Yeah but there is a new Special Interest Vehicle law.

The R33 GTR meets all of the following criteria:
# The vehicle's make and model has been (or was) manufactured in annual volumes of 20,000 units or less.
# The vehicle is, and was manufactured as, a two-door coupe or a convertible.
# The vehicle is, and was manufactured as, a high-performance vehicle.
The only issue of getting a car under a SIV permit is "A special interest vehicle cannot be sold or leased within four years of its registration in New Zealand."
