Transit visa in Chinese airports?

Question

I'm hoping to get a flight which requires me to be in China for 28 hours before the connecting flight out. I'm happy to sit in transit if I have to. However, I've read one site that said 12 hours is the max transit permitted.

Can anyone find either:

1) Definitive information saying how long transit in Beijing/Shanghai airports are for 2) Or can I get a transit visa on arrival, in which case I'll go check out the city for a day ;)

I'm on a New Zealand passport.

Failing all that I'll pick up a visa in Mongolia en-route, I'd just rather not have to waste a few days doing so if I don't have to!
