Tahiti isn’t much seen outside the islands. In 53 years, I have seen it twice in France and once in New Zealand, PLUS this very unusual Consular Corps version, un-noted in any official references to the islands’ plate systems. This Volvo Amazon was captured by VB in London around 1962
and the cheerful owner advised that he was the Danish consul in Papeete.
I went over there in 2000 and square-searched Papeete for any remaining evidence of consular plates, but there were none – just regular registrations with separate black on green ‘CC’ ovals. And Air New Zealand wouldn’t give me my money back!
The typical ‘TAHITI’ silver on red plate was carried at rear, used in the absence of a dedicated international oval, though officially, I suppose it should carry an ‘F’ oval.
(As should St. Pierre et Miquelon and Guiane etc. etc. etc. but how dull that would be!)
Anyone else seen a Tahiti vehicle outside the islands?
Addendum Nov 2011: Recent contact with the island motor bureau reveals that they are sure no such series has existed! They are sure CC IT 4 is not from Tahiti! (I wonder where that Dane is today? He could fill us in….)

The 1994 RPOW mentions IT as being the code for foreign residents, with the plates being black on green.
Maybe however made this plates added CC to them to fill up space knowing the owner was the Danish counsel? In some other countries without a diplomatic series it seems to be common to add CD or CC to regular plates.
The E-Type appears on the cover of a CD of Tahitian music, the discogs page for the disc can be found here;
