  We have used the Cornish radio catalogue combined with the use of
multi-wavelength data to identify 62 new Planetary Nebula (PN) candidates close
to the Galactic mid-plane. Of this sample 11 have weak optical counterparts in
deep narrow band H$\alpha$ imaging that allows their spectroscopic follow-up.
We have observed eight of these candidates spectroscopically, leading to the
confirmation of 7 out of 8 as PNe. All but one of our sample of newly detected
PNe appear to be of Type I chemistry with very large [NII]/H$\alpha$ ratios.
This indicates that our selection method heavily favours detection of this kind
of PN. Cornish is a low Galactic latitude survey where young objects and Type I
PNe (thought to derive from higher mass progenitors) are more plentiful, but
where optical extinction is large. The very high success rate in correctly
identifying PNe in this zone proves the efficacy of our radio and multiple
multi-wavelength diagnostic tools used to successfully predict and then confirm
their PN nature, at least in the cases where an optical counterpart is found
and has been observed. The study reinforces the effective use of a combination
of multi-wavelength and optical data in the identification of new Galactic PNe
and especially those of Type I chemistries whose dusty environments often
prevents their easy detection in the optical regime alone.
