The BSA viewed and listened to the scene "a number of times" and never managed to determine what they were hearing.
"In our view, the word used was not 'freaking'. However, we were not able to determine whether the word used was 'f***ing' or some less offensive but similar sounding word," they BSA said.
"Just as we found it difficult to determine what was being said, so we believe most listeners and viewers would have had the same difficulty. The diction of the speaker was poor and what was being said was said quickly."
That said, the BSA said that when there is uncertainty about what was said, they do not uphold the complaint. They did however warn TVNZ to be more careful and clear in future.
TVNZ maintains the actor said "freaking" - as "confirmed by the closed captions" - and "freaking" is not a swear word by the BSA's definitions.
The producer of Shortland Street advised TVNZ that the word in question has never been used in an episode, due to the show's timeslot.
