Buying a ps4 from USA to NZ volts problem? 10 Points?

Ok so I am keen to get a ps4 from the USA and bring it back to New Zealand but, apparently the volts are different. Will this affect anything? Because I got my iPad from USA and just bought and adapter and it works fine now. So just asking if I bring my ps4 from USA to New Zealand will there be a problem with the volts. thanks
