Until municipal administrative reform in Rhineland-Palatinate in 1969, both centres belonged to the Bernkastel district, whose seat was in Bernkastel-Kues.

The municipal election held on 7 June 2009 yielded the following results:[5] The mayor is Dirk Doppelhamer (SPD).

Neumagen's arms might have been described thus: Per pale argent a cross gules and barry of thirteen of the first and azure, that is to say, with a red cross on a silver background on the dexter (armsbearer's right, viewer's left) side and thirteen horizontal stripes alternating between silver and blue on the sinister (armsbearer's left, viewer's right) side.

[6] Dhron's arms might have been described thus: Per pale argent a cross gules and gules a bend argent charged with three roses Or barbed vert, that is to say, with the same dexter side as Neumagen's arms, but with the sinister side showing a red field with a silver slanted stripe with three golden roses with green sepals running along it.

The resulting escutcheon might be described thus: Barry of eleven argent and azure the Neumagen Wine Ship Or, in a chief of the first a cross gules charged with three roses in fess of the third.

The blue and silver stripes stand for the old feudal lords of Neumagen, and the Wine Ship for the municipality's Roman beginnings.

In the centre of Neumagen is found a cast of the Roman Wine Ship right next to the old Saint Peter's Chapel (Peterskapelle) and the Ausonius Garden.

Farther up the Moselle is found the new cycle path which leads straight to the Rosengärtchen vineyard with its archway of roses and its Märtyrerkapelle ("Martyrs' Chapel").

Neumagen-Dhron has at its disposal its own yacht harbour, and by way of a landing stage, passenger voyages, for instance to Bernkastel-Kues, are possible.
