Brasil are in for a very painful tournament - South Africa are the worst 3rd placed team for a pool, but they're as much better than Brasil are, than England were to USA; France as about as much better again. TBH, I'm a little concerned for safety with Brasil, and that's against France, Italy, RSA - not the big packs of Canada/England or the ruthlessness of NZ/Eng. Their place should probably have gone to someone like the Netherlands - who are both better, and have a longer history in the game (I believe they qualify simply by being the "best South American team" - in which case continental variety would suggest Kenya or Hong Kong would at least be safe).
NZ v Spain... how many points do NZ want? They're not renowned to being gentle with the minnows - will probably set themselves the target of beating Eng's score against USA.
ETA: Yeah, Brasil qualified by beating Columbia. They do also have a win against Netherlands - in the RWC warm-ups - of course, I've no idea how strong a team the Dutch would have sent out to S.America to help out another team, but still - good on Brasil (NB it was their 5th ever win, according to wiki).
