Firstly NZ customers are being told that all returns must be sent back via
Trackable Courier only (preferably via CourierPost). Customers must keep a
record of the Courier Tracking details for their old battery. Customers will
not be sent a new battery until the old one is returned to Apple Australia.
The reason that Apple Australia will not ship replacement batteries (in New
Zealand) without getting your old battery back first is that Apple Australia
requires New Zealand resellers to send the bad battery back to them within
10 days of them shipping the replacement. If they don't receive the battery
within that time frame, they will then charge the service provider the full
price of the replacement battery (about $150NZ). New Zealand resellers
refuse to be held at gunpoint with these ridiculous time frames and
requirements. These resellers did nothing wrong so why should they be held
financially responsible.
