Hi John, thanks for your reply, its certainly comprehensive and very interesting. I spoke to my wifes sister in Wanganui at the weekend and read it to her over the phone. She lived in Nelson when she first went to New Zealand 30 years ago and knew many of the places you mention. She moved to Wanganui when she met, and married, a Maori and has lived in the North Island since then (my wife also has various cousins and aunts, who we dont plan to visit, in the south island in Christchurch, Ashburton and Greymouth). You say we will be visiting during the high season but after the school holidays (we plan to travel to the south island on 15th feb), does this mean we should book the campsites in advance or will it be ok to just turn up? Obviously one of the advantages of a camper is the freedom to stop when we feel like it so we would prefer not to be tied to an itinary if possible.
