A recent survey of 600 young New Zealanders aged 15 to 21 commissioned by Family First showed 57 per cent of females and 45 per cent of males agreed there was "too much sex, violence, bad language on TV".
Thirty-eight per cent of females and 58 per cent of males disagreed.
Mr McCoskrie said the survey showed greater concern about sex, profanity and violence on television among older survey respondents.
"Our concern is that for the younger ones, 15 to 17, it becomes normalised which is our concern with broadcasting standards full stop in what you allow. The BSA tries to argue that they're representing community standards. We argue that they're creating community standards by normalising it."
But BSA chairman Peter Radich said standards of good taste and decency were changing as they always had.
"The pace of change is quickening and this is partly through the influence that the unregulated internet has, more especially on younger people.
"Some people find the pace of change unsettling and, as they are entitled to do, they complain. Complaints allow broadcasts to be measured against standards, they allow temperatures to be taken, and for our part, they are welcomed."
Deputy Chief Censor Nic McCully said unlike the Office of Film and Literature Classification, which had prescriptive legislation to direct its work, the BSA had less definite framework to operate within.
"They're looking at standards and probably offensiveness, where we're looking at injury to the public good."
Ms McCully said her office and the BSA had to try to balance a lot of competing interests.
However, Ms McCully offered practical advice on dealing with offensive television content. "If people don't like it they can turn it off or change the channel."
