TVNZ's Seven Sharp programme, which debuted last week, hit rock bottom on Tuesday night when ratings showed TV3 rival Campbell Live was on top.
It is the first time this has happened since John Campbell's show appeared on television screens in 2005. It is also the first time TV3 has beaten TV One in the 7pm weekday slot since TV3 began in November 1989.
Ratings for Tuesday's programme illustrate the danger that older Seven Sharp viewers - carried over from its predecessor, Close Up - are migrating to TV3.
The figures for Tuesday also back up indications it is not reaching the younger viewers it is targeting with its focus on social media.
Nielsen TAM figures show Campbell Live had 352,600 viewers compared with 296,700 for Seven Sharp. It is the smallest audience for the programme since it started last Monday.
