Millers Flat is a small town in inland Otago, in the South Island of New Zealand.

Although some people chose not to answer the census's question about religious affiliation, 48.3% had no religion, and 41.4% were Christian.

[5] Approximately 8 km downstream of Millers Flat on the Clutha River are the remains of the Horseshoe Bend Gold Diggings, now largely remembered for the story of "Somebody's Darling" and the Lonely Graves.

Early in 1865 the body of a young man was discovered at Rag Beach, upstream and on the opposite side of the river from the present site of the Lonely Graves.

An inquest held on 22 February 1865 in the Horseshoe Hotel determined the body to be that of Charles Alms who had fallen in the river at Mutton Town Creek, some considerable distance upstream.

Later in that same year a miner named William Rigney arrived at Horseshoe Bend, and with John Ord erected a fence of rough manuka poles around the previously untended grave.
