No offense to Kiwi, but you must be one of the shorter guys in NZ. Those maori's and co. are ginormous.
None taken buddy. And you're right about the Maoris and Polynesians, especially Samoans and Tongans. I've got heaps of mates who are Samoan (and Tongans too) and the average size of these guys is something like 6'1", 230 lbs(current generation). Tongans are even (slightly) bigger and are apparently the biggest race on earth.
Saw this Tongan guy once in my old gym. He was about 6 feet even and about 225 - 230 lbs, with terrific lines and about 14 - 15% bodyfat. And he was benching 3 plates for reps. Anyway, I went up to him to have a chat and asked him if he took any Protein or other supplements. And he goes "What's protein?" LOFL!
I tell ya, if you took some of these guys and put them under proper supervision (training, dieting etc), some of them would morph into absolute monsters. Unfortunately, while a lot of them show casual interest and respect people who're built, the majority (probably 80%, if not more) of them just f*ck around in the gym either cause they aren't that interested or mostly because they don't know what they're doing

. And of course, most of them turn to sports like Rugby in which they can make money.
