not have leading zeroes, starting with 1000 in the LLnnnn system and 100 and later 1 in the LLLnnn system. A commemorative series of plates celebrating New Zealand's national rugby union team, the All Blacks, follows the LLnnnn system but with a leading zero after the letters "AB" (for "All Blacks"), giving them the format AB0nnn. In 1990 a special series of commemorative plates marked the country's sesquicentenary. These had the format nnnnNZ, with the lettering in red on white. Personalised plates Rights to unique combinations of up to six characters can be purchased from a private company licensed by the NZ Transport Agency. The purchaser may acquire any unique combination that falls outside the standard numbering sequences (apart from derogatory, obscene, profane or intentionally confusing combinations, or if they promote violence, discrimination or bias) or standard numbers that have fallen into disuse. New Zealand does not require associating the plate with a vehicle, and allows outright sale rather than just a periodic lease. Although plate character/number combinations can contain "spaces", they do not form part of the unique identification and are typically not stored (for example, in Police computer-systems). Therefore, if a personalised plate such as "I A I" exists an owner cannot purchase a combination such as "IAI", and vice versa. The most sought-after combinations available as personalised plates (such as "A1" or "AAAAAA") became special "collector plates", with lettering in blue on white. These plates are often offered for sale at a significant premium to standard plates. In 2017 a number of proposed personalised plates (including OR6ASM, FK8R and 4UHOES) were rejected by the NZTA. Number-plate accessories A number of companies provide alternatives to the standard message plate. Number-plate frames attach to the plate and provide space for messages above and/or below the license number, thus potentially perpetrating advertising. Several Maori iwi promote identity and traditional graphic designs in frames. Number-plate lookup systems Section 236 and 237 of the Land Transport Act 1998 (LTA) allows public access to the Motor Vehicle Register maintained by the NZ Transport Agency. The Motor Vehicle Register records information about vehicles used on New Zealand roads and the persons responsible for their use. The information from the Register can be sourced directly from the NZTA as well as from third parties who include the information with their vehicle information reports.
