Check the usual places if you haven’t done so already. Amazon, eBay, etc. (or their equivalents in your country). Also couldn’t hurt to contact WD directly (https://support.wdc.com/contact_phone.aspx) since this is mostly a user to user support forum, to see if they’ll sell you a country specific power supply unit.
If one still has the original power supply they can check if Asian companies/website (where the power supplies are typically manufactured) sell replacements by searching for the power supply manufacturer or model number. Likewise there are some electronics part suppliers that may have compatible power supplies.
Uh I wasn’t saying to use the US Amazon site I was suggesting using the NZ version (if there is one) or as my post indicated “their equivalents in your country”. Since I don’t live in NZ I don’t know exactly how Amazon works in that country, or how they ship things to it. If it ships from the US and or is the wrong wall plug/voltage type, then try another online retailer that is local to NZ or which has cheaper shipping methods to one’s country.
Of course if it is the wrong plug/voltage type and one cannot find the correct wall plug/voltage type for their country from online retailers, and if after contacting WD and WD won’t sell the appropriate country specitic adapter, then one could always spring for an adapter that converts things from one type/voltage to another as a last resort. May cost more money but it is an option.
