Amateur radio call signs of New Zealand : ウィキペディア英語版 | Amateur radio call signs of New Zealand The amateur radio call signs of New Zealand are unique identifiers for the 6,000 licensed ham radio operators in New Zealand. Call signs are regulated internationally by the ITU and nationally by the Ministry of Business, Innovation and Employment (MBIE), formerly the Ministry of Economic Development. The ministry is also responsible for providing policy advice to Government on the allocation of New Zealand's radio spectrum to support, efficient, reliable and responsive wireless telecommunications and broadcasting infrastructure.〔(Radio Spectrum Management )〕 ==History==
In 1924, New Zealand was granted the prefix 'Z',〔(http://www.nzvrs.pl.net/ccc/Orbell/milestones%20etc.pdf )〕 and in 1925 the number of licensed amateur reached 100. In 1927 the International Telecommunication Union Conference in Washington (D.C., USA) established internally agreed upon call sign prefixes – New Zealand was assigned 'OZ'. In 1929 this was expanded to the ZK–ZM letter block, with New Zealand opting for the ZL prefix for land based stations. 'OZ' by 1927 was reassigned to Denmark.〔(International Prefixes Starting With Letters )〕 In 1969 the ZM prefix was allowed to celebrate the Captain James Cook bicentenary. In 1974 the prefix was allowed again to celebrate the Commonwealth Games, as well as in 1989 when the Games returned. In 1981 the ZLØ prefix was allowed for visitors to New Zealand.
