TVNZ7 will switch off for good at midnight on June 30, despite supporters of the television channel seeking legal advice over the government's decision to axe it.
TVNZ7 - the country's only commercial-free public service TV station, which airs news, current affairs and panel discussion shows - will close after the government last year decided not to extend its funding.
The channel will become a TV One Plus One channel from 7am on July 1 and will be a repeat of TV One with a one hour delay.
The TVNZ7 website will also close down, although the TVNZ7 Learning Hub website will be available until next year.
A group battling to save the channel has hired top public lawyer Mai Chen to evaluate its legal case against the government.
Save TVNZ7 spokesman Myles Thomas told the Dominion Post Ms Chen will examine whether the government's decision to stop funding the channel was lawful, and whether the group could seek a judicial review.
Ms Chen was expected to decide before the end of the month whether she will take legal action on behalf of the group.
