New Zealand television channel

TVNZ 1 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.

At 7:30pm on 1 June 1960, New Zealand's first television channel, AKTV2, started broadcasting in Auckland from the NZBC building at 74 Shortland Street, previously used to broadcast public radio station 1YA and now home to The University of Auckland's Gus Fisher Gallery. Owned and operated by the New Zealand Broadcasting Service (NZBS, which became the New Zealand Broadcasting Corporation in 1962), it initially broadcast for two hours a day, two days a week. Christchurch's CHTV3 followed in June 1961, Wellington's WNTV1 a month later, and Dunedin's DNTV2 on 31 July 1962. Television licences were introduced in August 1960, initially costing NZ£4 (equal to NZ$171 in December 2013). Television advertisements began in April 1961 and were initially allowed only on Tuesdays, Thursdays and Saturdays. By 1965, 300,000 television licences had been issued, and television was broadcasting seven nights a week. To forward this to the South Island, the NZBC positioned one of its first outside broadcasting vans to beam the footage to a receiving dish across Cook Strait, from which it was forwarded through the recently commissioned South Island network. The link was completed later that year, the first NZBC Network News transmitted on 3 November, read by newsreader Dougal Stevenson. For the first 13 years, NZBC TV broadcast solely in black and white. Colour television, using the Phase alternating line (PAL) system, was introduced at 7:45pm on 31 October 1973. The first programme broadcast in colour was American reality show Thrill Seekers. A major impetus for the move to colour was Christchurch hosting the 1974 British Commonwealth Games; however, due to limited colour facilities, only four of the ten sports (swimming, diving, athletics and boxing) could be broadcast in colour. Most programming transitioned to colour over the following 18 months. The Network News continued to broadcast in black and white until 31 March 1975; this was to avoid refitting the existing Wellington studio with colour equipment ahead of the imminent move to the new Avalon Television Centre in Lower Hutt.

On 1 April 1975, the NZBC was split into 3 separate state owned corporations: Television One, TV2 and Radio New Zealand. The existing NZBC television service became Television One, and was based in Avalon Television Centre which opened that day. Television One used the WNTV1 and DNTV2 studios and the existing channel frequencies, while AKTV2's Shortland Street studios and CHTV3 studios and new channel frequencies were used for the new TV2, which commenced later that year. Television One commenced transmission on Tuesday 1 April 1975 at 2pm with a five minute news bulletin read by Bill McCarthy, followed by the British drama series Harriet's Back in Town. Its two hour opening special was broadcast live to air at 7pm that night and featured a preview of the programmes, plans and personalities for the new service. On Saturday 17 July 1976, after snow and gale force winds cut mains power to the Blue Duck microwave station near Kaikoura, the station's diesel generator failed and left it running on batteries. The batteries eventually discharged by 7pm that night, severing the Television One network feed south into Canterbury, Otago and Southland. Technicians couldn't reach the station to repair the diesel generator and restore the network until late on Sunday morning, meaning most of the South Island missed the live opening ceremony of the 1976 Summer Olympics.

In 1980 the two television channels merged to form Television New Zealand, with the purpose of finally providing a dividend to the Government. The merger was promised to provide 'complementary programming' for both channels. The channel was renamed as "Television One" until early 1995, when it was announced on air as just "TV One". Regional news programming was reintroduced from 31 March 1980 screening at 7.30pm for half an hour. It aired twice a week in the afternoon. The initial editor was Chris Mitson, later replaced in 1982 by Chris Shellock and David Shellock. Mitson came up with the programme's name while he was at a pub. In 1982, the regional programmes were incorporated into the network news bulletin with 7.30 South rebranded as The South Tonight. Each region would break out from the network news for a 20 minute regional programme before returning to the network news for the weather. In 1989 the regional programmes were transferred to Network Two in the new timeslot of 5.45pm, and Top Half and Today Tonight were axed later that year. In 1990 The Mainland Touch and The South Tonight were transferred back to Television One and screened immediately after the Māori news programme Te Karere (live at 5.20pm in the North Island, delayed at 5.35pm in the South Island) and before the network news. Both programmes were axed altogether at the end of 1990. In August 2008, TV One, along with TV2, moved to 720p high definition for the start of the 2008 Summer Olympics in Beijing. Both channels were originally only available in high definition on the Freeview HD platform, before commencing high definition broadcasts on the Sky platform on 1 June 2009 now moved to 1080i in August 2010. In October 2016, the channel was renamed TVNZ 1.
