preparations and vacation in NZ

to return to the north island (I will return the camper in Christchurch CHC) from the south one, I just booked a flight on the 16th March, 120NZ$, so round 'bout 60eu...much less than the 200 for the ferry ;-) I bet that this low price would be higher if booked not that early. Flight time is 1:20h. Then I will stay the last night in AKL and then the long flights back to Germany on Saturday 17th. Confirmation came by email, booking via creditCard was pretty easy and straight forward on the web
