I saw that but I wasn't sure about the warranty: 

"This product may contain warranty documents on or inside the packaging provided by the manufacturer of the product. Any such warranty is not given by Dick Smith, and is separate from the Dick Smith Customer Charter. Some warranties provided by manufacturers of imported goods may not apply in New Zealand. You should contact the manufacturer identified on the warranty document to determine whether or not the warranty applies to the goods in New Zealand and if so, how you should go about making a claim under such a warranty."

I assume the Dick Smith are imported from Australia, does anyone know if the warranty covers NZ as well?
