What to Pack For 3 Weeks in New Zealand: Hiker’s Packing List

Figuring out what to pack for 3 weeks in New Zealand sounds like an ever-mounting task. If you’re planning on hiking and are unsure what to pack, this list provides everything you need to bring.

🇳🇿 This post is a part of my New Zealand Travel Guide.

Packing for a place you’ve never been to before is daunting. What is the weather like? Trail conditions? Where do I buy gear if I need something?

It’s all too easy to overpack and lug around heavy bags full of things you probably won’t use. I have been guilty of this. To combat the urge to overpack, I stick to a tried-and-true list that I know works.

Bring the essentials and leave everything else at home. I know that I have a better time when I’m not worrying about trying to wear all the outfits I brought and keeping track of a bunch of “stuff” when traveling.

The fewer things you have, the easier it is to relax and enjoy the beautiful places you’re visiting. After all, you’re coming to New Zealand to witness the incredible landscapes and explore the numerous trails — don’t panic about your packing list.

➡️ Looking for the perfect 21-day New Zealand South Island itinerary for hikers? I’ve curated the ideal list of things to do with a road trip map included.

Follow this guide for what to pack for 3 weeks in New Zealand to be prepared for your hiking adventures and casual exploration.

What to Pack For 3 Weeks in New Zealand

This list is geared toward hikers and summer weather, but it can also be modified for a more casual trip. You can skip to the end to find a bulleted list of items to pack for 3 weeks in New Zealand. But I recommend you read on to learn more about why I packed these specific items.

Test your gear before packing it for a trip like this! You don’t want to realize that your new hiking boots give you blisters or that your raincoat isn’t as waterproof as advertised. Try everything beforehand so you’re comfortable, and there aren’t any unexpected gear failures.

What to Wear Hiking in New Zealand

We were hiking in New Zealand in summer, between mid-February and mid-March. The temperatures on the South Island were lovely, not too hot, even on sunny days.

There was definitely some rain, and we came prepared to go out and enjoy the hiking tracks, no matter the weather. With the proper gear, we stayed warm and dry.

You’ll want to pack a mix of clothing. I actually leaned more on the warmer side because we hiked up hundreds of meters (thousands of feet) in elevation. Wind, rain, clouds, and early morning adventures also create a need for warmer attire.

Layers will simplify your wardrobe and keep you comfortable. When you’re planning what to pack for 3 weeks in New Zealand, layers are perfect.

Best Layers for Hiking in New Zealand

Aim to have a base-layer, a warm layer, and an outer layer that is both water- and windproof.

Sun Hoodies

Lightweight long-sleeve sun hoodies are going to be your best friend. Similar to Colorado, you can get sunburnt in minutes while you’re outside in New Zealand. UV levels are high due to less air pollution and the thinner ozone layer.

I’ve tried many sun shirts over the years, and my favorites are those made from merino wool (coincidentally, Smartwool and Melanzana both source their wool from New Zealand). Merino wool exhibits properties that synthetic fibers just can’t replicate.

Smartwool Ultralite Hoodie — My go-to lightweight merino hoodie. I’ve had this one for years, and it’s ideal for warmer weather.

Melanzana Merino Base Hoodie — Mid-weight merino that’s still comfortable for hiking in cooler temps. The Melanzana hoodie holds up better than the Smartwool, but it’s also thicker as a result. Buy online or book an appointment to shop in person at the Melanzana store in Leadville, Colorado.

Wool keeps you cool in warmer weather and warm in cooler climates. It’s all about the makeup of the fibers — they wick moisture away from your skin so sweat or water can evaporate.

➡️ I’ve got a whole post that explains the benefits of merino wool hiking clothes. Definitely check that out if you’re skeptical or want to learn more about this magnificent fiber.

If you’re looking for more budget-friendly options, you won’t find merino, but these hoodies are solid choices. I’ve had each for years, and they have stood the test of time.

REI Co-op Sahara Shade Hoodie — Not as breathable as merino, but a great mid-weight option. I do tend to get hot in this hoodie if I wear it on warm days.

Patagonia Tropic Comfort Natural Hoodie — Made from sustainable Beech tree pulp, this shirt is awesome for hot days. The material is thin and stretchy.

Hiking Pants and Shorts

Get yourself some quality hiking pants. I packed lightweight and mid-weight pants for 3 weeks in New Zealand.

My pants also acted as a water-resistant (not waterproof) layer in the case of a light sprinkle of rain. Pants protect your legs from rogue mud splatters as you walk — no need to wash off later.

Arc’teryx Gamma Pants — These mid-weight pants fit like a dream thanks to the adjustable belt. I am notorious for ripping pants, but these bad boys have held up over years of abuse.

Arc’teryx Gamma SL Pants — When something fits, I get two. The lightweight sister to the original Gamma Pants, these have the same adjustable belt.

I did pack two pairs of shorts and a skort, but I only wore them a couple of times for hiking. Pants are going to be the most protective. If you run warm, try a lightweight, loose pair of pants, and you might be surprised.

