Search co ordinator and family spokesman Manu Panirau said two boats searched Otago Harbour yesterday, and the family and about 20 volunteers searched an area between Maori Rd and Serpentine Ave, including Jubilee Park.
Search and rescue co ordinator Senior Sergeant Brian Benn, of Dunedin, said the search by the family and community was ''fantastic'' and he struggled to recall such an extensive search effort in Dunedin in the past 30 years.
''I don't recall a search that has mustered so many searcher hours in Dunedin.''
The family and volunteers would search another ''area of interest'' today, Mr Panirau said.
The family was holding up ''really well'' with the support of friends.
''Eventually, we are going to have to face the reality of what has gone on the past six or seven days but we haven't given ourselves time to work through that because we have been so busy looking for her,'' Mr Panirau said.
The family was ''appreciative and thankful'' of the support from the community.
''It has been overwhelming, not just the support from family and friends but the Dunedin community itself.''
Snr Sgt Benn said members of St Kilda Surf Club planned to make a coastal search by inflatable boats between St Kilda and Boulder Beach today.
On Saturday, police and search and rescue crews searched private residential addresses within a 300m radius of Carroll St, Mornington, where Mrs Potter was last seen on March 30.
The search involved four teams made up of police staff, search dogs and volunteers.
On Saturday, the family ''mobilised'' the community to search public areas including bush areas, parks and coastlines.
''We wanted to complement that by searching the private property,'' Snr Sgt Benn said.
After Easter, he expected the search effort to be peer reviewed by ''an outside expert''. The parks and coastline were being searched because missing people would often go to a secluded place with a view, he said.
Areas of interest were searched three times before other search areas were considered, he said.
