We are planning on spending 4 weeks in NZ end of January most of February 2019. We are 2 couples..us in our 60’s and daughter and husband in their 40’s. All of us pretty active. We want to do as much as we can of both North and South. First thoughts are to hire camper van but would we miss out on exploring the more ‘out of the way’ places? Would a 4WD and Airbnb/motels be cheaper? Is this a busy time of year for accommodation? All advice and itineraries welcome!
