Yes the imported file in Aperature had the focus points.
It seems that this meta data is not catalogued in iPhoto because it doesn't support this feature and Aperture just piggy backs off this info.
Since I knew the info was there, I then simply chose:
Metadata -> Update from Original in Aperture and the focus points was available.
Not as integrated as I'd like but at least the info isn't gone and is relatively painless when I want to view it.
Thanks for the help.
