Waikouaiti has been down to one constable since the departure of Constable Jon-Paul Tremain at the end of 2014.
Other changes proposed are additional sergeants in Oamaru and Balclutha and an additional detective for South Otago.
Otago Coastal area commander Inspector Jason Guthrie said proposed changes would position police to take a more co-ordinated approach to prevention of family violence and alcohol issues, while improving service.
"These proposed changes are very much about enhancing service delivery to the wider community and keeping the people of the wider Otago coastal policing area safe,'' Insp Guthrie said.
"Police operate in a very dynamic environment and continually review the way we serve our communities and where appropriate, we will make changes to our structure to provide an improved service.''
Under the proposal, the area would maintain its present strength and no stations would close, he said.
A review was also being conducted at the moment in western Southland, Insp Guthrie said.
The last major restructure of the Otago coastal area was in 2013 when the national prevention first strategy was implemented.
Many officers had to reapply for their jobs and compete for positions and about 20 of the 637 staff at the time were formally advised their positions were affected.
New Zealand Police Association southern regional director Mike Thomas said the association had been consulted on the proposal and it was aimed at providing more supervision and back-up for front-line staff.
A final decision on any changes is expected to be made within two weeks.
