My backpack is mostly packed with t-shirts and shorts for Thailand and Aus. I do have a couple a pair of Jeans and a couple of jumpers too.
What is the weather going to be like? Do I need to pack my winter gear? I'm there for the whole month of july and I will be travelling from North to South.
If I can afford to do a bit of snowboarding will all the gear be available for hire? How much would it be do for 3-4 days snowboarding including hiring gear?
I would say definately winter gear. I was in South Island last March and it was soooo cold and only autumn. Amazing country you will love it!!!
Well I would clear out some room from your pack. Your going to Thailand, I would take 3 t-shirts 1 pair of jeans, 1 pair of shorts, and 1 Jumper.. You will not need all of that and if you need to you can shop in Thailand and buy a bunch of cheap stuff. No point loading down your pack. Then you will have room for the winter stuff you will need in NZ.
The South Island will be cold, but not quite as cold as a British winter unless you are right near the bottom of the island. The top of the north island will be mild - Auckland averages 13-15 degrees on winter days but is cold at nights. Everywhere can be very wet in NZ so make sure you have waterproofs and plenty of warm clothes. It's a nice time to travel around though - less tourists and beautiful snow-capped mountains.
haha leave it to the australian to say you definitely need winter gear.
it will get cold in the south but nothing too bad. You're from england, I'm sure you are used to some cold winters. just wear a few shirts and a thick jumper. it's all about layers. bring a rain jacket for the north island though.
