Yes Paul Henry was a dick for his comment about the Governor General.
However, doesn't it show once again why you shouldn't be forced to have an ownership interest in TVNZ?
TVNZ should be privatised. The last National government was confidentially investigating exactly that at the time, but time wasn't on its side before the rise of Helengrad.
The rise of digital TV (first by Sky via satellite and Telstra-Clear via cable, some time before terrestrial broadcasting) will mean much more radio spectrum will be available for TV channels. There is no need for the state to own four of them.
TVNZ has long been a laughable excuse for a public broadcaster, caught between trying to be the lowest common denominator folksy, once over lightly, reduce everything to parochial or sporting analogies, asinine banality, with the ernest attempt to try to be the repositary of kiwi kulcha and the need to produce news and documentaries for adolescents.
Selling it would mean Paul Henry would be with an employer who would respond completely to what its customers (advertisers or subscribers) wanted.
At that point (and right now) you can simply abstain. Don't watch. If enough of you do that then the democracy of the market will remove him from the airwaves, but you can remove him from your screens now - just don't put that channel on when he is on.