➡️ I struggled to find hiking pants that fit my curvier figure. If you still haven’t discovered a well-fitting pair of trousers, check out my post recommending hiking pants for curvy women.

Underwear For 3 Weeks in New Zealand

I think most women have a fear of running out of underwear. Weekend trip? Better pack six pairs of underwear, and then maybe a couple extra on top of that. I get it, I typically overpack in this department.

Invest in quality underwear and bras, and you won’t feel the need to change them after 10 minutes of sweating outside. Merino comes to the rescue yet again.

I can wear my Branwyn merino bra for many days in a row without washing it — no smells, no itchiness. Their wool underwear is also the most comfortable I’ve ever tried (although please don’t go multiple days without washing those…)

Because merino dries quickly, you can also wear your bra and underwear as a swimsuit in a pinch. Multi-use clothing is a traveler’s best friend.

Women’s Rain Gear for Hiking in New Zealand

Rain gear is essential for your list of what to pack for 3 weeks in New Zealand. If you’re exploring the West Coast of the South Island, it will rain.

➡️ While on the West Coast, our Franz Josef Glacier heli hike got canceled due to weather, and we ended up booking with Fox Glacier Guiding instead. Read my review of our Fox Glacier heli hike to find out if it’s worth it (spoiler: it’s worth every cent).

We hiked the Alex Knob track (on my list of things to do near Fox Glacier) and were grateful we packed raincoats and pants in our backpacks. When we turned around to trek back to the car park, the rain started coming down harder. Our hiking pants would have been soaked if not for our protective waterproof rain pants.

Patagonia Torrentshell 3L Pants — These have kept me dry on several occasions. The zipper on the side makes them easier to put on and take off while leaving your shoes on.

REI Co-op Rainier Rain Pants — My husband loves his REI rain pants. These pants are available up to 3X for more inclusive sizing.

Patagonia Granite Crest Jacket — Invest in a truly waterproof rain jacket. Your life might depend on it in the backcountry. I’ve worn this coat for backpacking, hiking, and casual rainy outings.

While walking around Hokitika Gorge in New Zealand, the rain was coming down so hard it felt like I was standing under a shower head on full blast. My Granite Crest Jacket kept all the water out somehow.

Warm Layers for 3 Weeks in New Zealand

I hardly travel anywhere without my Patagonia Nano Puff. It’s the perfect packable insulated jacket. You can layer it under a raincoat with room to spare, and the hood version comes in handy.

I’d also recommend bringing a lightweight (and an additional, optional heavier) fleece. These were excellent for layering and more breathable than the Nano Puff. I wore a fleece practically every day in New Zealand, as the mornings or rainy days could be chilly.

Patagonia Synchilla Pullover — A favorite of mine. It’s cozy and a bit oversized. The downside is that it doesn’t have pockets or a hood.

Melanzana makes my go-to lightweight hoodie, and I am also obsessed with their thick Wind Pro Hoodie. The hoods and kangaroo pockets on these are very useful.

A glacier guide in New Zealand actually asked me, “Is that one of those Mellys? Are they really as great as people say?” I was shocked that Melanzana, a little Colorado brand, was recognized halfway across the world.

I replied enthusiastically, “Yes! I love it, and I’m also wearing their merino hoodie.” Proudly showing off my layers to the glacier guide.

Make the trip out to Leadville and don’t forget to book your shopping appointment 9 months in advance. Yeah… they really do book that far out.

Shoes For Hiking in New Zealand

I only brought three pairs of shoes to New Zealand for 3 weeks — Chacos, trail runners, and waterproof hiking boots. These were a perfect combination, and I wouldn’t pack anything else.

New Zealand is a pretty casual place, and I saw quite a few people walking barefoot while out and about. Leave your heels and strappy sandals at home — pack for comfort and outdoor activities.

A note on NZ biosecurity hiking boots: Clean your shoes thoroughly before packing them. Declare your used outdoor gear (including tents, backpacks, boots, trekking poles, or anything that could harbor soil or seeds) on your New Zealand Traveller Declaration.

There cannot be any traces of soil on your gear, or you risk a fine. Check the New Zealand biosecurity requirements before packing your bags. If you’re unsure whether something needs to be inspected, declare it!

Chacos were ideal for walking on beaches, using public showers, and strolling around town. My Hoka Speedgoat trail runners were ideal for most hiking trails. I wore my waterproof boots on rainy days or when the terrain was gnarly.

Get yourself some shoe cover bags so you don’t get sand or dirt in your suitcase. I love the ones from Peak Design — they are just the right size.

Casual Clothes For 3 Weeks in New Zealand

Tank tops, t-shirts, and shorts were appropriate to pack for 3 weeks in New Zealand. I did bring a dress, but I only wore it once. If you are packing light, don’t worry about bringing nicer clothing, you won’t really need it!

