Is the hole in the ozone layer letting UVC rays in (just slightly)?

I have been doing a report on being sun-smart for school and one of the questions were "What are some reasons why it is important for New Zealanders to be Sun Smart?" I do NOT want you to answer that.
When researching about the hole in the ozone layer which is over New Zealand (where I live) I found about UVA, UVB and UVC rays.

UVA always go through the ozone layer. UVB is more dangerous (burns you, contributes to skin cancer, gives you cataracts, damages immune system etc) but most of it is absorbed by the ozone layer. UVC is extremely dangerous but is completely absorbed by the ozone layer. Then I thought "But what about the hole in the layer?" I can't find anything about it and I really want to know this (A) so I get a good grade on my report :D and (B) so I know for the future.

Does anyone know the answer? And also what the effects of UVC rays are because all the sites I have checked just say that it is dangerous and that it is completely absorbed by the ozone layer. Grrr. I want to put down what it does because I already have put down UVA and UVB rays. Please help. You won't be doing my entire project, only one or two sentences for one question.
