New Zealand Number Plate Recognition API

New Zealand runs a single national plate scheme — black characters on white, issued in sequence to every vehicle in the country — which makes it one of the cleaner ANPR markets anywhere. The catch is everything around the standard plate: personalised plates of up to six characters in almost any combination, distinct trailer and motorcycle formats, and older black plates still carried by classic cars.

A parking building in Auckland will mostly see standard plates, but the misreads that break automation come from the exceptions — a personalised plate that spells a word, a trailer plate on a boat trailer, a grimy plate in winter light. Our models handle the standard sequence and the exceptions alike, with an honest confidence score on every read — 97%+ accuracy at under 200ms.

Coverage

The national scheme and its exceptions

Standard NZ plates are issued nationally in sequential series of letters and digits, currently six characters long. Personalised plates can be nearly any combination up to six characters, while trailers and motorcycles carry their own shorter formats.

Because there is no regional coding to extract, the value is in clean, reliable reads: the API returns the characters exactly as printed, distinguishes plate formats where they can be inferred, and reports confidence per read so your gate logic knows when to ask a human.