Even in restaurants, the New Zealand dress code is casual. I never felt underdressed in athleisure. There were times I forgot we weren’t in Colorado, as the outdoor lifestyle is very similar.

Pro tip: Invest in expandable packing cubes if you haven’t already. I can fit all my clothes in a few of these bags. They zip down and compress the contents — packing more than non-expandable cubes.

Packing cubes are not only fantastic for your suitcase, but I also used them to keep my clothes organized in the campervan we rented. The overhead cupboards would have been a mess of outfits without these.

➡️ See my post for more tips on renting a campervan in New Zealand. It includes everything from selecting your van, what to pack vs. buy, and helpful tidbits.

What Gear to Pack for New Zealand Hiking Trip in Summer

My checked bag was full of hiking gear. I wanted to bring my entire closet of outdoor equipment, but let’s whittle down what gear to pack for 3 weeks in New Zealand.

Best Backpack for Hiking New Zealand

The backpack you pack for New Zealand very much depends on the type of hikes you plan on completing. We had a one-night backpacking trip on the itinerary, so I needed to bring a big day pack.

➡️ I compare backpacks and vests in my post about what to pack for a day hike. My 34L Osprey bag was terrific for a one-night backpacking trip (didn’t need a tent because we were staying in a backcountry hut). It features a built-in rain cover that I used a few times during our 3 weeks in New Zealand.

Hiking up Roy’s Peak for sunrise meant I wanted to bring warm layers in my bag that I could wear up at the top — and I certainly did.

For shorter, less intense treks, I opted to bring my Osprey hydration vest. The vest holds 1.5L of water and has room for snacks.

Gear For Backpacking in New Zealand

We saved space in our suitcases by not bringing a tent and choosing to stay in a hut. We did, however, pack our sleeping bags. I use a compression sack for packing my sleeping bag — it works like a charm.

Definitely bring a headlamp. We also used these for hiking before sunrise, and it’s always a good idea to have one on a hike.

You’ll need to have something to boil and/or filter water for drinking and cooking meals. We brought our Jetboil and purchased a fuel canister at Bivouac Outdoor. As a backup, we also carried a filtering bag system. It’s best practice to have multiple ways to disinfect water.

➡️ See my ultralight backpacking hygiene kit to help you pack backpacking toiletries.

Additional optional gear includes a backpacking pillow and a lightweight mug. You can bring a backpacking spork if you want to be extra, or just use a regular spoon.

➡️ Read my complete backpacking gear list to not forget anything important.

Don’t forget to carry containers with significant water capacity — whether that be a water bladder, bottle, or flexible water containers. I go over these options in my list of what to pack for a day hike (linked above).

Backpacking with trekking poles changed everything for me. Now, I don’t go backpacking without them. They take the strain off your knees and aid with balance for stream crossings.

Just like with shoes, make sure your trekking poles are clean of debris when you enter New Zealand. It was 100% worth bringing my poles, as many of the hikes we did in New Zealand were steep and long.

Travel Toiletries for 3 Weeks

➡️ My list of travel toiletries for 3 weeks morphed into an entire blog post that you can read. I delve into details, including the best toiletry bags, sustainable toiletry swaps, and discuss solid toiletry options (goodbye messy liquids).

The post is perfect for minimalist travelers, and even if you’re more of a maximalist, it’s a great place to start.

Electronics For 3 Weeks in New Zealand

Depending on where you’re traveling from, you might need an outlet converter. Get a universal worldwide converter rather than just an NZ/AUS converter. You’ll be able to use it wherever you go and won’t need to buy another one in the future.

I brought my camera and additional lenses. If you’re a photographer, a 24-70mm lens is a must. I don’t know how I ever got by without one. It’s become my favorite and, if I only bring one lens, that’s the one I pick every time.

Obviously, you need your various chargers. Phone, laptop, smart watch, headlamp charger, etc. Luckily, most things are USB-C these days, so that helps limit the number of cords you need to carry.

I packed my laptop for 3 weeks in New Zealand because I edited photos while we were there. Offloading images from SD cards and saving them to my laptop not only gave me peace of mind, but I was able to share photos with friends and family sooner than if I had waited until we got home to edit everything.

I do have a small battery pack, but I didn’t pack it because I felt like there were going to be sufficient outlets wherever we went. There were plenty of opportunities to charge on planes, in airports, in the car, at accommodations, etc. A battery pack would have been dead weight.

➡️ Headphones are on my carry on packing list for a long flight. I have pocket-sized wireless headphones and they are much easier to travel with vs. larger over-the-ear headphones.

The noise transparency mode is also useful for being aware of your surroundings while still listening to your music. You don’t want to be too zoned-out while walking in crowds, especially in places you’re not familiar with.

Packing List For 3 Weeks in New Zealand

Easily screenshot or copy this bulleted list. The number of clothing items stems from personal experience. You don’t need as much as you think you do. I overpacked, so you don’t have to.

We did go to a laundromat about once a week during our trip, and that was a perfect interval between washings.
