I signed up to an auction site. Then I watched cars that came up for auction, and then someone over there would bid for me, up to the amount I specified. That covers it being delivered to your door in NZ (shipping/fees/MAF/insurance). Likely a compliance center rather than your house. Then you just pay for the VTNZ for WOF, and rego. And that's it ! Here's a breakdown from them :
xxxxx yen - 2% surcharge on vehicles over 700,000yen, 4% for vehicles over 1,500,000yen
60,000 yen - our discount FOB if payment received in 3 workings days
(75,000 if received after 3 working days)
5,000 yen - transport from auction house to shipping yard
(can be more if auction is far from yard)
123,113 yen - JACANNA (NZ$1395 + 8500 YEN freight & delivery to your door)
4,000 yen - bank fee
