The body of an elderly woman has been found on Dunedin's St Clair beach this morning.

The body was found near the wooden piles on the beach by a man walking his dog.

The man contacted emergency services after discovering the body above the tideline just after 6am, Southern police district deployment co-ordinator Senior Sergeant Matt Scoles said.

"The woman was deceased and we cordoned off a reasonably large area of the beach.''

She was found clothed and with no identification. Detectives are at the scene.

There had been no reports of a missing person fitting her description, he said.

The death was not believed to be suspicious "at this point in time''.
