The New Zealand Broadcasting Service began transmitting from AKTV2 Auckland at 7.30pm on Wednesday 1 June 1960, broadcasting for 2 hours per night, 2 nights a week.
A television licence fee was introduced in August, for the cost of £4.
In October transmission was extended to five nights per week.
On 1 April 1961, the first commertials were shown on New Zealand TV, but were limited to only 7 minutes per hour, on Tuesdays, half of Wednesdays, Thursdays and Saturdays. Transmission times were also increased to 28 hours per week.
CHTV3 Christchurch began on 1 June 1961, with WNTV1 Wellington beginning on 1 July.
In 1962 the New Zealand Broadcasting Service became the New Zealand Broadcasting Corporation (NZBC).
DNTV2 Dunedin began on 31 July 1962.
In 1964 transmission times were increased to 50 hours per week.
On Easter Monday 1968, the Inter Island Ferry 'Wahine' hit Barretts Reef at the entrance to Wellington Harbour, with 51 people losing their lives. As there was still no link between any of the four NZBC-TV Stations, CHTV3 sent a camera crew to Kaikoura on the north of the South Island to film an off-air receiver as the WNTV1 news bulletin was broadcast that evening. The crew then raced back to Christchurch, processed the film, and it was transmitted before closedown. Thus the terrible news broadcast was the first programme in New Zealand shown on two stations on the same day. This coverage won the WNTV1 newroom the World News Film Award that year.
A temporary national link was setup in time for the Moon Landing, being the first programme to be shown across New Zealand simultaneously. It was not live, however, as the footage had to be flown from Sydney as there was still no satellite link from overseas.
NZBC-TV began to be networked in 1973, thanks to an improved national link. WNTV1 became the center of the network.
Colour television was formally introduced on October 31 1973.
On 1 April 1975, the NZBC was split into 3 seperate state owned corporations; Television One, Television Two and Radio New Zealand. The Avalon Television Centre in Wellington opened that day and became the headquarters of TV One. WNTV1 and DNTV2 studios were used for TV One, while AKTV2 and CHTV3 studios were used for TV Two, which commenced later that year.
In 1980 the 2 television channels merged to form Television New Zealand, with the purpose of finally providing a divident to the Government. The merger was promised to provide 'complementary programming' for both channels.
