I’m considering hiking the Te Araroa Trail next season. It would be a January 2017 start, the reason for starting later is so I can work full time at my retail job over the holiday season and save up as much as possible. I’m an experienced backpacker and I don’t have a problem with the route finding, rough terrain, or bad weather but I don’t have any long distance through hiking experience.
I realize that makes it a race against winter, but I’m thinking about a Northbound trip so I end later in the season in at the more temperate North Island, but I really know very little about new zealand. When I’m thinking about the time of year, in my mind I’m adding +6 months. So January similar to a North American July, May similar to a North American November. Is that a good way to look at it? Will it get sketchy ending in Novemeber/December on the North Island? Are there alpine areas on the North Island where I could get snowed out? How much rain does the North Island get in fall/early winter?
I’m also thinking Northbound would be best so if I decide I’m done with hiking by the time I get to the North Island, at least I got to experience the more wildernessy South Island during prime season.
I also had a few other questions.
What’s the longest stretch without a resupply? Are there sections where I need to carry a lot of water? Trying to figure out how much pack volume I need.
Do I need a shelter with bug protection?
Are there long stretches above the treeline? Normally I use my tarp and pitch it off trees but if I’m going to get stormed out a lot above the treeline I should probably have a mid.
Are there sections where you can’t camp out wherever and have to stay in a hut/hostel/developed campground?
What kind of weather should I be prepared for? I’ve heard that you can get days of rain, but is it generally warm rain or cold rain? Does it get cold enough when it storms to consider carrying rain pants? Should my western mountaineering 32 degree summerlite get me through the entire thing or should I have a slightly warmer bag?
How much cash $$$$ should I have to spend? I would buy all my food along the trail.
Also curious about the general experiences, good and bad, that other hikers have had doing the trail. Thanks!
