Forgive me, but if it is a VOR NDB DME approach
It's not a VOR NDB DME approach. The thread title is NDB DME, and it doesn't say anywhere on the chart that VOR is required. It does say that for the DME. Pity the graphic doesn't show the chart title. That would solve it once and for all.
It's pretty logical that it wouldn't "require" the VOR, otherwise there would be no need for the convoluted use of the NDB.

Sounds fun. 5 DME arc? "Stable Capn...apart for the minor heading changes to stay lined up on final!".
