Staying connected in New Zealand
Roaming, local SIMs and eSIMs, and where the signal runs out
Your phone will do a great deal of work in New Zealand: maps on long drives, booking the next night, checking the weather before a pass or a walk. The first question is whether your own UK plan already covers New Zealand. For some it does, at no extra cost. For others, roaming costs a daily charge, and a local SIM or eSIM will be cheaper on a long trip. The second thing to know is that coverage reaches most people, not most of the land. The towns and main highways are well served, but mountain roads, national parks and the backcountry often are not, and that matters for safety as much as for convenience.
- Check your own plan first. Some UK plans include New Zealand; many charge by the day.
- On a long trip, price a New Zealand SIM or eSIM against that daily charge.
- Make sure your phone supports 4G calling (VoLTE). New Zealand’s networks have switched off 3G.
- Download offline maps for the regions you will drive through.
- Walking beyond coverage? Carry a personal locator beacon, and tell someone your plans.
Our own experience was simple. We were on an O2 Volt plan in March 2026, and New Zealand was included: we used our phones exactly as we do at home, for maps, calls and messages, with nothing to buy and nothing to set up. It was very helpful. Whether you will be so lucky depends entirely on your plan, which is why we check it first.

Roam, or buy local?
There are three ways to stay online, and the right one depends on how long you stay and what your own plan includes.
| Option | What it costs | Setting it up | Best for | The catch |
|---|---|---|---|---|
| Roam on your own network | Nothing extra on some plans; on others a daily charge, usually around £7 to £8 from UK networks | Nothing: switch on data roaming | Short trips, and anyone whose plan already includes New Zealand | A daily charge mounts up over a three-week trip; some passes slow your data |
| A New Zealand SIM | Visitor packs from NZ$29 (One NZ); Tourism New Zealand puts ordinary prepay packs from about NZ$15 a month | Buy at an airport store or in town; swap the SIM | Long stays, heavy data use, calling New Zealand numbers | Your UK number is out of the phone while the SIM is in, unless the phone takes two |
| An eSIM | Visitor eSIMs from New Zealand networks, or data-only eSIMs sold online | Download before you fly; some activate only on arrival | Phones that support eSIM; keeping your UK number live alongside | Check whether it includes a New Zealand number, and that your phone supports eSIM, before you buy |
The sum is a simple one. Multiply your network’s daily charge by the days you will use your phone, and compare it with a visitor SIM for the same period. On a long trip, a daily charge soon passes the cost of a local SIM; for a few days it may not. If your plan includes New Zealand, as ours did, there is no sum to do.
If you are coming from the UK
New Zealand is outside the European roaming zone of every UK network. The allowance you use in Spain or France does not apply. What happens instead depends on the network and, often, on the plan and the date you joined it.
| Network | How New Zealand is treated | What to check |
|---|---|---|
| O2 | In O2’s Travel Inclusive Zone: roam at no extra cost on Pay Monthly Volt and Plus plans. Otherwise O2 Travel at £7 a day, with data limited to 2Mbps. Not available on Pay As You Go | O2 Travel and the Inclusive Zone |
| Three | Listed as a Go Roam Around the World destination. £7 a day, or £8 if you joined from 18 December 2025 (charged from 1 April 2026); £5 on some Lite plans; older plans differ. Up to 12GB a month. Value and Complete plans include roaming or Go Roam passes | Three Go Roam · destinations |
| Vodafone | Zone C, ‘Global Roam’. A daily charge of £7.39 was reported in March 2025; we could not read Vodafone’s own current terms | Vodafone roaming |
| EE | We could not read EE’s current terms for New Zealand. New Zealand is outside EE’s Europe zone, so the European allowance does not apply | EE roaming charges |
Daily charges are usually taken only on days you use your phone abroad, but read the terms for your own plan. Check through your network’s app or account before you fly; the plan you are on decides the answer, not the network’s advertising.
Buying a New Zealand SIM or eSIM
New Zealand has three mobile networks: One NZ (formerly Vodafone New Zealand), Spark, and 2degrees. Each sells a pack aimed at visitors.
