Hi, I have said many times that is actually illegal for anyone to be commercially selling electrical products with any overseas plug and having to use a NZ adapter plug. This is can void your insurance of your house if you have a fire or at least the accessor can use it against you and not pay out!!!!!! These people from that way that bring these in on the cheap and sell on TradeMe....
You can request the Aust/NZ plug with the Australian electrical standards certificates, (that is why there are the certificate numbers imprinted by the pins on the NZ plug) however you will find that if these buyers went to the Jebo company and ask for the Aust/NZ plug, they will not sell to them as there is a Jebo authorised agent in Aust/NZ.
They are then only able to purchase on the domestic China market. Hence the China pin pattern.
So these so called importers bring in these imported electrical products, then its buyer beware!!!!!!
