The ratings head-to-head between Seven Sharp and Campbell Live reveals TVNZ's new offering outperforming TV3 in total audience terms all but twice in its first two weeks.
But over the same period, the TVNZ show lost the key demographic both channels are chasing, those aged between 25 to 54, eight times.
Figures supplied by Nielsen TAM show that apart from the first big bang on February 4 where 508,500 tuned into Seven Sharp compared to 246,300 on TV3, there have been plenty of nights where the two have been separated by barely a percentage point or two of the total television audience.
For Campbell Live, February 12 was historic. It was the first time the channel won the slot since TV3 began in November 1989, a win it repeated three days later by taking 7.2 per cent of the total audience aged five and over with 298,800 viewers to 242,300.
Media commentator Dr Brian Edwards said the results were instructive as they showed an "evening out" of ratings between the competitors.
