We saw this Large white fly in Northland NZ on 07/01/13 and wondered what it is. It was very placid and wasn’t afraid of us at all, in fact it jumped from the piece of wood we photographed it on, onto ond of us!! I have never seen one in New Zealand before. It was quite large and bigger than a typical NZ house or Blow fly.

This is a Horse Fly or Gadfly in the family Tabanidae, a group that is commonly called March Flies in Australia. The Insects of Tasmania website has several unidentified species that look very similar to your individual. Female Horse Flies bite and feed on blood from large warm blooded animals, including people if there is no other food source, and males feed on nectar.
