I will be in NZ in April and have googled what the weather will be like in NZ in both the North and South Islands. From what I can tell it will be autumn but I've also read you can get 4 seasons in one day. Just hoping to get an indication of what sort of clothing should I mainly pack for my 2 week trip. In addition to the normal everyday clothes I planned on bringing a pair of trainers, a good waterproof jacket. Will this be sufficient or will I need to pack more?
