For winter break me and some friends did the Abel Tasman track in the north of the south island. We spent three nights in huts. Overall it was a great trip, weather was good, and we even took a day off of hiking to just hang out on the beach. The tides were really crazy, the water moved over a hundred yards inland during high tide at certain places! We also saw some crazy glow in the dark bugs while hiking in the dark. I went swimming for a second but as it is still winter, it was pretty cold. Anyways, it was nice to get out in the wilderness for a couple days.
A cool wood tepee during the first couple minuets of our hike:

Just some cool stream:

My great hiking crew:

During high tide the water would probably cover all this beach:

Also during the break my roommate Greg and his parents had us in for a night at their house, they were very nice and hospitable... cooking us a great meal. We spent two nights in Kaikoura which is on the east cost. Overall it was a great trip.
