But given it funds hundredsof hows, there's a lot of dross that never really sees public scrutiny.
The most famous of late is, of course, Spinoff TV.
The website, which for reasons no-one can really fathom, got $700,000 to indulge itself in a more visual version of what it does online.
Given it had never made TV before, it went pretty much the way you thought it would: straight to the dustbin of TV history. Virtually no one saw it after the handful who watched the first one ran for the hills, or in this case the remote.
And here is part of the problem is: the snobbishness that drives NZ On Air.
Regarding releasing figures about the success of their choices, an NZ On Air spokeswoman said: "I don't know there would be a great deal of appetite for it, because you are sort of inviting the court of public opinion to make decisions about things."
Oh my god. Public money for public consumption of product?! Heaven forbid those who pay and consume have a say! What on earth would we know about what we want to watch?
As a person who lives and dies in the court of public opinion every day, and has done for 36 years, can I offer this piece of experience?
Give it a go. It might sharpen your act, your outlook, and curtail some of your arrogance that is clearly present to make such an outlandish statement.
Now, ratings aren't everything, but they are without question a very concrete set of evidence that tells you whether you've hit the mark you were wanting to hit or not.
And yes, NZ On Air makes shows that may not be primetime or mainstream. But what it can't be allowed to be (and clearly increasingly is) is a workshop for the unemployed artist who has an issue to pursue, or an agenda to push, or a creative itch to scratch.
It's timely to do this because NZ On Air has already got a funding boost under this government, and is due for even more as the Minister pushes her agenda of more public TV, whatever that means.
Melissa Lee's bill potentially opens the door into a cloistered world of elitism, and very little accountability. If she can change that, all power to her.
