members. Mayoral and ministerial vehicles used the prefix "CR" (Crown). The Prime Minister receives plate CR1 while the plate DC1 is reserved for the British High Commissioner to New Zealand. As the official representative of the monarch in New Zealand, the Governor General's primary vehicle carries no number plate but instead displays the royal crown. It is the only standard car permitted to operate on New Zealand roads without a number plate. However, in the NZTA System, the combination "CROWN" is used, and was issued in 1986, predating all other personalised plates by two years. Since the change to the LLLnnn format, the letters I, O and X have appeared only on plates starting with "AAI", "AAO", and "AAX" respectively; presumably the potential for confusing these letters with numbers and other similar looking letters was only realised after those initial series. plates eschew the letters I, O, V, and X, meaning that letter sequences skip straight from HZZ to JAA and NZZ to PAA. A number of three-letter combinations have been skipped, mainly to avoid offence. These include: ARS, ASS, BAD, BAG, BAT, BRA, BUM, BUT, CNT, CUM, CUN, DUM, FAG, FAK, FAT, FCK, FKN, FKQ, FKU, FQM, FQN, FUC, FUK, FUQ, FUZ, HAG, JAP, JEW, KFC, KGB, KKK, KLL, KNT, KUM, LSD, NAZ, NGA and PEE. Despite possible negative connotations, the FTP and GAY combinations were issued during 2011 and NGR in 2021. Some MG models featured plates with serials in the MG series, used as semi-personalised plates, in advance of the official MG release. The full BMW series has been bought up by BMW dealers for similar use, while some Hyundai and Kia cars feature plates with serials in the HYU and KIA series respectively. Serials in the CCC and DCC series have been reserved, presumably for diplomatic vehicles. The combinations EBA, FCC, FNA–FNZ, G(A–H)A, MMM, NWA, PCP, PDW, and PFZ were also excluded.

Originally black, these plates later became yellow in colour. In May 2019, after the Christchurch mosque shootings, the NZTA offered to replace any plates with the prefix "GUN" (issued in 2013) on request, although the series was not withdrawn.
