With regard to the Nissan Leaf, owners of second-hand imported Leafs have faced many issues that wouldn't have been present if they had been able to buy NZ-New Leafs. For example, the navigation system may not have NZ maps and may be written in Japanese. The stereo systems etc may have to be adapted to NZ conditions.
And worst of all, it took Nissan NZ a long time to come to the party with updated firmware for 30 kWh Leafs to "solve" the fast battery degradation problem! In the meantime, some 30 kWh owners paid $250 to get their Leafs updated by third party software that still hasn't been approved by Nissan! So these owners are now faced with paying an official Nissan dealer to overwrite the third party firmware with Nissan approved firmware. None of this would have happened if Nissan NZ had marketed the 30 kWh Leaf as new in NZ, but they didn't do this.
I don't feel that is relevant, could happen to an ICE car, washing machine, things happen.
I think it's relevant because, with a NZ-New vehicle, the manufacturer's warranty gives the owner peace of mind in that things that go wrong will be put right. But, with imported second-hand cars, the dealers who sold the cars have not been obligated to provide, for example, NZ maps written in English or stereos that work properly in NZ. So, some Leaf owners have had to pay third parties to do this work for them.
