According to wiki NZ comprises 600+ Islands, but of the 1133 All Blacks to date roughly 95% were born on just 2, the unimaginatively-named North & South. In the early days a few came from the islands of Britain & Ireland, in more recent times there have been more from there (e.g. Jamie Salmon & John Gallagher) plus a few from Australia (more correctly a Continent than an island, but it is girt by sea so close enough IMO) such as Steve Devine, plus about 25 from the archipelagos to the north, sometimes referred to as The Islands, other times as Samoa (both the American & sovereign parts) Fiji & Tonga. Here endith the geography/ history lesson.
