The authority found that the complainant was identifiable, despite the blurring, by her clothing, body type and voice, and possibly other details.
It found that the broadcast revealed private facts about her, including that she was taking prescription drugs and that her partner was in prison, and that the disclosure of these facts would be "considered highly offensive to an objective reasonable person".
In response to TVNZ's submission that the footage carried 'direct public interest' because it showed the consequences of smuggling contraband into prisons, the authority said, "TVNZ could have communicated these public interest messages without disclosing [the complainant's] identity."
"This could have been achieved, for example, by using pixellation that properly concealed the features of the complainant, avoiding full-body shots and masking her voice."
The authority awarded $1,000 privacy compensation to the complainant for the breach of her privacy.
