Travel Packing Checklist for Kiwis Heading Overseas

What documents do you need to pack for an overseas trip?

Start with the paperwork, because it's the one category you can't fix at the destination. SafeTravel, the New Zealand Government's travel advice service, says your passport should be valid for at least six months after your planned return date, and that you should carry copies of your passport, visas, prescriptions and insurance policy, kept separate from the originals.

Entry rules differ from country to country and change often, so check each destination's official requirements before you book rather than relying on an old trip. Our guides don't state visa fees or durations for that reason - SafeTravel and the destination's own government site are the places to look.

• Passport and visas - Check the expiry date now, not at the airport. Photograph every page and email the images to yourself.
• Travel insurance - SafeTravel notes that even minor medical treatment overseas can be costly, and that policies need to cover what you actually plan to do, such as scooter riding or scuba diving. Save the policy number and the emergency phone line offline.
• Cards and a little cash - Take two different payment cards and keep them in separate places. A small amount of local cash for arrival is handy, but you rarely need much.
• Bookings and addresses - Screenshot flights, accommodation addresses and any onward tickets so they open without a connection.
• Register your trip - It takes a few minutes on SafeTravel and is how the government contacts New Zealanders in an overseas emergency.

What can you put in your carry-on from New Zealand?

On international flights, the Civil Aviation Authority's passenger information says liquids, gels and aerosols in your carry-on must be in containers of 100ml or smaller, and some powders are capped at a combined 350ml. Anything bigger goes in checked luggage. There are exemptions for medical needs and for a baby travelling with you. The rules have been loosened a little in recent years, for example around taking liquids out of your bag at screening, so check the current wording on the Civil Aviation Authority's passenger pages or your airport's site before you fly, as it can change.

The same flyer says loose batteries, power banks and earbuds belong in your carry-on, not your checked bag. Individual airlines add their own limits on where you can charge or stow power banks, so check yours. It also lists carry-on limits on hand tools and knife or scissor blades, so leave multi-tools in the checked bag.

• Toiletries - Decant into travel-size containers, or buy full-size at the other end. Put anything over 100ml in your checked bag.
• Power bank and cables - A power bank, a short charging cable and a wall charger with the right plug for your first country.
• A change of clothes - One top, underwear and socks in your carry-on cover you if your checked bag turns up late.
• Empty water bottle - Fill it after security so you aren't relying on cabin service for hours.

How do you travel with medicines from New Zealand?

Pack your regular medicines in your carry-on, in their original, labelled packaging, with a copy of the prescription or a letter from your doctor. New Zealand Customs sets out the same approach for medicines coming into the country: original containers, plus a prescription copy or doctor's letter, and no more than about three months' supply of non-controlled prescription medicine. Controlled drugs have stricter rules and must be declared, and medicines containing pseudoephedrine count as controlled.

Other countries have their own rules, and some restrict medicines that are common here, so check the destination government's guidance well before you leave. If you rely on a prescription medicine, ask your doctor early about how much you can take and whether you need a letter. A small first-aid kit with pain relief, plasters, antiseptic and rehydration salts covers most minor problems.

What tech should you pack, and what can you leave behind?

Keep it light: your phone, charger, a power bank, headphones and a universal adapter cover most trips. A laptop or tablet is worth the weight only if you'll use it. Download maps, tickets and entertainment on Wi-Fi at home so you aren't burning mobile data on them overseas - our guide to how much data you need overseas shows what common apps actually use.

Before you fly, back up your photos and make sure your phone is unlocked and updated. A phone that is locked to a New Zealand provider may not accept another eSIM, which is worth finding out at home rather than in an arrivals hall.

How do you sort your phone before you fly?

Roaming on a home plan can get expensive fast, and a local SIM means finding a shop after a long flight. The easier option is to install an eSIM at home. Apple's support page explains the process on iPhone: connect to Wi-Fi, scan the QR code or follow the install link, and the plan appears alongside your usual line. Android phone makers publish similar steps for their own devices.

Pick a plan for the country you land in first. A Japan eSIM works for a Tokyo-to-Kyoto trip, a Thailand eSIM suits a beach-and-city fortnight, and the USA eSIM plans cover a road trip or a week in New York. Popping across the Tasman? See our Australia eSIM plans. Prices change, so the destination pages show live pricing, with $4.99 the current starting point for Japan.

If you're weighing it up, our eSIM versus physical SIM guide lays out when each makes sense, and the setup guide takes you through installing before you leave home. Keep your home SIM in the phone as your second line for calls and bank texts, with data switched to the travel eSIM.

What clothes should you pack for an overseas trip?

Pack for the climate and the activities, not for every possible scenario. Choose a handful of tops and bottoms in colours that mix and match, one warm layer, a light waterproof, comfortable walking shoes and one slightly smarter outfit. Most places have laundry options, so a week's worth of clothes is enough for a month.

Check the season at your destination, which is flipped for many Northern Hemisphere trips. A long flight also means the cabin is cold and dry, so wear or carry a warm layer. For longer stays and working holidays, our OE planning guide covers the first weeks abroad, and our long haul flight tips cover what to do on the plane.

What do you need to declare when you fly back to New Zealand?

Pack with the return trip in mind. Everyone arriving in New Zealand, including returning Kiwis, must complete the New Zealand Traveller Declaration, either in the app or online. The Ministry for Primary Industries (MPI) says biosecurity risk items must be declared or put in a disposal bin on arrival. That includes food, plant and wood products, and used outdoor gear such as dirty boots and shoes.

Failing to declare risk goods can mean an instant fine, even if it was accidental. If you've been tramping or camping overseas, clean your boots, tent and poles before you pack. If you're not sure about something, declare it.
