I believe for Wellywood one has to be born here to be considered a local.
In Christchurch your family has to have been from one of the four ships to be a local.
In Auckland, no-one's a local.
The amount of Wellingtonian natives I know I can count on both hands, most people are from out of town here - don't know what Junior is on about. Maybe its just where I work and who I know, if you go to school here I expect you would know plenty.
