I think the focus on cars is a bigger problem than what energy source they use. EVs are taking over anyway, there is no standing in the way of that.
If we want to reduce emissions (pollution isn't much of a problem in windswept NZ) then we need to focus on more efficient modes of transport and lifestyles. Not more cars.
We will still be able to import used EVs from Japan, if converting our domestic fleet is a goal.
Seems like a good move. It's a crap dynamic at this point. Maybe later we could re-federate once the numbers aren't so skewed. If people from there feel the need to discuss NZ issues they still have options. They can join here. They can make their own NZ sub if NZ issues are so important to them.
