In its first week, the network held New Zealand's first Telethon in aid of the St John Ambulance.

It was another three months before the Waikato and Bay of Plenty got coverage and by late November, the channel was available in Wellington before spreading throughout the rest of the country.

In December 1976, TV2 was rebranded as South Pacific Television (SPTV) to distinguish itself from the former NZBC channel.

It was decided in 1979 by the National Government that the channels would be amalgamated under an administration which would end the competition that reared its head in 1975.

The final programme was a two-hour farewell special, and the channel closed down at 12:15am on the morning of 16 February.
