Label too much for this Westie

I think I have had enough of the "Westie" label so I wonder what's with this demarcation point of Auckland people who live out West are Westies.   Having lived decades in Mission Bay area and I guess I could be termed a 'Eastie' as I do not drive a Ford or Holden, I am always well groomed, and I prefer a modern glass cube of a house. No sandals, no beer in the fridge, no dogs chained, snarling, to the leafless tree in the barren garden. However there are no coins for Easties, Southies, Northies or Centralies for Aucklanders yet.
