Mid-2008 iMac Voltage conversion?

I have a mid-2008 iMac (9L31a), purchased in the United States. My wife and I plan to move to New Zealand in June 2012. The chart on Apple's site claims that my iMac is Auto-Switching, but the power cable says this: "10A 125V~" That makes me hesitate.

Will I be able to take my iMac "as is," put an outlet converter (not a voltage converter) on the current cord, and plug it in my wall in New Zealand without frying the machine? Thanks!