One NZ’s Travel SIM costs NZ$29 for 30 days, rising to NZ$99 for 90 days, with calls and texts to New Zealand and Australia. The page we read gives the prices but not the data in each pack, so check before you buy. It is sold as an eSIM online, activated by calling 777 once you land, or as a physical SIM at One NZ stores, including at airports.
2degrees’ Unlimited Travel SIM gives unlimited New Zealand data, minutes and texts, under a fair use policy, for one price set by the length of your trip, with extra days from NZ$5. It is sold at selected airports and tourist destinations and in 2degrees stores, or ordered in advance.
Spark’s visitor page would not load for us, so we cannot report its packs. Spark says its 4G and 5G reach 99% of New Zealanders. None of the three pages we read said whether you need a passport to buy a SIM; take it with you in case.
New Zealand’s networks have been switching off 3G: One NZ’s switch-off notice said that by April 2026 it would no longer work in any form. Assume it has gone. A phone now needs 4G calling (VoLTE) to make calls. One NZ also warns that a phone bought outside New Zealand may not be able to call 111, the emergency number. If your phone is several years old, check its VoLTE support before you go, and do not rely on it as your only way of calling for help.
Where the signal runs out
Coverage figures count people, not land. Spark’s 99% is a share of New Zealanders, and most New Zealanders live in towns. Much of the country is mountain, forest and farmland, and there the signal thins or stops. The Rural Connectivity Group has built more than 570 rural sites since 2017 and covers more than 1,000 km of rural state highway, so the picture is improving. It is not complete.
We can name only the gaps an official source confirms. The Department of Conservation says there is limited mobile coverage on the Milford Road outside Te Anau, and lists card phones at Knobs Flat and Milford Sound and an emergency satellite phone at the Homer Tunnel; its page is several years old, so treat the details as a guide. On the Haast Pass road, the NZ Transport Agency has added what it calls a new ‘island’ of coverage at Pleasant Flat, between Haast and Makarora. Elsewhere, look at the networks’ own coverage maps, such as Spark’s, for the roads you plan to drive.
Our own memory is less precise. We think the signal dropped out at times on the Coromandel Peninsula, but we could not now say where. That is typical: on winding rural roads it comes and goes with the hills, and the useful habit is to plan as if it may not be there.
When there is no signal
Satellite texting is arriving. One NZ offers text and data by satellite on compatible phones anywhere with a clear view of the sky, free on its Pay Monthly plans and larger prepay plans and a small monthly add-on on others; its Travel SIM page lists a NZ$20-a-month satellite data add-on. One NZ warns that Android phones bought outside New Zealand may not be compatible. A 2026 industry report says Spark has a similar service; we could not confirm the details. None of the pages we read said whether visitors roaming from abroad can use these services, so assume you cannot unless you buy a New Zealand SIM.
For walks and remote travel, do not rely on a phone at all. NZ Police say a reliable signal in the backcountry or at sea is unlikely, and recommend a personal locator beacon.
A personal locator beacon sends a distress signal by satellite when a phone cannot. NZ Police recommend carrying one in the backcountry, learning how to use it, and registering it; beacons can be hired from many outdoor stores. Leave your plans with someone who will raise the alarm if you do not return, and see AdventureSmart for New Zealand’s outdoor safety advice.
2degrees says 111 can be called with no credit on its network. Download offline maps and keep a note of where you are going before you leave the last town.
Wifi
Do not plan on free wifi. Tourism New Zealand calls it limited: it exists in central Auckland, Rotorua, Wellington and Dunedin, at the main airports, in public libraries and many i-SITE visitor centres, and in some cafés if you buy something. Some places to stay offer it, so check when you book. If several of you share one data plan, a phone hotspot is the cheapest way to connect the others, Tourism New Zealand says.
Check your own plan before anything else: if it includes New Zealand, as ours did, you are done. If it charges by the day, a New Zealand visitor SIM or eSIM is likely to be cheaper on a long trip: price it against your network’s daily charge. Either way, assume no signal in the mountains, and carry a beacon where it matters.
— Andrew + MargaretA final word on staying connected
New Zealand makes it easy to stay online in the places most visitors spend their nights, and easy to lose the signal in the places they travel for. Sort the plan before you fly, download the maps, and treat the blank patches on the coverage map as part of the landscape.
