TV3 has apologised on air for a story on the now-cancelled Campbell Live show, which showed footage of a woman they secretly filmed.
Margaret Harkema, a former director of the Valley Animal Research Centre, which carried out experiments on beagles, featured in five episodes of the TV3 current affairs programme in late 2011.
Before last night's Story - the current affairs show that replaced Campbell Live - aired, a message was displayed onscreen with a voiceover.
The message said that the Broadcasting Standards Authority found the programmes were inaccurate, unfair, based on "a pre-determined, narrow view of Ms Harkema and her practices", were wrongfully edited to portray Harkema as dishonest and left out important information that was inconsistent with Campbell Live's allegations.
It found Campbell Live didn't give Harkema a fair chance to respond, and "sensationalised or overstated the situation by failing to distinguish guesswork from fact".
