As IAG NZ ( Insurance Australia Group) has a number of brands under the NZ umbrella; here are a few major ones;

NZI
State
NAC
Swann
Mike Henry
Insurances under ASB & BNZ

I work for the NZI division, and under the business unit of Broker Support.

The structure of the company works like a food chain basically, things get tossed around between the different teams and communication is an integral part. Some of the other business units;

Sales Support
Claims Support
Loss Adjusting
Debt Recovery
Investigator
Broker Claims
Direct Claims

... and shit the list just goes on

As it is quite obvious starting out in such a large multi-national is the shizzz! You get recognised skills & capabilities, build your career portfolio, move on and try out other business units and get all the specialist skills under your belt. An awesome stepping stone indeed.
