Hi Casso.
Best bet is to goggle for the tourist spots, you can also get the weather on NZ met office site.
Seems that you intend to do a lot of driving. Remember we drive on the left here and there are not many motorways. Most of the roads are 2 lanes , one each way and everybody has to use these roads so its slow going sometimes. especially when truck n trailer units are governed to 90kph. Just allow that extra bit of time .
Enjoy your stay.
PS Dont worry about our sheep, the ones John in a daze went out with have long gone to the paddock in the sky, still laughting.
