About 100 people attended a Save TVNZ 7 meeting in Masterton on Monday to oppose the shutdown of the public service channel.
The station will close at the end of this month after the Government decided to cut its funding on June 30. The channel will become TV One Plus One.
The Save TVNZ 7 group and opposition politicians have held meetings throughout the country to raise support for the channel, and have collected signatures for a petition.
The meeting at the Masterton Town Hall was moderated by media commentator Martyn "Bomber" Bradbury and featured speakers including media expert Dr Wayne Hope, Green Party broadcasting spokeswoman Julie Anne Genter, and Labour MP and former television journalist Kris Faafoi.
Dr Hope said ahead of the meeting that he was impressed by the turnout at meetings, particularly a Wellington gathering that attracted 1200 people.
