Hey Stef - I can help if you are headed to Wellington in terms of meeting people and knowing what to do. Are you tiki touring around or just staying with your sister? The old staying in backpackers is the best way to meet people or taking the contiki tours around the country. Other than that, from your activity posts, it seems you are on the right track. Another site to put a post is TradeMe (the kiwi equivalent of Ebay). Hope this helps.
