We had about 16 in my group and 8 in the other! It just all depends on the project needs. The first two weeks we all lived together on a marae. We worked together to do all the chores and cooking. The second two weeks about half us continued on to the adventure tour- the other group was really nice but by then we have already bonded to each other so we stuck together in our own groups!
I think i ended up spending around 6500 USD. You can definitely cut down that price but i did almost all the excursions! Also I brought about $300 spending money and my credit card! Don't try to tell yourself you'll just skip doing things like bungee or skdiving because its incredible. best trip of my life! Also its cheaper to skydive here than in the US (only about $450 USD) .
