Paul,
you're in nz so any care you require for this injury will be covered by acc. You should go to a dentist or doctor asap. The cost of the consultation will be covered by acc - you shouldn't have to pay for anything. The most important thing is to get a claim put in, so any other issues caused by this accident in future will also be covered. This is really important for for a dental injury, because there's a high likelyhood of problems in the future, even if you think that you're teeth aren't damaged now. Sometimes when you get a knock in the teeth, the nerves die, but you don't have any symptoms until later, even years later. Go and get a claim put in and xrays done. Go! Now!
I don't know about your lip, tho, sorry. See a doctor or a dentist.
