Mrs Potter went missing from her daughter's Carroll St home in Dunedin about noon on Monday, March 30.
Police and private searches have failed to find any trace of the 53 year old woman.
An aerial search was carried out from Tunnel Beach to Boulder Beach _ a distance of 20km _ and the upper Otago Harbour area yesterday afternoon.
''Nothing was found from the air,'' Dunedin Police search and rescue co ordinator, Senior Sergeant Brian Benn, said.
A police shoreline search would continue today, while the family were also searching the upper harbour.
Police would be reviewing the search but it was too soon to say if would be the last aerial search, he said.
Mrs Potter was last seen wearing dark blue denim jeans, a two toned black and grey long sleeved three quarter buttoned shirt with white cuffs, and no footwear.
She is described as slim with light brown, collar length hair.
Anyone who might have seen Mrs Potter, or knew where she was, was asked to contact Dunedin police on (03) 471 4800.
