A NZ Post spokeswoman said the company and Kiwibank were consulting staff at the NZ Post Shop & Kiwibank in Gordon Rd, Mosgiel, on proposed changes.
"We'd like to emphasise that no decisions have been made at this early stage.
"We know communities value accessing postal services in locations that are convenient and are nearby to other locations they use for day-to-day activities.
"We always consider these factors before making these decisions. Our involvement in local communities, and supporting their needs is important to us."
She said seven of Mosgiel's post boxes were scheduled for removal, but a further seven would remain at various locations around the town, including the two outside retirement villages.
The post boxes were being removed because regular monitoring over a 22-day period had found low use - including one box which only received an average of 5.5 letters per day.
She said the company constantly reviewed where its post boxes were placed, to make sure they were in convenient locations and were well used by customers.
They were typically situated in places such as petrol stations and supermarkets, where customers visited frequently.
"We always take a number of factors into account before deciding to remove or relocate a post box, including the proximity of other post boxes and high foot traffic."
She said NZ Post was "very committed" to staying in Dunedin and Mosgiel, and providing the communities with postal outlets where people could continue to send parcels, buy stamps and post letters.
Several Mosgiel residents, who declined to be named, said they were concerned about how the loss of the post boxes would affect fellow residents, particularly those with mobility issues.
Another resident said she would be very concerned if the NZ Post Shop and Kiwibank were also lost to the community.
"It would be a bit silly to remove the post shop, because there's quite a few people here in Mosgiel now.
"It's a useful thing for the elderly, who still like to send cards and parcels.
"If you haven't got transport, it's a bit difficult to just go over to Dunedin."
However, one resident said she understood the removal of the post boxes.
"It's a sign of the times. So many people use computers and email for that kind of stuff now."
Mosgiel Taieri Community Board chairwoman Sarah Nitis said it would be of great concern if the NZ Post Shop and Kiwibank was closed, because it would affect a large part of the Mosgiel population who were not mobile enough to travel in to Dunedin to do their posting.
However, she was less concerned about the removal of the Mosgiel post boxes.
"I would assume they've picked certain ones that aren't utilised that much.
"Most people would be able to make it out to the supermarket to post mail."
