Where can I find an administrative boundary shapefile for Monaco?

Question

I am looking for an administrative boundary file (preferably in ESRI shapefile format) for the divisions of Monaco namely:

Condamine
Fontvieille
Jardin Exotique
La Rousse
Larvotto
Les Moneghetti
Monaco-Ville
Monte-Carlo

I have looked at a few websites like diva-gis, nationmaster, geofabrik, statsilk and eurostat but non of the files for Monaco are divided by the above areas, only the outline of Monaco itself. I need something akin to this image below...

Where did you get that image from? It might not be too hard to just digitise the boundaries from it - take care on that skinny bit along the harbour though... — Spacedman, Nov 05 '15 at 15:49
OpenStreetMap has some of those admin boundaries, but not a complete set, it seems... — Spacedman, Nov 05 '15 at 16:11
