Called Apple, ordered warranty replacement. Said it would take 2 days.
Courier turns up this morning, with this:

(Ipad under A3 sized bag, and the USB portion of the charger on top.
You'll notice there are 2 bags.
Bag 1: USB part of the adaptor, return courier bag and return instructions.
Bag 2: DuckHead (Wall Connector) portion of the adaptor, return courier bag and return instructions.
They only put a hold of $30 on my credit card for this, so if the charger is worth only that, surely the shipping would cost more than its worth? 2 parcels, shipped from AUS to NZ, then back again in different bags. Cant be cheap.
Is this maybe a one off? or is this regular? I've never had more than one thing ordered at once from apple.
Not making a huge deal about it, it was fast and easy processes, but I mean, really..
