TVNZ 1 (Māori: Te Reo Tātaki Tahi) is the first national television channel owned and operated by the state-owned broadcaster Television New Zealand (TVNZ). It is the oldest television broadcaster in New Zealand, starting out from 1960 as independent channels in the four main centres of Auckland, Wellington, Christchurch and Dunedin, networking in 1969 to become NZBC TV (although the individual facilities retained their call signs into the 1970s). The network was renamed Television One (TV ONE, stylized as oɴe) in 1975 upon the break-up of the New Zealand Broadcasting Corporation, and became a part of TVNZ in 1980 when Television One and South Pacific Television (now sister channel TVNZ 2) merged. The channel assumed its current name in October 2016. TVNZ 1 is both a public broadcaster and a commercial broadcaster. Central to TVNZ 1 is news and current affairs, which is produced under the banner 1 News. Also, it broadcasts sports programming under the banner 1 Sport. Other programming targets the 25 to 54 demographic, and consists of mainly drama, general entertainment and documentaries, both locally and internationally (especially British) produced.
