New Zealand is a driving country. Almost every itinerary is a road trip, the scenery people come for is in the places furthest from towns, and the coverage map reflects exactly that. It is well covered where people live and genuinely empty where they do not.
State highways good, the interesting bits variable
Auckland, Wellington, Christchurch, Queenstown and the main state highways are well covered. The populated east of the South Island and the North Island's main corridors are fine.
The gaps are not small. Fiordland has very little — the road to Milford Sound loses signal for long stretches and Milford itself is marginal. The West Coast between Westport and Haast is intermittent. The Southern Alps away from the resort towns, the Catlins, the East Cape and the central North Island volcanic plateau all have real dead zones.
The Great Walks and the Department of Conservation hut network should be assumed to be entirely without coverage. That is the design rather than a shortfall, and it is why the hut and track safety systems do not rely on phones.

Live prices in GBP, updated from our network partners. 6 plans currently available for New Zealand. Validity counts from the moment the eSIM first connects to a network in New Zealand, not from when you buy — so installing days before you fly costs you nothing.
£1.99 is the entry price rather than the best value. At £1.99 per gigabyte it is the most expensive data on the list; the 20 GB plan at £20.49 is £1.02 per gigabyte. If there is any realistic chance you will use more than 1 GB, the larger plan costs less than buying the small one twice.
Roaming, and whether you need this at all
New Zealand is a long way from any roaming agreement that would help a European or North American visitor, and standard roaming is expensive. One roaming partner network is available to us here, so the plan's coverage is that network's coverage — which on the main routes is good.
Plan the drive, not the day
The right habit in New Zealand is to download the offline map for the whole island rather than the day's route, because the point at which you want to change plans is rarely the point at which you have signal to do it. Fuel stops in particular are further apart than visitors expect on the West Coast and through the centre of the South Island.
Weather closes roads here, especially the alpine passes and the Milford road, and the official road information is online. Check it while you have signal in the last town rather than at the point where the sign says the road is shut.
And if the trip involves walking: tell someone your plan, because the phone is not a backup in the places you are going.
The networks you actually connect to
In New Zealand our plans roam onto One NZ (5G). That is worth stating plainly because it is the thing that determines your experience: a travel eSIM does not have its own masts, so your signal is whatever those operators have built, and 5G is available where they have deployed it and your handset supports it.
It also means no provider can sell you better coverage in New Zealand than the local networks have. Where there is a gap, it is a gap for everyone — local customers included.
Before you buy
Check the handset takes an eSIM and is not carrier-locked. Dial *#06# and look for an EID alongside the IMEI — no EID means no eSIM hardware whatever the model name suggests, and a locked phone will install the profile and then refuse to register. The device compatibility guide lists what works.
Then install before you fly, while you still have reliable Wi-Fi. Setup by brand: iPhone or Android. If it will not connect after you land, this works through the causes in order.
