Hey guys Im going to be staying at Carrington next year doing HSFY quite excited and nervous seeing as I won't know a soul down at Otago but Im sure things will be fine

Just wondering what sort of things you do in labs I mean I assume in HUBS you do dissections and such but what about for the other papers?
Yay, Carrington represent! You'll have a great time there - awesome hall (though I am just a bit biased on the matter).
As to your question, the labs are variable. Mostly they just reinforce lecture material through various activities - only in BIOC (and, to a lesser extent, CHEM) are the labs actually treated as learning opportunities in themselves. A brief summary:
BIOC - the best labs in my opinion. Focussed around learning important biochemistry laboratory techniques (e.g. pipetting, spectrophotometry, gel electrophoresis, centrifuging) and applying them (e.g. by measuring your own plasma cholesterol concentration).
HUBS - reinforce lecture material in a variety of ways, but generally pretty cool. The anatomy component usually consists of the chance to look at some real human prosections and occasionally do an animal dissection (e.g. deer joint), and the physiology component involves experimenting on yourselves (e.g. giving yourself an electric shock to make your muscles involuntarily contract).
CELS - pretty bad. The teaching staff themselves say that they are to "provide further assistance to struggling students", so you hardly do anything practical for yourself.
PHSI - take a more tutorial-style format with some activities to reinforce what you're learning (but nothing that far removed from what you'd do in school anyway). You can get through them really fast if you're up with the course content (my record was getting out 30 minutes after the lab had started).
CHEM - pretty much what you'd expect: a chemistry-related activity each session (e.g. titration). Some cool parts though (in one of the labs you get to make paracetamol!). Each lab has a test conducted in the lab under exam conditions that many people find quite difficult though, which can put a dampener on the whole thing.
