European new car prices

[A44RON]

This may have been done to death before, so apologies in advance. Premium European new cars prices, just one example of many:

Brand new Porsche 911 Carrera S purchased in UK, exported to NZ including shipping, GST added on, compliance and all on-road costs = NZ$163,000

NZ New Porsche 911 Carrera S = $235,000

How/why is it $70k more expensive here to buy the same car that's built in the same factory? Where is that figure coming from?

Another example (although not European):

New Nissan GT-R imported from UK, all costs, shipping, GST, compliance etc = $162,000

NZ New Nissan GT-R = $191,000

FYI I've used the average exchange rate from the last 2 years for more accuracy, instead of the post-Brexit figure

Interesting stuff. Always been a huge fan of the M5

Admittedly, the prices quoted above for both are for list price, before any options are ticked for either
