BTW, I haven't tried it out, but Blender has a scale multiplier when importing or exporting. You might just be exporting the mesh 10x higher, which suspiciously enough is the same as the default value for that multiplier.

My first failed attempt was scaling down the object vertices, however object scaling worked perfectly.
In Blender, use object scaling to get the desired size results. No scale modifications required in NifSkope
I'll be editing the top of this post for quick access to the answer of this problem for impatient people like myself
