The authority found the broadcast did not contain sufficient balancing comment to enable listeners to arrive at an informed and reasoned opinion about the 'three strikes' law and whether it was operating as intended.
"The programme omitted any alternative voice to counteract the one-sided statements made by the panellists, and the presenter failed to adequately challenge those statements," the authority stated.
"Compounding this, the panellists also made statements which created a misleading impression in the absence of any balancing comment."
The BSA declined to uphold the complaints relating to fairness and responsible programming, finding the complainant's concerns were better addressed as matters of balance and accuracy.
The authority agreed with Mr Garrett that RNZ's website should contain either a statement or a link to its decision, alongside the audio for as long as it is online.
In another recently released decision, the BSA found an episode of the animated cartoon series Futurama, aired on channel FOUR, should have been classified PGR because it contained sexual content not suitable for unsupervised children.
The episode, which was classified G and broadcast at 6.30pm, contained sexual references and innuendo which the BSA said was targeted at a more mature audience.
The complainant wanted TVWorks to pay a donation to an organisation assisting child victims of sexual abuse, however the BSA does not have the power under the Act to order a broadcaster to do so.
The BSA was satisfied that publication of its decision was sufficient to address the breach, and acknowledged that the episode has since been reclassified.
