Firstly, you are very lucky and we are so jealous having just returned ourselves from our round the world trip. We know that both the Cook Islands and New Zealand are a way off but both places are incredible. In Raratonga we stayed at Tiare Village. A woman called Mary runs the place with a lovely Raratongan lady called Lilly. If you stay there you will be guaranteed a good time and they will tell you everything you need to know. Here you will find paradise! Would not know where to start with New Zealand except it is the most beautiful country. Do the North and South Islands taking in Paihia in the far north and Milford Sound in the south west. We travelled round on Magic Bus which is easy, did all the must do's, and met loads of people. Whatever you do in New Zealand it is very traveller-friendly. Do not miss out on a glacier hike on either Franz Josef or Fox glacier (a full day hike is a must!). The skydive over Taupo is also excellent and the cheapest in the world. Anyway, bye for now. Have a great time.
