I think in the media we see parties described in a way that clashes with historic understandings of where the left, centre & right are purely because the right has been driven so much further to the extremes than 50+ years ago.
I would describe the parties like this:
- TPM: Left
- Green: Centre-Left
- Labour: Centre-Right
- NZ First: Centre-Right
- National: Right
- Act: Far Right
I'm sure some would argue Green & TPM are Far-Left, but neither are really calling for the over throw of the capitalist state or anything so I just don't really see it, i'd put Act at Far-Right because they essentially want to dissolve the power of the state entirely outside of its role in policing internally & externally.
