence to indicate foul play is involved but we continue to appeal to the public for any information about her disappearance or any sightings of Cindy since Tuesday."
Anyone with information can call police on 105, quoting file number 211110/4026
