We cycled around New Zealand, mostly the south island. We covered about 3200 km from January to March 2003. It was Summer during that time and the weather was mostly good, apart from when we went south of the south island and we were stuck in our tent for 2 days. Incidently, I nearly burnt down the tent trying to prepare so tea with our travel stove.
So what is there to say about New Zealand? There are two major islands, the south and north island. The capital is Wellington, which is south of the north island, with about 200.000 inhabitants. Five times less than Auckland, which is north of the north island. NZ rather small and is very varied in landscape. Which makes it a perfect destination for cycling. It is similar to Norway and Scotland.
